Abstract
Eogonocormus gen. nov., a new Early Cretaceous fern of
Hymenophyllaceae from north-eastern China, is described based upon the type
species Eogonocormus cretaceum sp. nov. The frond is
small, thalloid, dichotomous and with a creeping rhizome. The sori are
rounded, borne marginally on the fan-like ends of pinnule lobes, with
8–12 sori in each lobe. The spores are rounded or subrounded, trilete,
with baculate, granulate, spinate and reticulate sculptures.
Hymenophyllites linearifolius Deng is re-examined and
transferred to the new genus as E. linearifolium based
upon the characteristics of its sori.
