Diploschistella athalloides (Nyl.) Lücking, K. Knudsen & Fryday

A rarely reported but widely distributed (occurring also in Australia) terricolous taxon from a broadly delimited genus Gyalideopsis. It has been reported under three different species names (Gyalecta steinii, Gyalidea psammoica and Gyalideopsis athalloides) from the Czech Republic. Though all were related to the only historical finding described under the first-mentioned name from the surroundings of Havlíčkův Brod (Novák 1888). The lichen grows on acidic, clayey to sandy compact soil. In the Czech Republic, Diploschistella athalloides has been recorded on heathlands in a company of the moss Polytrichum piliferum, various Cladonia species, Dibaeis baeomyces, and some members of the genus Placynthiella (Lettau 1937, Vězda 1972).
