Culture. N . Conidiophores with verticillately placed conidiogenous cells bearing conidia at their ideas. R . Conidia. U. Hyphae turning from initial yellow to purple in KOH. V, W. Chlamydospores.

Scale bars: A = 1 cm; B, C = 500 m; D, K, L = 250 m; E, O = 100 m; F, H = 50 m; G, M, N, P, Q, U = 20 m; PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21261711 I, J, R , V, W = ten m. www.studiesinmycology.orgP dMaa Colonies on MEA spreading quickly, reaching 450 mm in 4 d; margin even or slightly fasciculate; reverse initially yellow, turning purplish red; yellowish brown, round or fan-shaped crystals and or pigment patches with needle-like margins, turning deep purple in KOH, abundant in agar. 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, sometimes with tufts; yellowish white, amber or buff, partially turning violet in KOH. Submerged hyphae usually 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 near base 40 m wide; branching profuse or sometimes sparse, verticillate or irregular, occasionally drepanoid, extensively 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.five.5 m. Conidiogenous cells formed straight on conidiophores or from lateral branches that are normally integrated in a previous verticil of conidiogenous cells, building singly or (23() within a verticil, in some cases singly below verticil; subulate, 250 m long, 2.five.5 m wide near base, attenuating progressively to 0.8.0 m at apex; aseptate; forming one conidiogenous locus at apex. Conidiaellipsoidal to fusiform, extended obovoid i.e. droplet-shaped or at times 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) (4.05.4.2 (.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 STF-62247 web 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 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 developing on bark, wood or connected with other ascomycetes. Distribution: Tropical America. Holotype: Puerto Rico, Luquillo, Chicken Farm, on.
