New records of genera and species of myxomycetes (Amoebozoa) from the Neotropics

During feld surveys of myxomycetes in Central America, 2 previously unrecorded genera and 4 species, viz. Craterium muscorum Ing, Dictydiaethalium dictyosporum Nann.-Bremek., Physarina echinocephala Höhn, and Stemonaria rufpes, were identifed. Some of these are new for the Neotropics. These noteworthy range extensions of these species to the Mesoamerican biodiversity hotspot adds to our knowledge of rarely recorded myxomycetes worldwide. Images of the more relevant taxonomic characters are provided, and for some species, this is the frst illustrations with macro and microphotographs and scanning electron microscopy images.Myxotropic Project/[CGL2014-52584P]//EspañaConsejo Superior de Investigaciones Científicas/[COOPB20155]/CSIC/EspañaUniversidad de Costa Rica/[731-B7-717]/UCR/Costa RicaUniversidad de Costa Rica/[731-B4-900]/UCR/Costa RicaUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ingeniería::Instituto Investigaciones en Ingeniería (INII)UCR::Sedes Regionales::Sede del Atlántico::Recinto de Paraíso::Finca Experimental Interdisciplinaria de Modelos Agroecológicos (FEIMA
