(e.g. S. apocarpum, Fig. 3E) to squarrose-recurved (e.g. S. confusum, Fig. 11G). Apart from colour and papillosity, the size and shape of peristome teeth is important, as is the amount of perforation by pits and holes in cribrose peristome teeth. Fig. 1. Capsule walls without (B) and with striolae (C-G). A = transverse section of capsule wall (exothecium stippled); B = exothecial cells in Scbistidium apocarpum; C-E = exothecial cells in S. crassipilum at top of urn / in mid urn / at base of urn; F, G = exothecial cells in S. lancifolium in upper/lower part of urn. Scale bar: 200 urn. [Del. Schröder] RESULTS AND DISCUSSION According to the revision of all available herbarium material presented here, in Hungary the genus Scbistidium comprises fifteen taxa, which can be grouped in the following informal infrageneric categories (BLOM 1998): Rivulare group: S. platyphyllum (Mitt.)
