of subterranean ascomycetous fungi, are very closely related. By their parasitism they are markedly separated from other species which infect insects and spiders. However in their general morphology they are similar to the other species of the genus. Two species, C. ophioglossoides and C. capitata, have been recognized on Elaphomyces in Europe. In addition C. canadensis and C. nigriceps have been described from North America. Both however are usually treated as synonyms of C. capitata. C. intermedia, C. japonica and C. jezoensis have been described from Japan. The stromata of these species are elongated, either clavate or capitate. They are attached to the ascocarps of the subterranean hosts either directly
