Scapania marsupelloides sp. nov. (Scapaniaceae, Marchantiophyta), a remarkable new species near the base of Scapania phylogeny

摘要

Scapania marsupelloides is described as new to science based on collection from Yunnan, China. The species looks different from the other known Scapania species and similar to Marsupella sphacelata. Molecular phylogenic analyses of ITS1-2 and trnL-trnF sequences suggested the close affinity of Scapania marsupelloides to S. contorta of the subgenus Ascapania. Description, line drawings, color and SEM images, and keys for differentiation of S. marsupelloides from S. cuspiduligera, S. contorta, S. pseudocontorta, S. hians and Marsupella sphacelata are provided.
