Colonies effuse, brown, hairy, often inconspicuous. Mycelium partly superficial, partly immersed in the substratum, composed of pale brown to brown, septate, branched hyphae. Teleomorph: Unknown. Anamorph: Conidiophores macronematous, mononematous, solitary, simple, cylindrical, straight or slightly flexuous, smooth, septate, brown to dark brown. Conidiogenous cells integrated, terminal, lageniform, smooth, brown to dark brown. Conidial ontogeny holoblastic, one locus per conidiogenous cell, solitary conidia, delimitated by one septum, maturation by diffuse wall-building, secession schizolytic, no proliferation. Conidia acrogenous, solitary, dry, cylindrical, obclavate, rostrate, smooth, pale brown to brown, distoseptate, cell lumina reduced; apex extended into a filamentous, branched and septate appendages (Adapted from Wu and Zhuang 2005).
Ecology/Substrate/Host: Saprobes on decaying plant material.
Known distribution: China and India.
Description and illustration: Subramanian (1954).
Notes: Lomaantha, typified by L. pooga, is similar to Ellisembia Subram., but differs by the conidia with branched appendages at the apex (Subramanian, 1954, 1992). Some species of Ellisembia also produce appendaged conidia, but their appendages are unbranched (Ellis 1958, 1971, 1976; Matsushima 1971, 1975, 1983, 1989, 1993). The ITS and LSU sequences of the type species were obtained from the two Chinese collections (Wu1518a and Wu1357a), and the affinity of this genus to Chaetosphaeriaceae was confirmed. Both ITS and LSU sequences are with high identity with those from Ellisembia. We propose to maintain this genus as a separate one until the phylogenic relationship of type species of Ellisembia, Ellisembia coronata, is clarified. It might be adapted as a potential generic name for those Ellisembia species in Chaetosphaeriaceae.
Type species: Lomaantha pooga Subram.
