Culture. N . Conidiophores with verticillately placed conidiogenous cells bearing conidia at their guidelines. 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 fast, 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, powerful in lately isolated cultures, disappearing in old cultures. Aerial mycelium scanty to abundant, cottony, to 7 mm high or 2mm in cultures producing Anemoside B4 teleomorph; largely homogenous, sometimes with tufts; yellowish white, amber or buff, partially turning violet in KOH. Submerged hyphae frequently 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 suitable angles, not differentiated from these or distinct with most important axis yellowish ochraceous, KOH+ and wall slightly thickened; ascending to suberect, 20000(000) m long, principal axis close to base 40 m wide; branching profuse or sometimes sparse, verticillate or irregular, sometimes drepanoid, extensively distributed, sometimes confined to uppermost parts, conidiophores then appearing irregularly tree-like in aspect; lateral branches formed at 1 levels, 1 creating from one particular point, 300 three.five.five m. Conidiogenous cells formed straight on conidiophores or from lateral branches which are generally integrated within a preceding verticil of conidiogenous cells, developing singly or (23() in a verticil, often singly below verticil; subulate, 250 m lengthy, 2.5.five m wide close to base, attenuating gradually to 0.eight.0 m at apex; aseptate; forming 1 conidiogenous locus at apex. Conidiaellipsoidal to fusiform, lengthy obovoid i.e. droplet-shaped or in some cases widest in decrease half (oblong-ovoid); equi- or inequilateral, straight but at times with basal or both ends curved; attenuated at base to a narrow but prominent central hilum, often attenuated also at apex; (9.511.72.2(six.five) (4.05.4.2 (.0) m, Q = (1.62.2.8(.6); 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 in some cases 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; two 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 numerous wood-decaying members of Agaricales, Hymenochaetales and Polyporales, also on Auriculariales; in some collections host fungus not detected and after that observed expanding on bark, wood or associated with other ascomycetes. Distribution: Tropical America. Holotype: Puerto Rico, Luquillo, Chicken Farm, on.
