When fresh, stromata are typically 0.5–3 mm wide and 0.5–1.5 mm thick, pulvinate with varying outline and free, sometimes lobate margin; ostiolar dots lacking or inconspicuous, rarely appearing as dark dots or spots; ostioles only visible in longitudinal sections or from above at most as scarcely visible, minute, light dots; surface smooth, uneven or slightly tubercular, at first downy or velutinous, later often glabrous; in early stages in pale or light colours; yellow, pale orange to orange-brown or pale brown 5B5–6 to 6CD5–6, or reddish, later and at maturity typically dark reddish brown, 7–8EF5–8, 10CD7–8 to 9–10F7–8. Stromata when dry like the fresh ones, but distinctly flatter, mostly only up to 0.6 mm thick, discoid, flat pulvinate, placentiform or subeffuse; when young more distinctly downy than fresh, covered by brown hairs or finely velvety with short rust hairs, and surface more uneven, tubercular or rugose; colour medium to very dark reddish brown or nearly black, only rarely remaining orange-brown. Spore deposits white.</p><p>Stromal anatomy: Cortical tissue present around the entire stroma except for the point of attachment, comprising a <italic>textura angularis</italic> of rather indistinct and thin-walled cells with inhomogeneously deposited reddish brown to yellow- or orange-brown pigment. Hairs arising from surface cells usually abundant on young stromata, less common on mature stromata, 1- or several-celled, thin- or thick-walled, pale brownish, smooth to slightly verruculose. Subcortical tissue (below the cortex and between the perithecia) comprising mainly hyaline hyphae. Tissue below perithecia consisting of a more or less homogeneous, dense <italic>textura angularis</italic>–<italic>epidermoidea</italic> of hyaline to pale brownish, thin-walled cells, variably interspersed with hyphae; cells above the point of attachment sometimes arranged as a palisade.

Perithecia flask-shaped, ellipsoidal or globose, 150–350 × 70–300 μm; peridium hyaline, not changing in 3 % KOH. Asci cylindrical, containing 8 uniseriate ascospores. Ascospores hyaline, verruculose or spinulose, disarticulating into two cells in the ascus; cells dimorphic, distal cells (sub)globose, ellipsoidal or cuneate, (3.5−)4–6(−7.5) × (3−)4–5(−6.5) μm, proximal cells oblong, ellipsoidal, cuneate or subglobose, (3.8−)4.5–6.5(−8.5) × (2.7−)3–4.5(−5.8) μm.</p></sec><sec id="s3c"><title>Asexual morph (‘anamorph’) and culture morphology</title><p>All species included in the <italic>Trichoderma viridescens</italic> species complex have the following traits in common: green, verruculose conidia, submoniliform terminal conidiophore branches (= ‘eidamia’-morphology = repetitive phialides = percurrently proliferating phialides) on CMD (and PDA) with considerable variations including greatly swollen cells, and distinct coconut-like odour on CMD (and PDA). Conidiation on PDA is generally absent or poor and then effuse, on SNA and CMD in pustules, which are usually larger and more abundant on SNA. As repetitive phialides usually do not occur on SNA, conidiophores are here mainly described from CMD. The arrangement of conidiation structures on CMD varies from effuse over loose shrubs to small compact pustules. Shrubs may be aggregations of simple conidiophores or a more complex reticulum arising from a single stipe and are up to 0.5 mm diam. Pustules are usually transparent under a 10× objective, only <italic>T. viridescens</italic> s.str. forms nearly opaque pustules.</p><p>All three conidiophore types circumscribed by <xref rid="R19" ref-type="bibr">Jaklitsch et al.

