Odour sweet or bitter-sweet, sturdy in not too long ago isolated cultures, disappearing in old cultures. Aerial mycelium scanty to abundant, cottony, to 7 mm high or 2mm in cultures producing teleomorph; mostly homogenous, sometimes with tufts; yellowish white, amber or buff, partially turning violet in KOH. Submerged hyphae normally turning violet in KOH, cells infrequently swollen. Conidiation abundant in fresh isolates, becoming moderate to scarce in older strains. Conidiophores arising from aerial hyphae at right angles, not differentiated from these or distinct with main axis yellowish ochraceous, KOH+ and wall slightly thickened; ascending to suberect, 20000(000) m long, key axis close to base 40 m wide; branching profuse or sometimes sparse, verticillate or irregular, occasionally drepanoid, broadly distributed, in some cases confined to uppermost parts, conidiophores then appearing irregularly tree-like in aspect; lateral branches formed at 1 levels, 1 creating from one point, 300 three.five.five m. Conidiogenous cells formed straight on conidiophores or from lateral branches that happen to be typically integrated within a preceding verticil of conidiogenous cells, developing singly or (23() inside a verticil, often singly under verticil; subulate, 250 m extended, two.five.5 m wide close to base, attenuating gradually to 0.8.0 m at apex; aseptate; forming one particular conidiogenous locus at apex. Conidiaellipsoidal to fusiform, lengthy obovoid i.e. droplet-shaped or sometimes widest in decrease half (oblong-ovoid); equi- or inequilateral, straight but from time to time with basal or each ends curved; attenuated at base to a narrow but prominent central hilum, often attenuated also at apex; (9.511.72.two(six.five) (four.05.4.2 (.0) m, Q = (1.62.two.8(.6); 1-septate, in 1-septate conidia septum median or in upper 13 or 23; hyaline or occasionally with tinge of green when old, with refractive thickening at base or at times also at apex; formed obliquely from uppermost locus, held by (12() in imbricate chains appearing as radiating heads. Chlamydospores formed (R,S)-AG-120 web amongst aerial or submerged mycelium, hyaline; cells subglobose, 133 m diam, wall 1 m thick, smooth; 2 cells in intercalary chains or in lateral, irregular chains or sclerotia-like aggregations formed from an intercalary cell. Perithecia developed in abundance in current cultures isolated from ascospores. Substrata: Basidiomata of several wood-decaying members of Agaricales, Hymenochaetales and Polyporales, also on Auriculariales; in some collections host fungus not detected and then observed increasing on bark, wood or related with other ascomycetes.
