Saprobic on the host plant. Sexual morph: Ascomata brown, superficial on the upper leaf surface, scattered or gregarious, immersed to semi-immersed, globose to subglobose, thick-walled, unilocular, glabrous, ostiolate. Ostiole conspicuous, center. Peridium wall, composed of thick-walled, brown to hyaline cells of textura oblita. Paraphyses 80–150 × 1.5–2.5 µm, hyaline, cylindrical, smooth-walled. Asci 75–100 × 10–15 µm wide (x= 88 × 13.5, n=20), hyaline, unitunicate, 8-spores, fusiform, slightly curved or straight, broad in the middle part, narrow at the both of ends, obtuse above, short-pedicellate, smooth, thick-walled. Ascospores 30–40 × 3–5 µm (x= 35.5 × 4, n=10), hyaline to brown, 3–4 seriates or multiseriate, fusiform, rounded at both ends, curved, up to 3 septate or several septate, not constricted at the septa, tapering gradually at both ends, thick-walled, smooth, hyaline. Asexual morph: Undetermined.
Type species: Lanatosphaera porinicola Matzer
Notes: Lanatosphaera was introduced by Matzer (1996) with L. porinicola as type species. Two species are accommodated in Lanatosphaera. The asexual morph is unknown. Cultures and sequence data is lacking for this genus.
