Odour sweet or bitter-sweet, strong in recently isolated cultures, disappearing in old cultures. Aerial mycelium scanty to abundant, cottony, to 7 mm high or 2mm in cultures producing teleomorph; largely 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 proper angles, not differentiated from these or distinct with key axis yellowish ochraceous, KOH+ and wall slightly thickened; ascending to suberect, 20000(000) m extended, main axis near base 40 m wide; branching profuse or sometimes sparse, verticillate or irregular, sometimes drepanoid, extensively distributed, from time to time confined to uppermost components, conidiophores then appearing irregularly tree-like in aspect; lateral branches formed at 1 23-Hydroxybetulinic acid levels, 1 creating from one particular point, 300 three.5.five m. Conidiogenous cells formed directly on conidiophores or from lateral branches which are usually integrated within a previous verticil of conidiogenous cells, establishing singly or (23() inside a verticil, occasionally singly beneath verticil; subulate, 250 m lengthy, 2.five.5 m wide close to base, attenuating progressively to 0.8.0 m at apex; aseptate; forming one particular conidiogenous locus at apex. Conidiaellipsoidal to fusiform, long obovoid i.e. droplet-shaped or sometimes widest in reduce half (oblong-ovoid); equi- or inequilateral, straight but occasionally 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(6.5) (four.05.four.2 (.0) m, Q = (1.62.two.8(.six); 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 in some cases 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; two cells in intercalary chains or in lateral, irregular chains or sclerotia-like aggregations formed from an intercalary cell. Perithecia produced 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 then observed developing on bark, wood or associated with other ascomycetes. Distribution: Tropical America. Holotype: Puerto Rico, Luquillo, Chicken Farm, on.
