An interesting aquatic ascomycete was found that appeared to possess characteristics of some members of the Sordariales. Subsequent sequencing of the 28S large subunit rDNA and β-tubulin genes confirmed the morphological data by placing it in the Sordariales but failed to provide support for placing this species in any recognized genus. Therefore, a new genus, Cuspidatispora, is erected to accommodate Cuspidatispora xiphiago, which is described as a new species based on a combination of morphological and molecular data. Cuspidatispora xiphiago is unique in possessing a central, melanized ascomal wall layer and apiosporous ascospores with a pronounced apical wall extension.
