Odour sweet or bitter-sweet, robust 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 creating teleomorph; mostly homogenous, occasionally with tufts; yellowish white, amber or buff, partially turning violet in KOH. Submerged hyphae generally 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 ideal angles, not differentiated from these or distinct with main axis yellowish ochraceous, KOH+ and wall slightly thickened; ascending to suberect, 20000(000) m lengthy, main axis close to base 40 m wide; branching profuse or sometimes sparse, verticillate or irregular, occasionally drepanoid, broadly distributed, at times confined to uppermost parts, conidiophores then appearing irregularly tree-like in aspect; lateral branches formed at 1 levels, 1 creating from a single point, 300 three.5.five m. Conidiogenous cells formed straight on conidiophores or from lateral branches that are normally integrated in a prior verticil of conidiogenous cells, building singly or (23() within a verticil, in some cases singly below verticil; subulate, 250 m lengthy, 2.five.5 m wide close to base, attenuating progressively to 0.8.0 m at apex; aseptate; GDC-0084 forming 1 conidiogenous locus at apex. Conidiaellipsoidal to fusiform, long obovoid i.e. droplet-shaped or from time to time widest in reduced 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, generally attenuated also at apex; (9.511.72.2(6.5) (4.05.four.2 (.0) m, Q = (1.62.two.eight(.six); 1-septate, in 1-septate conidia septum median or in upper 13 or 23; hyaline or sometimes with tinge of green when old, with refractive thickening at base or sometimes also at apex; formed obliquely from uppermost locus, held by (12() in imbricate chains appearing as radiating heads. Chlamydospores formed 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 a variety of wood-decaying members of Agaricales, Hymenochaetales and Polyporales, also on Auriculariales; in some collections host fungus not detected then observed increasing on bark, wood or connected with other ascomycetes. Distribution: Tropical America. Holotype: Puerto Rico, Luquillo, Chicken Farm, on.
