A revision of Linodochium, Pseudocenangium, Septopatella, and Siroscyphella

Abstract

Pseudocenangium Karst. is redescribed and illustrated, and Siroscyphella Höhn. is reduced to synonymy with it. Two species, P. pinastri and P. succinenm, are accepted. Septopatella Petrak, based on P. septatum, is confirmed as a distinct form genus. Pseudocenangium hartigianum and P. umense are made the types of the new form genera Gelatinopycnis and Pocillopycnis respectively. Pseudocenangium laricinum is excluded. The related form genus Linodochium hyalinum (Lib.) Höhn. is redescribed and illustrated.
