general taxon notes:

 

There are about 30 species of Pleuridium in the world. Most of the species in the genus are distributed in the temperate regions. One species is known from China. The species most easily confused with Pleuridium is Eccremidium brisbanicum (Broth.) Stone & Scott, which was recently reported from Hong Kong (L. Zhang et al. 1998). However, we could not confirm this report.
