Orthotrichum diaphanum Schrad. ex Brid. Orthotrichum gymnostomum Bruch ex Brid. - known from a single locality, specimens: BP 25476, BP 156188 Comit. Pest. In truncos populi in populetis ad Móricgáti tanyák, 14.06.1953, leg. L. Vajda. Orthotrichum lyellii Hook, et Taylor Orthotrichum obtusifolium Brid. Orthotrichum pallens Bruch ex Brid. Orthotrichum patens Bruch ex Brid. - in BOROS (1968) under O. stramineum var. patens (Brid.) Venturi. Orthotrichum pumilum Sw. {Orthotrichum fallax Bruch ex Brid.; Orthotrichum schimperi Hammar). - contrary to BOROS (1968), ORBÁN and VAJDA (1983) modern taxonomists no longer distinguish between varieties of this species (LUDWIG et al. 1996, VITT 1973, LEWINSKY 1993). Orthotrichum rogeri Brid. Orthotrichum rupestre Schleich, ex Schwägr. (Orthotrichum sturmii Hoppe et Hornsch.). BOROS (1968), ORBÁN and VAJDA (1983) include var. sturmii (Hoppe et Hornsch.) Jur., but this taxon is no longer distinguished (LUDWIG et al. 1996, VITT 1973, LEWINSKY 1993). Orthotrichum scanicum Grönvall (Orthotrichum leucomitrium Bruch et Schimp.) Orthotrichum speciosum Nees Orthotrichum sprucei Mont. - Until its discovery by ERZBERGER and PAPP (2000) in Kiskunság, this moss was only known from oceanic Western Europe, but in the meantime it has been reported from Turkey (ERDAG and KÜRSCHNER 2000) and even Kasakhstan (GOFFINET 2002). Orthotrichum stellatum Brid. (Orthotrichum hraunii Bruch et Schimp.) Orthotrichum stramineum Hornsch. ex Brid. Orthotrichum striatum Hedw. (Orthotrichum leiocarpum Bruch et Schimp., nom. illeg., nom. superfl.). - BOROS (1968) distinguishes subsp. shawii Wilson, a taxon that is considered by MAZIMPAKA et al. (2000) as a good species. Revision of the specimens is necessary. Orthotrichum tenellum Bruch ex Brid. Orthotrichum urnigerum Myrin Oxystegus tenuirostris (Hook, et Taylor) A. J. E. Sm. (Oxystegus cylindricus (Brid.) Hilp.; Tortella cylindrica (Brid.) Loeske; Trichostomum cylindricum (Brid.) Müll. Hal., nom. illeg., horn, post.; Trichostomum tenuirostre (Hook, et Taylor) Lindb.). - inch var. gemmiparus (Schimp.) R. H. Zander; GALAMBOS (1986). Palustriella commutata (Hedw.) Ochyra (Cratoneuron commutation (Hedw.) G. Roth). Infraspecific taxonomy is controversial. BOROS (1968), ORBÁN and VAJDA (1983) mention 3 additional varieties (var. falcatum, var. ptychodioides and var. sulcatum), which Boros considers to be mere habitat modifications. However, var. commutata and vox. falcata (Brid.) Ochyra are treated as separate species by HEDENÄS (2003), the latter he calls Palustriella falcata (Brid.) Hedenäs. On the other hand, KOPERSKI et al. (2000) recognise 4 varieties: var. commutata, var. falcata (Brid.) Ochyra, war. fluctuons (Schimp.) Ochyra, (not reported from Hungary), and var. sulcata (Lindb.) Ochyra. The var. ptychodioides (G. Roth) Mönk. (sub Cratoneuron) mentioned in BOROS (1968), ORBÁN and VAJDA (1983) is included in P. commutata var. commutata by KOPERSKI et al. (2000). Whereas var. falcata and var. sulcata are kept separate by KOPERSKI et al. (2000), HEDENÄS (2003) places var. sulcata into synonymy with Palustriella falcata. Paraleucobryum longifolium (Hedw.) Loeske (Dicranum longifolium Ehrh. ex Hedw.). BOROS (1968) mentions a record by Latzel of var. hamatum Jur. (= f. hamatum (Jur.) Demaret), but not many authors recognise this form. Phascum curvicolle Hedw. (Microbryum curvicolle (Hedw.) R. H. Zander)
