Description

Asexual morph: Colonies on natural substratum effused, thin, reddish–brown. Mycelium immersed and superficial, composed of branched, septate, dark, anastomosing hyphae, (5–)7–15(–25) μm in diam. Conidiophores and conidia lacking. Chlamydospores abundant, intercalary, solitary or in chains of 2 to 5, occasionally branched, with 5 to 9 septa, constricted at the septa, fusiform, brown to blackish, 100–450 μm in length, 35–42 μm in width. Sexual morph: In Jahnula. (Descriptions based on Suetrong et al. (2011)).

NOTES: Members of the Aliquandostipitaceae are freshwater ascomycetes, but Xylomyces chlamydosporus was collected by Goos et al. (1977). Sivichai et al. (2011) showed that X. chlamydosporus was the anamorph of Jahnula aquatica but this was not confirmed in a phylogenetic study (Suterong et al. 2011).
