Abstrakt
Gymnomitriaceae Klinggräff (1858: 16) was thoroughly treated by Váňa et al. (2010). Since the publication, a series of papers have shown that the circumscription of the family and genera within the family must be revised.
Herzogobryum Grolle (1963: 160) and Nothogymnomitrion Schuster (1996: 43) was removed from the family by Váňa et al. (2013). Already de Roo et al. (2007) showed that Apomarsupella revoluta (Nees 1836: 419) Schuster (1996: 82) was nested in Gymnomitrion Corda (1829: 651) and Cailliau et al. (2013) showed that Apomarsupella rubida (Mitten 1861: 90) Schuster (1996: 85) also belongs there.
Thus the genus Apomarsupella Schuster (1996: 79) should be synonymized and the necessary combinations made. The necessary combinations are made elsewhere.
Two invalidly published names in Marsupella Dumortier (1822: 114) were used in Váňa et al. (2010). The first of these, Marsupella emarginata (Ehrhart 1784: 141) Dumortier (1835: 24) var. tubulosa, was assumed to have been established as an autonym under subsp. tubulosa (Stephani 1897: 99) Kitagawa (1960: 76) via the publication of var. patens (Stephani 1901: 162) Kitagawa (1960: 77) or of var. apertifolia (Stephani 1901: 162) Kitagawa (1963:89).
However, autonyms are only established directly under genera and species (cf. ICN Art. 22.1 & 26.1; McNeill et al. 2012) and thus var. tubulosa is invalid, which Váňa et al. (2010) overlooked.
The second name, Marsupella sparsifolia (Lindberg 1868: 280) Dumortier (1874: 128) subsp. childii Schuster (1996: 61), was invalidly published by Schuster (1996) as he did not indicate the herbarium in which the type specimen was lodged (as required under ICN Art. 40.7; McNeill et al. 2012). Váňa et al. (2010) explicitly did not validate the subspecies as they had not located the type material.
However, with the incorporation of Schuster's herbarium in F, the type material has now been found. Those two names are thus validated here.
