Chenia leptophylla Zander 1993

Chenia leptophylla is one of a mundivagant group that is apparently distributed in association with human activities (P. M. Eckel 1986). The small brood bodies on rhizoids in the soil seem to be the agency for asexual reproduction. The very thin-walled distal laminal cells may appear bright yellow-green in KOH, but examination under the compound microscope reveals brick red walls. The elongate, thick-walled, reflexed cell forming the leaf apiculus is unique and immediately diagnostic.

Stems seldom branching; rounded in transverse section; rhizoids usually few. Leaves ligulate to elliptic, apex acute or rounded acute and apiculate with an elongate, brownish, thick-walled cell, costa percurrent or subpercurrent; proximal laminal cells ca. 20-25 µm wide, 2-4:1. Brood bodies sometimes present, borne on rhizoids in soil, clavate, ca. 100-130 µm. Sporophytes not known from North America.

Plants slender, 1.5–2.0 cm high, yellowish green to brownish. Stems erect, simple. Leaves loosely arranged, narrowly ovate-lanceolate, soft; margins more or less plane, entire below, irregularly denticulate above, broadly acute to apiculate at the apex; costa slender, subpercurrent; upper leaf cells quadrate to hexagonal, thin-walled, smooth; basal cells rectangular, thin-walled. Capsules ovoid; opercula short-conic, persistent with columella; peristome teeth absent.

Distribution: China, Japan, India, Africa, Europe, and North America.

Habitat: on rocks near streams.
