| Abstract: | Based on the systematically taxonomic study of the genus Pohlia Hedw. in China, this paper revises a species of the genus with toruloid gemmae growing on the rhizoids, Pohlia lutescens. Morphological characters, geographical distribution and habitat of this species were discussed. The comparison among P. lutescens and its related species, P. cruda, P. hyaloperistoma and P. nutans, were also conducted. The result of identification of specimens shows that the distribution range in China of P. lutescens is expanded from five to ten provinces. Meanwhile, the distribution map of the species in China is provided. |
