Description.

Mycelium consisting of branched, septate, hyaline, smooth hyphae. Aerial conidiophores unbranched or branched, hyaline, bearing terminal and lateral conidiogenous cells, or reduced to single conidiogenous cells borne laterally or terminally on aerial hyphae. Conidiogenous cells monophialidic, subcylindrical, cylindrical or slightly subulate, hyaline, often with a conspicuous flared collarettes, without noticeable periclinal thickening. Microconidia ellipsoidal, cylindrical, slightly reniform or obovoid, hyaline, smooth, aseptate or septate.

Sporodochial conidiogenous cells monophialidic, slightly subulate to subcylindrical, hyaline, collarettes absent or inconspicuous, without noticeable periclinal thickening. Sporodochial macroconidia falcate, slightly curved to curved with parallel walls, regularly wide along almost the entire length, tapering in apical cell toward the apex (rarely tapering towards both ends), apical cell slightly curved to curved, basal cell obtuse, non foot-shaped, aseptate or septate, hyaline, smooth.
