Four bryoparasitic ascomycetes, Lamprospora tuberculata, Octospora ithacaensis, O. orthotrichi and O. affinis were recently found in the Czech Republic for the first time. For each species, basic description of macroscopical and microscopical characters, information about its habitat, distinguishing features of similar species as well as notes on the distribution in Europe are provided. Furthermore, apothecia, spores and parasitising structures are illustrated. The following parasite-host relationships were observed: L. tuberculata on Pleuridium subulatum, O. ithacaensis on Marchantia polymorpha, O. orthotrichi on Orthotrichum diaphanum and O. affinis on Orthotrichum affine.One locality of L. tuberculata, two of O. ithacaensis, eight of O. orthotrichi and one of O. affinis were found. Internal cavities in the warts of spores in O. affinis and L. tuberculata are newly reported as well as the infection of leaf cells in O. affinis.
