description
Description. Asexual morphology: Mycelium superficial and immersed, composed of septate, branched, hyaline to subhyaline, smooth to verruculose hyphae, nodulose, 2 - 5.7 μm wide. Conidiophores macronematous and micronematous, arising laterally or terminally from hyphae, (sometimes reduced to conidiogenous cells), septate, slightly flexuous, non-nodulose, usually unbranched or branched, up to 243 μm long, 2 - 4 μm wide, pale brown, verruculose to verrucose. Conidiogenous cells integrated, terminal and intercalary, cylindrical to subcylindrical, 20.5 - 47.7 x 2 - 3.6 μm, bearing up to four slightly darkened and refractive conidiogenous loci. Ramoconidia 0 - 1 (- 2) - septate, subcylindrical to cylindrical, 10.2 - 28.171 x 2.4 - 4.1 μm [av. (+ / - SD) 17.3 (+ / - 2.39) x 2.9 (+ / - 0.37)], pale brown, verruculose. Conidia forming branched chains, with up to five conidia in the terminal unbranched part, long neck area between conidia, aseptate, pale brown, smooth to verruculose, with protuberant, slightly darkened and refractive hila. Small terminal conidia aseptate, obovoidal to ellipsoidal, 2.9 - 5.3 x 2 - 3 μm [av. (+ / - SD) 3.8 (+ / - 0.53) x 2.5 (+ / - 0.25)]. Intercalary conidia aseptate, very rarely 1 - septate, ellipsoidal to limoniform, obovoid, sometimes subcylindrical, 2.7 - 6.2 x 1.8 - 2.8 μm [av. (+ / - SD) 4.2 (+ / - 0.76) x 2.3 (+ / - 0.22)]. Secondary ramoconidia 0 - 1 - septate, subcylindrical to cylindrical, slightly obclavate, 8.5 - 28.2 x 2.3 - 3.7 μm [av. (+ / - SD) 14.5 (+ / - 4.38) x 2.9 (+ / - 0.35)]. Cultural characters: Colonies on PDA 37 - 66 mm diam after 14 d at 25 ° C, olive (3 E 3 to 3 F 4), reverse dark gray (1 F 1), floccose-velvety, sometimes woolly, raised, radially furrowed, wrinkled, raised; margin white, slightly hyaline edge, undulated; aerial mycelia abundantly formed, with numerous prominent exudates, sporulation profuse. Colonies on MEA 35 - 40 mm diam after 14 d at 25 ° C, grayish white (1 B 1) to olive gray (3 D 2), reverse dark gray (1 F 1), velvety, raised to crateriform, radially furrowed at the margin region, wrinkled; margin white, regular; aerial mycelia abundantly formed, dense, without prominent exudates, sporulation profuse. Colonies on OA 41 - 47 mm diam after 14 d at 25 ° C, gray (1 C 1 to 1 E 1), reverse concolorous, velvety, floccose, raised, radially furrowed; margin yellowish, regular; aerial mycelia abundantly formed, with few exudates, sporulation profuse. Colonies on SNA 37 - 41 mm diam after 14 d at 25 ° C, olive (3 D 3) to olive yellow (3 E 8), reverse olive (3 D 3 to 3 F 3), slightly fluffy-floccose, powdery, flat; margin yellowish white (2 A 2), hyaline, undulate; aerial mycelia abundantly moderate, without prominent exudates, sporulation profuse.
