Erzberger, Peter: Funaria muhlenbergii and Funaria pulchella (Funariaceae, Bryophyta) in Hungary

Studia bot. hung. 33, pp. 47-63, 2002 FUNARIA MUHLENBERGII AND FUNARIA PULCHELLA (FUNARIACEAE, BRYOPHYTA) IN HUNGARY P. ERZBERGER Beiziger Str. 37, D-10823 Berlin, Germany The distribution of the two moss species Funaria muhlenbergii and F. pulchella in Hungary has been established by revision of the specimens in BP. Contrary to the picture suggested by the Hungarian literature to date, F. pulchella is about as frequent as F. muhlenbergii. The records of the species are presented in two maps. Some of the morphological features useful in identification of the species are discussed and in part illustrated. The number of stomata per sporophyte is a good discriminating character that significantly differs between the two species: F. muhlenbergii has (43-)72(-101) stomata per capsule, F. pulchella (19—)3

1 (—42). An analysis of the collection data reveals that the two species may differ slightly in the time of ripening of the sporophyte, since on average the capsules of F. muhlenbergii open about two weeks later than those of F. pulchella. Key words: bryophytes, distribution, Funaria, Hungary, morphological characters, taxonomy INTRODUCTION The species of the Funaria muhlenbergii group were poorly understood before the basic work of CRUNDWELL and NYHOLM (1974), in which three species are recognised: F. muhlenbergii Turner, F. pulchella Philib. and F. conica Spruce, the latter a more strictly Mediterranean species that does not occur in Hungary and will not be considered further. In earlier works (e.g. LIMPRICHT 1895, MÖNKEMEYER 1927) the names F. dentata Crome and F. mediterranea Lindb. were in use for the taxa now called F. muhlenbergii and F. pulchella, respectively (see also Discussion), although, taxonomically, these are synonyms of F. muhlenbergii, since their types belong to this species (CRUNDWELL and NYHOLM 1974). Boros and other Hungarian collectors used these older names in herbarium labels, but in his monography, BOROS (1968) follows the taxonomic concept of LOESKE (1929), who considered F. mediterranea not to be specifically distinct from F. dentata and attributed to it the rank of a variety only. However, BOROS (1968) uses the name F. muhlenbergii instead of F. dentata, and he considers F. mediterranea to be merely a habitat form ("Standortsform"), occurring with the type. Although in the revision of CRUNDWELL and NYHOLM (1974), three Hungarian specimens are mentioned - two of F. muhlenbergii (Vértessomló, Csákberény) and one of F. pulchella (railway between Alsógöd and Dunakeszi) -, their concept has up to now not been fully applied to the taxa occurring in Hungary.
