Sochorová Z., Eckstein J., Sedlár?ová M. & Sochor M. (2021) Octospora doebbeleri, a new bryophilous species on Dicranoweisia 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.
