摘要：

Ceratosphaerella is described as a new genus for C. castillensis and C. rhizomorpha. The genus is related to Ophioceras but distinguished by ascomata with a basal stroma and shorter, fusiform ascospores. Muraeriata is described for M. collapsa and M. africana, two species that are distinguished by having a vacuolate middle ascomal wall layer. The ascospores resemble those of Ceratosphaerella and ascospores in both genera are morphologically similar to those of Ceratosphaeria lampadophora. Both new genera are placed in the Magnaporthaceae based oil LSU and SSU data. A species previously identified as Ophioceras tenuisporum was re-examined, found to fit the description of Pseudohalonectria phialidica and is transferred to Ceratosphaeria based on LSU data.. Lentomitella tropica and L. pallibrunnea are described for two species that have long-necked ascomata with pale brown, ellipsoid ascospores and large ascal rings. Sequence data from the LSU places them in a clade with hyaline-spored Lentomitella crinigera. and L. cirrhosa.
