Neoorthocaulis L.Söderstr., De Roo & Hedd. , gen. nov.

Folia plerumque trilobatae, usque ad 0.3-0.4 laminis partitis. A Orthocauli affinis sed amphigatriis grandis et bilobatis vel nullis et sequenciis ITS, rsp4, trnG et rpoC1 differt.

Type:— Neoorthocaulis attenuatus (Mart.) L.Söderstr., De Roo & Hedd. , comb. nov.

Synonym:— Lophozia sect. Attenuatae Schuster (1969: 306) . Type: Lophozia attenuata ( Martius 1817: 177) Dumortier (1835:17) , nom. illeg.

Shoots 1–5 cm long. Leaves (2-)3(–4) lobed, lobes mostly acute, lacking cilia on the postical margin ( N. attenuata , N. binsteadii ) or with 1–3 cilia ( N. floerkei , N. hyperboreus ). Trigones small to bulging. Underleaves lacking or large and bifid (in Orthocaulis small and unlobed). Gemmae absent or green to red. Dioicious. Perianth longly exserted, cylindrical, plicate.

Etymology:—This genus consists of most species that Buch (1933) included in his genus Orthocaulis except the species lectotypifying that genus.

Note:— Lophozia sect. Attenuatae R.M.Schust. is described as belonging to subgenus Orthocaulis . The genus/subgenus Orthocaulis is typified by Kitagawa (1963) with O. atlanticus but this apparently escaped Schuster who typified it with O. kunzeana . Schuster then included Lophozia (Orthocaulis) atlantica (H.Buch) Schiffner (1901: 46) in his new section Attenuatae making it an illegitimate name according to Art. 22.1 in ICBN ( McNeill et al. 2006).