This structure of pustules is also typical of <italic>T. stilbohypoxyli</italic>, but that species does not form submoniliform branches. The dense central clusters usually contain ‘type 1’ conidiophores, which are typical of peripheral conidiophores of <italic>T. viride</italic>. They are characterised by highly irregular, unpaired and sinuous branches and typically do not have a well-defined main axis. Conidiophores of shrubs and at the periphery of pustules belong to ‘type 2’ or ‘type 3’. They are characterised by a more or less readily discernable, well-developed main axis, from which lateral branches arise at or near 90°; the lateral branches are longer with distance from the tip and secondary branches, i.e. those arising from the lateral branches are shorter with distance from the point of departure of the branch from the main axis. Branches arise in pairs at the upper levels and often asymmetrically near the base. Phialides tend to terminate branches in more or less cruciate whorls of 3–4. The phialides are mostly straight, cylindrical or somewhat swollen at or slightly above or below the middle. The ‘type 3’ (‘eidamia’-) conidiophore is a variant of ‘type 2’ and differs from it basically by the production of percurrently proliferating phialides, and a more variable branching system. In ‘type 3’ conidiophores branches may be distinctly inclined upwards. In their extreme form they produce irregularly swollen, subglobose cells in the centre of old pustules on CMD and PDA, particularly in the subclades V7 (<italic>T. trixiae</italic>), V8 (<italic>T. viridialbum</italic>) and V10a (<italic>T. nothescens</italic>). The ‘type 3’ conidiophore occurs also in other species of the section, including <italic>T. vinosum</italic>, <italic>T. gamsii</italic> and <italic>T. neokoningii</italic>. In some clades of the <italic>T. viridescens</italic> species complex, however, particularly V3, V4, V5, V9, V9a and sometimes in V10, this morphology is reduced and often only one or two cells below the terminal phialide are enlarged. Conidiophores of Clade V3 deviate from typical conidiophores by rather steeply ascending and mostly unpaired side branches. Clade V8 lacks a distinct main axis generally. Phialides are lageniform and vary little. Conidia of the <italic>T. viridescens</italic> species complex show a rather uniform size range, but have marked tendencies regarding their shape: while conidia in V4, V8, V9, V9a, V10a and V11 are mostly subglobose, those of V1, V2, V5 and V10 are mostly ellipsoidal, and those of V3 and V7 are varying between these shapes.</p></sec><sec id="s3d"><title>Pigments on CMD</title><p>While no pigment is noted on SNA and on PDA pigment formation is usually indistinct in the <italic>T. viridescens</italic> species complex, conspicuous formation of diffusing pigment has been noted on CMD, particularly after prolonged storage of plates at 15 °C. This trait has not been recorded for all species, but the following observations are evident: Clade V1 (<italic>T. olivascens</italic>) consistently produced a (yellowish-, greyish- or brownish-)olivaceous pigment after several months, while Clades V4 (<italic>T. paraviridescens</italic>) and V11 consistently formed a rich yellow pigment. A similar pigment is sometimes formed in CMD agar in V3 and V10 and also by other species of the section, most notably <italic>T. petersenii</italic>.</p></sec><sec id="s3e"><title>Growth rates</title><p>All species of the <italic>T. viridescens</italic> species complex have their optimal growth temperature at 25 °C and typically a marked decrease in growth rate at 30 °C. None of these species grows at 35 °C. Strains of the <italic>T. viridescens</italic> complex fall into two groups defined by their growth rates, and there is little overlap between the groups. After 72 h on PDA at 25 °C, the colony radius of members of the fast-growing group (V1–V4, V7–10 and V10a) is (25−)30–40(−45) mm with V1 and V9a being at the lower end of this range, while the colony radius of members of the slow-growing group (V5 and V11) was only 15–20(−25) mm. A clear difference in growth rates was also noted within the first group between the clades V9 and V9a that reached a growth radius of 40–45 mm vs 25–35 mm, respectively, under the conditions given above. Differences in the colony radius after 3 d were somewhat more striking at 30 °C on Difco-PDA: < 20 mm in the clades V1, V2, V3, V7, V9a and V10a, and > 20 mm in V8, V9 and V10.</p></sec><sec id="s3f"><title>Biogeography and ecology</title><p><italic>Trichoderma viridescens</italic> sensu <xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref> is one of the most common species of the genus <italic>Trichoderma</italic> in Europe. However, only southern Europe and the Canary Islands have been screened sufficiently to reach a more or less representative sampling that includes collection of asexual colonies from plant material. Diversity data from other parts of Europe are mostly based on sexual morph material (<xref rid="R19" ref-type="bibr">Jaklitsch et al. 2006</xref>, <xref rid="R16" ref-type="bibr">Jaklitsch 2011</xref>) and no intensive collection of asexual morphs has been undertaken. Material from other regions has been gathered randomly and does therefore not form a basis for sound interpretation. In southern Europe more than 100 mostly asexual morph specimens of the <italic>T. viridescens</italic> species complex have been gathered, amounting to c. 16 % of all specimens of the genus collected there. All clades of the <italic>T. viridescens</italic> species complex occur in Europe except V6, V9, V9a and V10a. V6 is only known from Peru, V9 from eastern USA, V9a from Taiwan, and V10a from south-eastern Australia. Clade V5 is only known from southern Europe except for one strain from Guatemala (DAOM 234234), which is associated with this clade. The commonest species of the <italic>T. viridescens</italic> species complex in Europe are V1 (<italic>T. olivascens</italic>), V4 (<italic>T. paraviridescens</italic>) and V2 (<italic>T. viridescens</italic>), followed by V3, V5 and V8. These species have been occasionally collected in other continents and may be cosmopolitan, particularly in temperate to subtropical climates. V11 is only known from elevations above 700 m in Crete, Greece.</p><p>Ecologically, species of this clade do not differ from others in sect. <italic>Trichoderma</italic>, but are also similar to members of other clades of the genus. Most specimens have been obtained from dead wood and bark of broad-leaved trees and on fungi growing on them, sometimes conifers, less commonly on bamboos, other plant material, e.g. apples, few as endophytes from deciduous trees, notably <italic>Fagus</italic>, few from mushroom compost and some from drinking water or soil. The highest numbers of isolates from soil are found in the clades V4 and V8, and the small clade V6 only contains strains from soil. Endophytes have been found in V1 and V4. Isolates from drinking water belong to the clades V4 and V8, those from compost or cardboard only represent V10, those from bamboo belong to V1 and V2. Clade V7 seems to prefer coniferous trees. Sexual and asexual morphs that have been found to grow directly on fungi of various kind (basidiomycetes, disco- and pyrenomycetous ascomycetes) belong mainly to V1 (e.g. on <italic>Anthostoma</italic>, <italic>Biscogniauxia</italic>, <italic>Ganoderma</italic>, <italic>Hymenochaete</italic>, <italic>Melogramma</italic>, <italic>Steccherinum</italic>, <italic>Stereum</italic>, <italic>Terana</italic> and other corticiaceous fungi) and V4 (e.g. on <italic>Datronia</italic>, <italic>Rhytidhysteron</italic>).

