Lentithecium fluviatile (Aptroot & Van Ryck.)

The genus Lentithecium (Lentitheciaceae, Pleosporales) was introduced by Zhang et al. (2009) to accommodate some freshwater fungal members previously placed in Massarina. Lentithecium is characterized by its immersed, lenticular ascomata, a thin peridium, cellular pseudoparaphyses, short pedicellate asci and fusoid or filliform, hyaline, 1- to multi-septate ascospores, usually surrounded by a heath (Zhang et al. 2009).

Species of Lentithecium mostly have a freshwater habitat, and are saprobic. Presently Lentithecium also contains four species that are lignicolous.

Specimens examined: Belgium, East-Flanders, Tielrode tidal marsh near river Schelde, on Phragmites australis, 10 Apr. 2000, Van Ryckegem 509, holotype GENT, isotype CBS-H. France, Populus sp., 23 Nov. 2006, M. Delmont, CBS 122367.
