New species of Octospora and some further remarkable bryoparasitic Pezizales from the Netherlands

This article presents an overview of remarkable findings of bryoparasitic Pezizales in the Netherlands collected in the period 1995-2002. These collections provide further insight into the distribution, ecology, morphology and host relationships of the species described, some of which represent unknown taxa. Three new species are described, primarily or exclusively based on collections from the Netherlands: Octospora neerlandica, O. fissidentis and O. nemoralis. The following connections with host-mosses were observed: Tortula ruralis s. str., T. ruraliformis, T. virescens with O. neerlandica, and Fissidens bryoides with O. fissidentis as well as O. nemoralis. As a result of the intensive field survey, the number of species known from the Netherlands has increased from 14 to 40. This indicates that current knowledge on the distribution of bryoparasitic Pezizales is very incomplete in many countries.
