Type: K(M) 176510.
Epiphytes on the leaf lower surface. Superficial hyphae spreading over the host surface. Appressoria intercalary, composed of 3 cells, with the central cell swelling. Sexual state: Thyriothecia 260–285×150–163μm diam (x = 265×158μm, n=5) solitary and gregarious, superficial, easily removed from the host surface, black, opening by a linear fissure, with basal peridium poorly developed. Upper wall comprising linear, dark cells, which are branched at the margin. Hamathecium lacking pseudoparaphyses. Asci 50–55×46–50μm (x = 53× 48μm, n=10), bitunicate, fissitunicate dehiscence not observed, globose to subglobose, apedicellate, apical region of asci usually with a thick opaque region, ocular chamber not observed, not staining blue in IKI. Ascospores 29–34×14–17μm (x = 31×15μm, n=10), overlapping, oblong to obovoid, hyaline when immature, brown when mature, 1-septate, echinate, constricted at the septum. Asexual state: Unknown
Material examined: BRAZIL, Amazonas, on leaves of Elondia verrucosa, collected by E. Ule (K(M) 176510, isotype).
Notes: Cirsosia contains 15 species which are similar to Lembosia species. These need re-examining to confirm the distinctiveness and placement.
