　Description： Colonies, diameter on CMA 48-51 mm in 21 d, effuse, sporodochia abundant, yellowish brown to dark brown, scattered in central area, or zonate, 1-3 circles in submargin, up to 400 μm wide. Mycelium mostly submerged, partly superficial, white, grey-white, greyish yellow, composed of branched, septate, smooth, roughened or verrucose, hyaline to brown hyphae, (0.8)1.5-4.0(4.8) μm wide; soluble pigment pale yellow to lightly yellow; reverse colourless, orange yellow to yellowish brown. Conidiophores micronematous, simple, or irregularly branched, straight or flexuous, smooth, roughened or verrucose, hyaline or brown. Conidiogenous cells integrated or discrete, hyaline to brown, cylindrical, doliiform, cuneiform, subglobose, globose, smooth, 3.2-8.7 × 2.8-8.0 μm. Conidia solitary, holoblastic, cheiroid, light reddish or dark brown, smooth, 54-114 × 18-42 μm, with a more or less triangular basal cell on which (4)6-8 parallel, tightly appressed arms arise, flattened in one plane, each arm with up to 24 septa, septa usually constricted, terminal cell distinctly thin-walled, hyaline, digitate, straight, or flexuous, incurved or even curled, total number of conidial cells (57)79-184. On oat meal agar (OMA) sporodochia up to 1000 μm wide.

　Note： The digitate appendages of D. digitatum distinguish it from D. bulbosum and D. alatum Van Emden, the latter two species having bulbous or allantoid, hyaline thin-walled appendages arising from the apical cell of the outer row fo the conidia, respectively (Tzean & Chen, 1989; Van Emden, 1975). The cheiroid conidia of D. digitatum were flattened in one plane and they differ from D. heptosporum (Garovaglio) Damon, in which the arms comprising the conidia are inserted in different planes, though both species showed some similarity in conidial morphology and size, also in the formation of sporodochia. In addition mature conidia of D. heptosporum in water preparations formed fragile, bulbose, hyaline apical ornamentations, but they are absent from dry mounts and thus interpreted as an arti-fact (Rao & De Hoog, 1986).
