　Description： Colonies diameter on V8 Agar 46-50 mm in 25 days at 25°C, effuse, floccose, greyish white to yellowsih grey or middle (4B-E1;4B2); reverse greyish yellow to brownish yellow or greyish orange to brownish orange (4B2-5;5C4-7;5B6). Mycelium partly superficial, partly immersed, composed of branched, occasionally anastomosing, septate, smooth to verrucose, hyaline to pale yellowish brown or brown, 1.3-4.0 μm wide hyphae. Conidio-phores micronematous, semi-macronematous, mononematous, simple or branched, straight to flexuous or sinuous, smooth or verrucose, subhyaline to pale brown, 4.0-23.2 × 2.8-3.8 μm. Conidiogenous cells monoblastic. Conidia elongated-ellipsoidal or small corn-shaped, 19.0-29.0 × 9.6-13.6 μm, smooth, greyish yellow to yellowish brown, thick-walled, con-sisting of a truncate basal cell , on which (3)4 appressed, discrete, vertical arms are rised in different planes; arms straight or slightly curved, 16.0-26.8 × 5.2-6.4 μm, 4-6(7)-septate, often constricted at the septate; apical cells often becoming a hyaline to subhyaline, thin-walled, ellipsoidal, obovoid, or reniform (rarely 1-septate present) appendage, 5.6-9.3 μm wide.

　Note： This species is easily recognized by its smaller, elongated-ellipsoidal or small corn-shaped conidia. However, the Taiwanese isolate resembles the type species of D. micronesicum which was described by Matsushima (1982). The only difference between these two fungi is the Taiwanese fungi has hyaline and elllipsoidal to reniform appendge.
