A new genus, Claviradulomyces, morphologically typical of Odontotremataceae, is proposed to accommodate the new species Claviradulomyces dabeicola. The genus is characterised by its ornamented periphysoids, and long-cylindric, sigmoid, acuminate ascospores. Genetically, C. dabeicola falls within the Ostropales, but the Odontotremataceae have been very poorly sampled genetically and their phylogenetic relationship within the order is unclear. C. dabeicola has been collected consistently and exclusively on the rainforest tree Erythroxylum mannii in the Côte d'Ivoire and Ghana, where it is associated with bark abnormalities on branches and stems of living trees.
