Scens K. P dmaa, sp. nov. MycoBank MB518512. Figs 4L, 13.Etymology: refers to the similarity towards the anamorph of H. virescens although phylogenetically not closely related.In MEA substratum, conidiophora 30000 m longa, prope basin six m lata. Cellulae conidiogenae subulatae, cum unum vel paucos conidiogenos locos, 255 m longae, prope basin four.0.0 m latae. Conidia ellipsoidea, interdum clavatae, (18.022.5(7.5) (six.58.three(0.0) m, basi attenuata, saepe curva in dimidio inferiore, 1()-septata, hyalina vel diluta flavovirentes; 2() conidia ad apicem cellulae conidiogenae. Chlamydosporae sublgobosae, 147 124 m, hyalinae vel ochraceae, catenatae; structurae aggregatae similes sclerotiis fuliginosae, pseudoparenchymatae.Colonies on MEA spreading rapidly, reaching 70 mm in four d; reverse first ochraceous or yellow turning crimson; margin even. Odour absent. Aerial mycelium moderate, cottony, up to 4 mm high, reaching lid of Petri dish at margin; buff, acquiring greenish tinge with formation of conidia, hyphae turning purple in KOH. Submerged hyphae normally turning purple in KOH, cells infrequently becoming swollen. Conidiation abundant, often in patches. Conidiophores not differentiated from aerial hyphae; ascending to suberect or erect, primary axis 30000 m lengthy, 6 m wide, thin-walled, brownish yellow, except at apex, pigmented components turning purple in KOH; branching PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21258100 moderate to profuse, verticillate or irregular, often drepanoid, order PI4KIIIbeta-IN-10 mainly in uppermost aspect; conidiophores frequently borne as side branches from a verticil of conidiogenous cells, further branching at apex; lateral branches supporting 1 conidiogenous cells, 255 m extended and four.0.0 m wide,generally integrated into a previously formed verticil. Conidiogenous cells3() within a verticil; subulate, 300 m extended, three.five m wide near base, attenuating to 0.7.three m at apex; aseptate, forming one conidiogenous locus at tip or occasionally an extra locus on a smaller protrusion inside the middle of cell or ca. three m from tip. Conidia ellipsoidal, some slightly clavate, mainly inequi some equilateral, straight or curved in 
lower half, mainly attenuated towards base; (18.022.5(27.five) (six.58.three(0.0) m, Q = (2.22.7(.three); 1()-septate, septum median or from time to time sub- or supramedian; hyaline or pale yellowish green, pale green in conidial masses in culture; hilum prominent, narrow, refractive, central or laterally placed; conidia formed obliquely from uppermost locus, held by two() in radiating heads. Chlamydospores formed among submerged mycelium, cells subglobose, 147 124.five m, wall 0.7 thick, hyaline to pale ochraceous, in intercalary or lateral chains; dark brown sclerotia-like aggregations scattered above agar, to 1 mm diam, homogenous, pseudoparenchymatous, cells 139 124 m, with wall 1.0.three thick, yellowish ochraceous. Substrata: Aphyllophoralean basidiomycete. Distribution: Southeastern Asia, recognized only from the form locality. Holotype: Thailand, Khao Yai National Park, Nature trail km 33 to Nong Pak Chi, on an aphyllophoralean basidiomycete, 1 Aug. 1997, K. P dmaa, TAAM 169726, ex-type culture TFC 97-23 = CBS 100366. Notes: Cladobotryum paravirescens is distinct in creating yellowish green, mainly 1-septate conidia with acuminate bases which might be usually curved. The colouration of conidia, led for the original identification of these two Thai collections as C. virescens (P dmaa Samuels 2004), previously the only recognized species producing redRed-PigMented tRoPical HypomycesFig.13.Cladobotryum paravirescens, ex-type culture TFC 97-23 on MEA.
