Species [1]

Pseudochaete is a genus of green algae, in the family Chaetophoraceae. [1] However, this genus is not recognized by all authorities, sometimes being considered part of genus Stigeoclonium . [2]

The name Pseudochaete, published by T. Wagner & M. Fischer in 2002, is also used for a genus of fungi belonging to the family Hymenochaetaceae and formerly part of genus Hymenochaete described by Léveillé. [3] [4] According to Index Fungorum, the fungus name is illegitimate (and the algal genus has priority) but its use is widespread. [5]

Pseudochaete consists of heterotrichous, uniseriate filaments. The basal part of the thallus is prostrate, from which erect filaments emerge. Prostrate filaments are short, branched, with cells containing a nucleus and a parietal chloroplast with a pyrenoid. Erect filaments are hair-like, five to eight cells long, with cylindrical cells and chloroplast lacking pyrenoids. [1]
