Morphological studies are made on specimens referred to Myriogenospora atramentosa and Balansia linearis. Stromata of both are epibiotic, linear, and have immersed perithecia. In addition, development of ascospores proceeds in a similar fashion. Linear filamentous ascospores disarticulate to form short segments that reinitiate bipolar growth at opposite ends to form fusoid‐shaped part‐spores. This method of part‐spore development is unknown to occur in other Clavicipitaceae. As a result of the common features of these species, it is proposed that B. linearis be classified in the genus Myriogenospora . Aspects of the biology and taxonomy of these species are discussed.
