Abstract:
The genus Lepidomicrosorum was separated from Microsorum Link by Ching
and Shing in 1983. It is characterized by minute scattered sori covered with peltate and sub-
sessile paraphyses when young. Tagawa detected that Polypodium subhastatum Baker, the
type of this new genus, has this kind of paraphyses and thus transferred this species to
Neocheiropteris Christ in 1952, a genus with divided lamina. During our study of the Mi-
crosoroideae, a revision of Lepidomicrosorum from China and neighboring regions is made on
the basis of field and herbarium observation and evidence from anatomy, spore morphology,
ecology, and distribution. Lepidomicrosorum is recognized as an independent genus and the
demarcation line of its species is reconfirmed. Species with peltate scale-like paraphyses in
Microsorum were transferred to Lepidomicrosorum. As a result, two species are recognized
in this species, i.e.L．buergerianum (Miq.) Ching et Shing and L. hymenodes (Kunze)
