VĚZDA A. (1969): Beiträge zur Kenntnis der flechtenbewohnenden Pilze in der Tschechoslowakei. II.- Zwei neue Arten: Opegrapha rinodiae sp. nov. und Polycoccum galligenum sp. nov. Česká Mykologie 23(2): 104-109 (published: 1969) abstract Two new species of lichen-inhabiting fungi from Czechoslovakia are described. Opegrapha rinodinae sp. nov. grows parasymbiontically in the thallus of Rinodina nimbosa; first discovered in the Belauer Tatra, later found also in Norway. Polycoccum galligenum sp. nov. forms wart-like galls on the thallus of Physcia dubia in which its fruiting bodies are embedded; known so far only from SW Moravia.
