Plants small to medium-sized, terrestrial when young and then climbing on tree trunks or rock surfaces. Rhizome long creeping up to 1 m or up to 2-3 m, densely scaly; scales reddish brown, transparent, lanceolate, clathrate, margin sparsely denticulate, long acuminate. Fronds distant; stipe present or fronds subsessile; laminae variable in shape, lanceolate, linear-lanceolate, or polymorphic, fronds on lower part of rhizome like Hedera leaves, toward apex becoming linear-lanceolate, base from cordate to truncate and narrowly cuneate; lamina herbaceous to papery, glabrous except for small clathrate scales on adaxial side of midribs; midribs prominent, veinlets not clear, anastomosing, free included veinlets simple or forked. Sori small, orbicular, densely scattered; paraphyses uniseriate, 3-6-celled or in part peltate (especially in young sori).
About three species: distributed mainly in C and SW China, also to N Vietnam and E Himalayan regions; three species in China.
In other treatments, all species of Lepidomicrosorium have been included within Microsorum superficiale (e.g., Nooteboom, Blumea 42: 366. 1997).
