Odour sweet or bitter-sweet, powerful in recently isolated cultures, disappearing in old cultures. Aerial mycelium scanty to abundant, cottony, to 7 mm higher or 2mm in cultures generating teleomorph; mostly 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 suitable angles, not differentiated from these or distinct with key axis yellowish ochraceous, KOH+ and wall slightly thickened; ascending to suberect, 20000(000) m extended, primary axis close to base 40 m wide; PD 151746 chemical information branching profuse or in some cases sparse, verticillate or irregular, sometimes drepanoid, broadly distributed, at times confined to uppermost parts, conidiophores then appearing irregularly tree-like in aspect; lateral branches formed at 1 levels, 1 establishing from one particular point, 300 3.five.five m. Conidiogenous cells formed directly on conidiophores or from lateral branches that happen to be typically integrated within a earlier verticil of conidiogenous cells, building singly or (23() within a verticil, occasionally singly beneath verticil; subulate, 250 m lengthy, 2.5.5 m wide close to base, attenuating progressively to 0.eight.0 m at apex; aseptate; forming a single conidiogenous locus at apex. Conidiaellipsoidal to fusiform, long obovoid i.e. droplet-shaped or at times widest in lower half (oblong-ovoid); equi- or inequilateral, straight but in some cases with basal or each ends curved; attenuated at base to a narrow but prominent central hilum, typically attenuated also at apex; (9.511.72.2(six.five) (four.05.four.two (.0) m, Q = (1.62.two.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 produced 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 after which observed growing on bark, wood or connected with other ascomycetes.
