Drymoglossum carnosum Wallich ex J. Smith in Hooker, Gen. Fil. t. 78 A. 1841; Lemmaphyllum chui Saiki.

Plants to 15 cm tall. Rhizome ca. 1 mm in diam., densely scaly; scales ovate with caudate apex, margin entire. Fronds dimorphic. Sterile fronds: stipe 0.5-2(-5) cm, scaly at base; lamina broadly elliptic-lanceolate, ca. 10 × 2.5-3.8 cm, base cuneate and decurrent, apex bluntly acuminate. Fertile fronds: stipe 3-6(-8) cm; lamina narrowly oblong, up to 10(-15) × 0.4-0.5 cm. Sporangia in linear coenosori, eventually covering entire surface except costa and margin.

On tree trunks or rocks in forests; 1500-2900 m. Guizhou, Sichuan, Yunnan [India, Nepal, Thailand, Vietnam].

Lemmaphyllum carnosum is superficially very similar to Pyrrosia piloselloides (Linnaeus) M. G. Price. The two are separated by the stellate hairs of the Pyrrosia, which are sometimes very sparse.
