Description

Saprobic on the surface of decaying wood (Fig. 3 ). Asexual morph: Colonies on natural substratum. Conidial secession schizolytic. Conidia solitary, acropleurogenous, 9-13 μm long (x̅ = 11.0 μm, SD = 1.9, n = 18), 1.9-3.6 μm wide (x̅ = 3.0 μm, SD = 0.6, n = 15), ellipsoidal to obovoidal, rounded at the apex, hyaline, aseptate, guttulate, smooth-walled. Sexual morph: Undetermined.

Etymology

With reference to Guizhou Province where the type specimen was found.

Notes

Phaeoisaria guizhouensis morphologically resembles P. aquatica Z. L. Luo et al. and P. pseudoclematidis D.Q. Dai & K.D. Hyde, but they differ in conidial size (6.5-7.5 × 2.5-3.5 μm for P. aquatic ; 9-13 × 1.9-3.6 μm for P. guizhouensis ; 5-8.5 × 3-4 μm for P. pseudoclematidis ) and the conidial of P. acquatica and P. pseudoclimatidis appears around the conidiophores, but P. guizouensis only appears at the apex ( Liu et al. 2015, Luo et al. 2018).
