THE GENUS TYMPANIS

Abstract

This paper is a taxonomic study of the genus Tympanis with a discussion of its history, morphology, conidial relations, parasitism, and distribution. Thirty-six species and one variety are recognized, of which 23 species have been studied in cultures. Sixteen new species are described and one new name is proposed. The conidial states of Tympanis species belong in the form genus Pleurophomella v. Höhn. In a section on doubtful and excluded species an attempt is made to account for all the Tympanis names in the literature.
