Appressoria in Mycoleptodiscus species

Alcorn, J.L.

Appressoria formed by germinating conidia of Mycoleptodiscus species in vitro were examined as a possible source of taxonomic information. There were large differences in morphology between appressoria formed by the 12 taxa examined, and it is suggested that characteristics of the appressorium, such as size, shape, curvature, septation and germ pore size, provide additional differentiating criteria which are of use in the taxonomy of the genus. Three new species of Mycoleptodiscus are described, M. coloratus, M. geniculatus, and M. variabilis.
