Morphological description
Asexual morph:CYA 25 ◦C 7 d: Colonies 22–25 mm diam, thin, radially plicate slightly, margins submerged, fimbriate; colony texture velutinous and granular due to limited gymnothecia,Pinard yellow (R.

I), Strawberry pink (R. Pl. I) at margins. MEA 25 ◦C 7 d: Colonies 48–51 mm diam, thin, plane, margins submerged, regular; colony texture granular due to abundant gymnothecia, Green-yellow (R. Pl. V); sporulation absent or limited, conidia en masse Olive-gray (R. Pl. LI); mycelium Green-yellow (R. Pl. V), white at margins; exudate and soluble pigment absent; reverse light Danube green (R. Pl. XXXII) centrally while Cinnamon buff (R. Pl. XXIX) at peripheries. YES 25 ◦C 7 d: Colonies 25–28 mm diam, thin, radially sulcate, margins on agar surface, fimbriate; colony texture velutinous and granular due to limited gymnothecia at centers, Pinard yellow (R. Pl. IV); sporulation absent or sparse, conidia en masse Light olive gray (R. Pl. LI); mycelium Pecan brown to Cacao brown (R. Pl. XXVIII), white at margins; exudate and soluble pigment absent; reverse Morocco red (R. Pl. I), Moral red (R. Pl. I) at margins. OA 25 ◦C 7 d: Colonies 33–35 mm diam,thin, plane, mostly submerged; colony texture slimy and sparsely granular due to limited gymnothecia in centers, Light greenish yellow (R. Pl.
