Odour sweet or bitter-sweet, robust in lately isolated cultures, disappearing in old cultures. Aerial mycelium scanty to abundant, cottony, to 7 mm higher or 2mm in cultures producing teleomorph; mainly homogenous, sometimes with tufts; yellowish white, amber or buff, partially turning violet in KOH. Submerged hyphae often 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 proper angles, not differentiated from these or distinct with primary axis yellowish ochraceous, KOH+ and wall slightly thickened; ascending to suberect, 20000(000) m extended, primary axis close to base 40 m wide; branching profuse or from time to time sparse, verticillate or irregular, occasionally drepanoid, extensively distributed, often confined to uppermost parts, conidiophores then appearing irregularly tree-like in aspect; lateral branches formed at 1 levels, 1 building from one point, 300 three.five.5 m. Conidiogenous cells formed straight on conidiophores or from lateral branches that are often integrated inside a previous verticil of conidiogenous cells, building singly or (23() in a verticil, at times singly beneath verticil; subulate, 250 m lengthy, two.5.5 m wide near base, attenuating steadily to 0.eight.0 m at apex; aseptate; forming one conidiogenous locus at apex. Conidiaellipsoidal to fusiform, extended obovoid i.e. droplet-shaped or often widest in reduced half (oblong-ovoid); equi- or inequilateral, straight but occasionally with basal or both ends curved; attenuated at base to a narrow but prominent central hilum, generally attenuated also at apex; (9.511.72.two(six.5) (4.05.4.2 (.0) m, Q = (1.62.2.eight(.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 often also at apex; formed obliquely from uppermost locus, held by (12() in imbricate chains appearing as radiating heads. Chlamydospores formed among 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 created in abundance in recent cultures isolated from ascospores. Substrata: Basidiomata of numerous wood-decaying members of Agaricales, Hymenochaetales and Polyporales, also on Auriculariales; in some collections host fungus not detected and then observed developing on bark, wood or associated with other ascomycetes. Distribution: Tropical America. Holotype: Puerto Rico, Luquillo, Chicken Farm, on.
