subg. Scapania Pseudomacrodiplophyllum Vana, Hentschel, Joch. Muell. & Heinrichs subg. nov.

Diagnosis.

Scapania subg. Pseudomacrodiplophyllum includes species which differ from other Scapania elements by the presence of multicellular gemmae with intersecting walls, basal leaf cell walls with intermediate thickenings and pluriplicate perianths.

Type.

Scapania microdonta (Mitt.) Müll. Frib., Nova Acta Acad. Caes. Leop.-Carol. German. Nat. Cur. 83: 262. 1905.

Note.

Scapania microdonta [ Macrodiplophyllum microdontum (Mitt.) Perss.] forms the sister clade to the rest of Scapania ( Vilnet et al. 2010, Heinrichs et al. 2012); hence, a new subgenus is introduced here to accommodate this species ( Fig. 1 ).
