Culture. N . Conidiophores with verticillately placed conidiogenous cells bearing conidia at their suggestions. R . Conidia. U. Hyphae turning from initial yellow to purple in KOH. V, W. Chlamydospores. (A, H, I. TU 112902; B, G, J. BPI 749247; C, K. TFC 97-138; D, E. Holotype, BPI 748258; F. TU 112903; L, M. TU 112901; N, S, V. TFC 00-30; O . TFC 200789; R, U. Ex-type culture, G.J.S. 98-28; T, W. G.J.S. 96-41). Scale bars: A = 1 cm; B, C = 500 m; D, K, L = 250 m; E, O = one hundred 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 speedy, reaching 450 mm in four 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, sturdy in not too long ago isolated cultures, disappearing in old cultures. Aerial mycelium scanty to abundant, cottony, to 7 mm higher or 2mm in Imazamox cultures producing teleomorph; mainly homogenous, occasionally 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 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, primary axis close to base 40 m wide; branching profuse or sometimes sparse, verticillate or irregular, sometimes drepanoid, broadly distributed, sometimes confined to uppermost parts, conidiophores then appearing irregularly tree-like in aspect; lateral branches formed at 1 levels, 1 developing from a single point, 300 three.five.five m. Conidiogenous cells formed straight on conidiophores or from lateral branches which can be frequently integrated inside a previous verticil of conidiogenous cells, building singly or (23() in a verticil, often singly beneath verticil; subulate, 250 m extended, two.five.five m wide near base, attenuating progressively to 0.eight.0 m at apex; aseptate; forming a single conidiogenous locus at apex. Conidiaellipsoidal to fusiform, extended 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 both ends curved; attenuated at base to a narrow but prominent central hilum, generally attenuated also at apex; (9.511.72.two(6.5) (four.05.4.2 (.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 at times 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 made in abundance in current cultures isolated from ascospores. Substrata: Basidiomata of many wood-decaying members of Agaricales, Hymenochaetales and Polyporales, also on Auriculariales; in some collections host fungus not detected then observed expanding on bark, wood or connected with other ascomycetes. Distribution: Tropical America. Holotype: Puerto Rico, Luquillo, Chicken Farm, on.
