Lichenostigma aff. elongatum a Stigmidium rouxianum, dva druhy lichenikolních hub zjištěných na Acarospora cervina v ČR

Lichenostigma aff. elongatum (Arthoniales) and Stigmidium rouxianum (Dothideales s.l.), two lichenicolous fungi found on a thallus of Acarospora cervina, are reported from the Czech Republic. Both species were recorded on xerothermic rocks in the protected area Pavlovské vrchy hills in the South Moravia. Records of Stigmidium rouxianum are new to the country, Lichenostigma elongatum has only been known from the genera Aspicilia and Lobothallia (Hymeneliaceae) so far. As the genus Lichenostigma generally contains host-specific species, the record from Acarospora (Acarosporaceae) may belong to an unknown cryptic species.
