Project Results
The aims of the presented grant project was to compile the world-wide taxonomic study (monograph) of the genus Marsupella and related genera (Gymnomitriaceae, Hepaticae). On the generic level was the authorization of the genus Apomarsupella confirmed, the other published related genera (Lophonardia, Nanomarsupella, Paramomitrion, Poeltia) were transferred to different families. It was found that the basic criteria for the separating of taxa on the generic and subgeneric level in the family are the branching pattern, structure of the gynaeceum and structure of the seta in the cross section. The genus Marsupella is divided into 3 subgenera: subgenus Marsupella (perigynium of the Isotachis-type, perianth present) with 4 sections (section Marsupella with 8 species: M. alata, M. arctica, M. disticha, M. emarginata, M. paroica, M. pseudofunckii, M. sphacelata and M. yakushimensis, section Boeckiaewith 2 species: M. boeckii and M. microphylla, section Funckiae with 9 species: M. andreaeoides, M. bolanderi, M. funckii, M. minutissima, M. profunda, M. sparsifolia, M. spiniloba, M. sprucei and M. vulcanica and section Stolonicaulon with only one species M. stoloniformis), subgenus Homocraspis(perigynium lacking, perianth highly reduced) with 2 sections (section Homocraspis with 7 species: M. adusta, M. alpina, M. brevissima, M. commutata, M. miniata, M. minutula and M. nigra and section Neomarsupella with only one species M. subintegra) and, finally, subgenus Haylacme (perigynium of Nardia geoscyphus-type, perianth present) with only one species (M. condensata). The genus Apomarsupella (5 species: A. africana, A. revoluta, A. rubida and newly to this genus transferred taxa A. crystallocaulon and A. verrucosa) can be separated from the genus Marsupella by the Anomoclada-type branching and completely lacking perigynium and perianth, with the female bracts similar to those of the genus Marsupella. Many species (M. austrogeorgica, M. capensis, M. crenulata, M. cuspidata, M. exigua, M. fengchengensis, M. involuta, M. pusilla, M. rikuchiana, M. subhyalina, M. trollii, Sarcoscyphus (=Marsupella) kerguelensis etc.) were transferred to the other genera of the family or other families. The infraspecific taxonomy, geographical distribution etc. was specified for the all taxa. Nearly all taxa are known only from the holarctic region or from the highest mountains in the tropics; they are very rare in the subantarctic area. The key to the determination of species of two mentioned genera was prepared.
