Rhizome 1-5 mm in diam., dorsiventrally flattened, not white waxy, bearing scales and hairs. Scales pseudopeltate, appressed or distinctly spreading or slightly spreading, ovate or narrowly ovate or triangular, 1-6.5 × 0.5-2.5 mm, margin entire or denticulate or dentate (sometimes with small triangular lobes), apex acute or rounded, clathrate, subclathrate, or clathrate except for hyaline marginal region, cells longitudinally rectangular, central region bearing multiseptate hairs at least when young or central region glabrous. Fronds not or slightly dimorphic. Lamina simple, narrowly elliptic to narrowly ovate to narrowly deltoid to linear, 3-40(-60) × 0.5-6 cm, herbaceous to subleathery, base truncate-decrescent to narrowly decrescent, margin entire to sinuate to undulate, apex acute to acuminate. Sori separate, sometimes forming 2-8 irregular rows between veins or in 2 (irregular) rows between each pair of lateral veins (occasionally in part confluent), orbicular (or in part slightly elongate), 1-2.5 mm in diam., superficial or slightly sunken.

Epiphytic or epilithic; 200-2000 m. Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, Sichuan, Taiwan, Xizang, Yunnan, Zhejiang [India, Indonesia (Java, Sumatra), Japan, Laos, Malaysia (Peninsular), Myanmar, Nepal, Thailand, Vietnam].

Nooteboom (Blumea 42: 366. 1997) included Lepidomicrosorium buergerianum and L. subhemionitideum within L. superficiale, but those taxa are here treated as distinct on the basis of the presence of paraphyses.
