Abstract

The first study of the Myxomycetes from the Mexican state of Sonora is presented. Seventeen taxa are new records for the Sonoran Mycobiota. Diachea subsessilis, Didymium rubeopus var. rubeopus and Trichia affinis are first records for Mexico. From a chorological point of view two taxa are interesting: Hemitrichia parviverrucospora status and comb. nov. and Metatrichia horrida. SEM photographs of the most important characteristics of these five species are provided.
