Rhabdoweisia crispata (Dicks.) Lindb.

SPECIMEN EXAMINED. — Croatia. Papuk Nature Park, siliceous outcrop above the Šumečica stream near the mountain peak Vranov vrh, 45°32’58.3’’N, 17°38’38.2’’E, 498 m a.s.l., 13.X.2016, leg. and det. A. Alegro & V. Šegota s.n., conf. B. Papp, BP(BP193752), ZA(ZA45485).

It was found in an acidophilic beech forest, on the bottom of the permanently humid and shaded vertical siliceous outcrop above the stream bank. The species was growing on a tiny layer of loamy soil above the rock, forming loose patches. This locality is not situated in the Mediterranean part of Croatia. Capsules were present, but not abundant. The whole rock was rich in bryophytes, consisting of Blepharostoma trichophyllum (L.) Dumort., Calypogeia fissa (L.) Raddi, Cephalozia bicuspidata (L.) Dumort., Dicranum montanum Hedw. , Diplophyllum albicans (L.) Dumort., Grimmia hartmanii Schimp. , Heterocladium heteropterum (Brid.) Schimp. , Homalia trichomanoides (Hedw.) Brid. , Lophocolea heterophylla (Schrad.) Dumort. , Pellia epiphylla (L.) Corda, Plagiochila porelloides (Torr. ex Nees) Lindenb. , Plagiothecium curvifolium Schlieph. ex Limpr. , P. nemorale (Mitt.) A. Jaeger , Polytrichum formosum , Rhizomnium punctatum (Hedw.) T.J. Kop. and Scapania nemorea (L.) Grolle. Rhabdoweisia crispata is a discontinuously Oceanic Boreal-montane species ( Hill & Preston 1998; Smith 2004), present in North-western and Central Europe ( Frey et al. 2006). It is extremely rare in SE Europe ( Hodgetts 2015), recorded solely in Bulgaria ( Natcheva et al. 2006) and Romania ( Stefănuţ & Goia 2012). It is known also from neighbouring Italy ( Aleffi et al. 2008). The species is VU in Bulgaria ( Natcheva et al. 2006).
