 Description: Colonies growing slighty fast on Potato Dextrose Agar at 25℃, plane, villose, dark brown to blackish-brown, reverse pale brown to light coffee brown, with distinct diffused vinaceous pigment. Mycelium partly immersed, composed of branched, septate, thin-walled, hyaline to light brown and septae darker, smooth or finely verruculose hyphae, 2 – 5 μm wide. Conidiophores macronematous or semimacronematous, arising from submerged or aerial hyphae, simple or branched in lower part, mostly twice-branched, light brown, paler lighter at tip, smooth to finely rough, 3 -4 septae, 39 – 53.5 × 2.5 – 3 μm. Conidiogenous cells terminal, smooth to finely rough, pale brown to hyaline, elongate-ampulliform, collarette funnel-shaped, inconspicuous, 16 – 27.5 × 3 – 4 μm. Conidia hyaline, smooth, ellipsoidal to allantoid, aggregated in slimy head, 3 – 5 × 1.6 – 2 μm.

 Note: Morphologically Phaeoacremonium rubrigenum isolated from Taiwan mostly resembled to the original described species by Gams et al (1996), nevertheless, the character of the hyphae were not conspicuously tuberculate or verruculose. Also in aged colony the reverse color of our isolate showed distinct brown coloration in contrast to the wine red described by Gams et al (1996).