Drying of stromata is typically associated with a distinct change from pale orange-brown to dark red-brown. The asexual morph in nature is white to dark green, effuse to pulvinate, only rarely forming sulphur-yellow spots. Conidial pustules on CMD are dense, but less compact than in <italic>T. viridescens</italic> s.str. (as exemplified by strain S452).

See <xref ref-type="table" rid="T1">Table 1</xref> for additional strains.</p><p>Notes — <italic>Trichoderma paraviridescens</italic> is the commonest species of the <italic>T. viridescens</italic> complex in Europe. In nature stromata or green asexual morphs are often accompanied by sulphur yellow mycelium that may sometimes be thickly pulvinate. Asexual morph colonies in nature are typically effuse and up to 1 cm long and to 3 mm thick. Also in CMD culture the conidiation is typically only effuse. At most, the conidiophores can form shrubs while somewhat larger, flat pustules develop only rarely and only after c. 2 wk. Conidia of <italic>T. paraviridescens</italic> are more subglobose and more distinctly warted than in <italic>T. viridescens</italic> s.str. Storage of CMD cultures at 15 °C, monitored for 10–22 mo, resulted in distinct warm yellow pigment diffusing through the entire agar. It is nearly as intense as in <italic>T. petersenii</italic>.

(2006)</xref> accommodated phylogenetically diverse taxa. With only one molecular marker and an apparent paucity of phenotypic characters, <xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref> did not divide that clade taxonomically. In the present work we have re-evaluated the taxonomy of the Large <italic>Viridescens</italic> Clade by including many more strains and by adding additional molecular markers, thus adopting the Genealogical Concordance Phylogenetic Species Recognition approach (GCPSR, <xref rid="R40" ref-type="bibr">Taylor et al. 2000</xref>). With the exceptions of <italic>T. virilente</italic> (clade V5) and <italic>Trichoderma</italic> sp. (clade V6), which were not included in the original study of <xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref>, the clades revealed by GCPSR conform exactly to those delimited by <italic>tef1</italic>, confirming once again (see e.g. <xref rid="R31" ref-type="bibr">Samuels et al. 2012</xref>) the utility of this marker in tracking phylogeny and species recognition in <italic>Trichoderma.</italic> However, the 12 species accepted here are difficult to delimit and recognise on the basis of their morphological characters. Species are defined as complex cocktails of traits. Although there are differences, most notably in pigment formation, growth rates, conidial shape and conidiophore structure, the phenotypic characters overlap to such an extent that it is unlikely that they will enable one to determine species in this complex. We therefore refrain from providing a determinative key. A certain identification is provided only by <italic>tef1</italic> sequences, ideally in alignments with other species of the clade and ideally in combination with <italic>rpb2</italic> and/or <italic>acl1</italic> sequences, which should be always determined, if a new species in this clade is to be recognized.</p><p>For the first time we tested <italic>acl1</italic> in <italic>Trichoderma</italic> phylogenetics. Sequences of this marker are easily obtainable and well suitable for this task. The number of parsimony informative sites (151 vs 176 in <italic>rpb2</italic> and 209 in <italic>tef1</italic>) and thus the phylogenetic resolution obtained using this marker is comparable to <italic>rpb2</italic> and <italic>tef1</italic> and superior to other markers recently used in <italic>Trichoderma</italic>, such as <italic>cal1</italic> and <italic>chi18-5</italic> (<xref rid="R6" ref-type="bibr">Druzhinina et al. 2012</xref>, <xref rid="R18" ref-type="bibr">Jaklitsch et al. 2008</xref>). <italic>Acl1</italic> is also promising for other clades of <italic>Trichoderma</italic>. Unlike <italic>rpb2</italic>, of which no intron is used in phylogenetic analyses, but similar to <italic>tef1</italic> introns, parts of <italic>acl1</italic> are highly variable (unpubl. data), which suggest that this marker is useful for resolving fine-tuned taxonomic units within species complexes of the larger clades of <italic>Trichoderma</italic>, rather than in an overall phylogeny of the genus.