cirrata. – Sydowia 73: 233–244.
Octospora doebbeleri, a new bryophilous species infecting rhizoids of the acrocarpous moss Dicranoweisia cirrata, is described
and illustrated based on collections from the Czech Republic. The delineation of the new species, based on the unique set
of morphological characters, is also supported by phylogenetic analysis of LSU and SSU nrDNA and EF1a. Morphologically,
O. doebbeleri is characterised by apothecia with a thin margin and ellipsoid, mostly binucleate ascospores ornamented with
small isolated warts. Differences from other morphologically similar species of Octospora are discussed.
