Hygrohypnum smithii

The type species of Ochyraea, O. tatrensis was found in a clade with O. smithii with high support (Nona 99% MB 100%). Relationship of these species was found previously by Stech and Frahm (2001), and some morphological characters, for example pseudoparaphylUa, are very similar in these two species. Interestingly, the opinion of R. Duell (Ochyra, personal communication) on the holotype of Ochyraea tatrensis was that this is just au aberraut form of Hygrohypnum smithii. A clade with Drepanium recurvatum and Tomentypnum nitens was found also by Tsubota et al. (2004). These two species were the only representatives of this clade in that analysis of approximately 600 species of mosses. 

The taxa included are divided into two main clades that are well supported Hygrohypnum styriacum to Palustriella decipiens (Figure lO.lA), and Platydictya jungermannioides to Hygrohypnum smithii (the rest of the ingroup).
