Didymium clavodecus (Myxomycetes) una especie Americana nueva para Europa
Abstract
Didymium clavodecus, a species described from USA, has been found in Spain. Didymium clavodecus is described and illustrated by L.M. and S.E.M. photographs.
Three collections of a rare Didymium species were found on decaying desert vegetation (Agave shawii Engelm. and Yucca sp.) in Baja California, Mexico. A detailed description, including SEM-micrographs, is given for this new species. Didymium mexicanum is distinguished by its characteristic spore ornamentation.
Ten taxa of Myxomycetes from Baja California, México, were studied using light and scanning electron microscopy. Comatricha anomala, Didymium clavodecum, Physarum brunneolum and P. straminipes represent new records for Mexico. Badhamia gracilis, B. nitens, Fuligo cinerea, F. intermedia and Perichaena luteola are new records for Baja California. The variety Badhamia nitens van aurantiaca is proposed.
