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

Costa and margins usually smooth, but sometimes with few papillae immediately below apex (Blom, pers. comm. in CASPARI 2004). Lamina smooth, irregularly bistratose or more rarely unistratose with bistratose patches in upper part. Lamina cells rounded, esinuose, (6-)7-8(-9) urn wide in upper part of leaf, 7-10 urn wide and slightly to strongly sinuose in central and lower parts of leaf. K+ red. Sporophytes common, deeply immersed, but partly exposed in lateral view. Urn yellowish to orange-brown, length / width ratio (1.4-)1.6-1.9-2.3(-2.5) (BLOM 1996), in Hungarian material (1.4-)1.6 ±0.14(-1.9), n = 7. Exothecial cells variable in size and shape, in central and lower part predominantly elongate, forming an irregular pattern (Fig. 21G, H). Stomata absent. Peristome teeth 300-430(-460) urn, orange to reddish, ending in a conical or flattened horizontal bar, often split in prongs at top, ± semi-perforated in lower part, strongly perforated to cribrose in upper part (Fig. 21I-L). Habitat: On often dry, more rarely humid calcareous rocks (limestone, dolomite) in usually open vegetation, often exposed to the sun. This habitat preference of Hungarian plants is the same as that reported in BLOM (1996). Associated bryophytes: Bryum argenteum, Didymodon acutus, D. luridus, D. rigidulus, Grimmia tergestina, Scbistidium brunnescens subsp. brunnescens, S. crassipilum, S. elegantulum. Vertical distribution: 200-600 m a.s.l. Selected specimens examined: Aggtelek Karst: 7589/1 Comit. Borsod-AbaújZemplén.
