Three new hypocrealean ascomycetes on bryophytes

Döbbeler P. (2005). Three new hypocrealean ascomycetes on bryophytes.

Sydowia 57 (2): 179-188.

The following bryophilous species of the order Hypocreales (Ascomycetes) are described as new: Bryonectria tricellularis grows biotrophically on Frullania dilatata . It is apparently rare and only recorded from the type collection in Romania. Nectria hyperepiphylla is a biotrophic parasite on an epiphyllous hepatic in New Caledonia. Apart from ascoma anatomy the species is characterized by elaborate infecting structures consisting of appressoria and intracellular haustoria. The necrotrophic Nectria voratella causes discolourations on different mosses in Italy and France. The species are illustrated in detail in order to facilitate their recognition and identification.