</p><sec id="s4a"><title>Earlier publications on the Trichoderma viridescens species complex</title><p><xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref> erred in linking <italic>Hypocrea viridescens</italic> to the asexual morph <italic>T. viridescens</italic> s.str. The latter name was based on <italic>Eidamia viridescens</italic> and is supported by the authentic strain CBS 433.34 (dried culture specimen CBS H-7868). <italic>Hypocrea viridescens</italic> and CBS 433.34, however, fall in different phylogenetic subclades of the <italic>T. viridescens</italic> species complex. In the current work clade V2 is recognised as <italic>T. viridescens</italic> s.str. based on strain CBS 433.34, here epitypified with strain CBS 132573 (= S452). The holotype of <italic>H. viridescens</italic> resides in clade V4 and its epithet cannot be combined in <italic>Trichoderma</italic>. Therefore the new name <italic>T. paraviridescens</italic> was given for members of clade V4. The ex-type strain of <italic>H. viridescens</italic> (Hypo 372 = CBS 119321 = C.P.K. 2140) cannot serve as the epitype of <italic>T. viridescens</italic>, and the epitypification of <italic>T. viridescens</italic> by <xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref> is cancelled herewith.</p><p>The description and illustrations by <xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref> of <italic>Hypocrea viridescens</italic>/<italic>Trichoderma viridescens</italic> comprised several species. For this reason, an emended description of <italic>T. viridescens</italic> s.str. (clade V2) is given above.</p><p>Some clades that were not formally established in <xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref> are re-assessed: Clade Vd 1 included two isolates from Sri Lanka and Ghana that have ellipsoidal, warted conidia and lack an eidamia-like morphology. These isolates cluster together again (see <xref ref-type="fig" rid="F1">Fig. 1</xref>), but show long branches, which suggest single lineages rather than a well-defined clade.</p><p><xref rid="R20" ref-type="bibr">Jaklitsch et al. (2012)</xref> described <italic>T. samuelsii</italic> and reported four collections that belong to this species. In addition to these, strains included by <xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref> as <italic>Trichoderma</italic> Vd 2 are also <italic>T. samuelsii</italic>, including J.B. NZ151 (<italic>tef1</italic> accession DQ845422), J.B. PER23 (<italic>tef1</italic> accession DQ845423), C.P.K. 1488 (= UNISS 4-15, from Sardinian soil, <italic>tef1</italic> accession DQ845416) and G.J.S. 05-186 (<italic>tef1</italic> accession DQ841713). They are currently labelled <italic>Trichoderma viride</italic> or <italic>Hypocrea rufa</italic> in GenBank. However, the <italic>tef1</italic> accession DQ845429 given by <xref rid="R19" ref-type="bibr">Jaklitsch et al. (2006)</xref> in <xref ref-type="table" rid="T1">Table 1</xref> for the strain C.P.K. 2071 (a duplicate of C.P.K. 1488) represents in fact <italic>T. gamsii</italic> and is currently labelled in GenBank <italic>Trichoderma</italic> sp. MKZ-2006 strain JB RSA75, while the accession DQ845430 erroneously given for J.B. RSA75 in that table represents <italic>T. viride</italic> strain J.B. NSW13, as given in the same table and correctly included in GenBank.</p><p>Clade Vd3 of <xref rid="R19" ref-type="bibr">Jaklitsch et al.

This clade is situated outside the clade of the <italic>T. viridescens</italic> species complex, close to <italic>T. dingleyae</italic> and comprises the four strains VI03925, VI03967, VI03968, VI03945 (<xref ref-type="fig" rid="F1">Fig. 1</xref>) and probably also VI03960 (<italic>tef1</italic> accession AM498524; <xref rid="R9" ref-type="bibr">Hageskal et al. 2008</xref>).</p></sec></sec></body><back><ack><p>We thank Begoña Aguirre-Hudson, Esperanza Beltran-Tejera, Liliana Bernardo, Marco Contu, Rose Marie Dähncke, Walter Gams, Quirico Migheli, Neven Matocec, Ivana Kušan, Barbara Scherm, Olga Sükösd and Luis Quijada for excursion support; Trix Merkx and Gerard Verkley (CBS) for patience with our cultures and Anton Hausknecht for insertion of specimens into WU.
