Erzberger, P.; Schröder, W.: The genus Schistidium (Grimmiaceae, Musci) in Hungary

However, for the study of Scbistidium distribution in Hungary, these areas may still hide unexpected treasures. Species like S. brunnescens, S. crassipilum, S. elegantulum and S. belveticum with a strong substrate preference for calcareous rocks naturally show their maximum number of sites in the carboniferous mountains (Aggtelek Karst, Bükk, Pilis, Buda, Gerecse, Vértes, Bakony, Mecsek, Villány Mts). On the other hand, among the more frequent species, S. apocarpum and S. lancifolium, both have most growth sites in the Börzsöny Mts (and less in the Zemplén, Visegrád, Mátra and Bükk Mts), thus demonstrating a preference for siliceous substrates. The distribution maps of the less frequent species give immediate evidence of their respective substrate preferences: S. robustum, S. brunnescens subsp. griseum, S. confusum and S. dupretii predominantly grow on calcareous rocks (Bükk, Pilis, Buda, Vértes, Bakony Mts), whereas S. pruinosum, S. papillosum, S. confertum and S. flaccidum are found exclusively on siliceous rocks (Zemplén, Bükk, Mátra, Börzsöny, Visegrád Mts).
