Ceratosphaerellais described as a new genus for C. castillensisand C. rhizomorpha. The genus is related to Ophiocerasbut distinguished by ascomata with a basal stroma and shorter, fusiform ascospores. Muraeriatais described for M. collapsaand M. africana, two species that are distinguished by having a vacuolate middle ascomal wall layer. The ascospores resemble those of Ceratosphaerellaand ascospores in both genera are morphologically similar to those of Ceratosphaeria lampadophora. Both new genera are placed in the Magnaporthaceae based on LSU and SSU data. A species previously identified as Ophioceras tenuisporumwas re-examined, found to fit the description of Pseudohalonectria phialidicaand is transferred to Ceratosphaeriabased on LSU data. Lentomitella tropicaand L. pallibrunneaare 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 crinigeraand L. cirrhosa.

An interesting wood-inhabiting pyrenomycete was discovered while collecting for the All Taxa Biodiversity Inventory currently being conducted in the Great Smoky Mountains National Park. This species is unique in possessing superficial ascomata with reddish tubercles and ascospores that develop an apical swollen brown cell and a long, basal hyaline cell. Because these ascospore characters fit the traditional morphological circumscription of Cercophora, this species is described as a new species within this genus.
