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

The spinulose, flattened hair-point with visible lumina is quite unique to this species, it is not likely to be confused with any other Scbistidium species in Hungary. The rather short urn with strongly perforated peristome, and the preference of siliceous substrata are further characteristics. Habitat: In Hungary, S. confertum grows exclusively on dry, andesitic rock. In Scandinavia, it grows on dry, ± exposed siliceous or base-rich rocks (BLOM 1996, 1998). It prefers acid rocks in Catalonia (CASAS et al. 2001 ). Vertical distribution: 600-750 m a.s.l. Selected specimens examined: Mátra Mts: 8186/1 Com. Heves. In rupibus andesiticis siccis montis Disznókő prope pag. Parádfürdő, 750 m, 24.04.1952, leg. L. Vajda, BP 5608 and 111013 (sub Grimmia plagiopodia); Börzsöny Mts: 8079/1 Comit. Nógrád. In rupibus andesiticis siccis montis Hollókő, prope pag. Perőcsény, montes Börzsöny, leg. L. Vajda, 30.05.1962, BP 67976 (sub Grimmia apocarpa var. conferta); Comit. Nógrád. In rupibus andesiticis siccis cacuminis montis Hollókő prope pag. Kemence, montes Börzsöny, 21.04.1956, leg. L. Vajda, EGR. Plants medium-sized, forming rather loose tufts of variable colour (olivaceous, brownish or blackish). Central strand wide and distinct. Hair-point 0-0.65 mm, narrow throughout or sometimes ± abruptly widened at insertion, not coarse but stiff and ± straight, from not to longly decurrent, irregularly spinulose-denticulate with short, blunt spinulae.
