“…In addition, partial SSU sequence of D. dalatense is only 79% similar to the published sequences of D. velutinum. D. albocolumella described from Brazil (Bezerra and Cavalcanti, 2010) is similar to the new species, because it has a triple peridium, a large spherical columella and warted spores. However, it has flattened hemispherical to discoid sporangia, white columella and larger spores (10.5-13.0).…”

A new species of Diderma, described herein as D. dalatense, was found in ground leaf litter in mixed montane tropical forests (Bidoup Nui Ba National Park) of southern Vietnam. This species was discovered during intensive studies on the distribution and ecology of fungi and myxomycetes in tropical forests of Vietnam in the context of a long-term project Ecolan 1.2. The morphology of representative specimens was examined by light and scanning electron microscopy, and micrographs of relevant details are provided. D. dalatense has unique combination of morphological characters of the sporocarps among species of Diderma including very small (0.2-0.4 mm in diam.) dark-yellow, globose to subglobose sessile sporocarps, large conical or subglobose yellow columella, smooth peridium with three layers resembling that of Leocarpus and irregularly warted spores. In addition to the morphological description, partial sequences of three genetic markers of this new species (SSU, EF1A, COI) were obtained and submitted to GenBank. The stability of the taxonomic characters of the species was confirmed by several collections obtained in different localities of the National Park.

“…The new species differs in a number of important cha rac ters from other species that have sessile globose and sub glo bose sporangia with the yellowish, reddish brown or och raceous peridium and more or less developed co lu mella: Table 2). The for mer species described from Brazil (Bezerra & Cavalcanti 2010) is similar to the new species, because it has a triple pe ri dium, a large spherical columella and warted spores 10.5- Figs. 1, 2 , 7, 8, 10, 12, 15) and paratype LE 318753 9,11,13,14,16).…”

A new species, Diderma velutinum, is described and illustrated by LM and SEM mic ro graphs. Two specimens of this species were found in moist chamber cultures on the pieces of the bark of living tree of Phellodendron amurense, which was col lec ted in July 2016 and July 2017 in the Kedrovaya Pad State Nature Biosphere Re serve (the Russian Far East). The main distinguishing features of this species are triple peridium, large spherical columella and ochraceous colour of sporangia clus tered in dense groups. The partial 18S rRNA gene sequences of D. velutinum dif fer con siderably from all sequences of Diderma species available to the moment.

-(Atlantic Forest myxomycetes biota: new records of Physarales for the state of Paraíba, Northeast Brazil). The order Physarales encompasses the families Elaeomyxaceae, Didymiaceae, and Physaraceae, involving 16 genera and approximately 371 species, several of them well represented in the Neotropics. A study on the presence of this order in the Atlantic Forest ' (Cavalcanti 2002, 2005, MaimoniRodella 2002, Putzke 1996) o que corresponde a cerca de 20% do total de espécies mundialmente conhecido (Lado 2001(Lado , 2005(Lado -2010.Dentre as Myxogastromycetidae, as Physarales destacam-se na mixobiota brasileira pelo número e distribuição dos gêneros e espécies, que correspondem a 44% do total de representantes da subclasse conhecidos para o país. As espécies desta ordem ocupam os mais diferentes ambientes e microhabitats, com registros nas matas úmidas costeiras, nas caatingas, nos diferentes tipos de cerrado e até mesmo em manguezais (Cavalcanti , 2005. Em canaviais, material armazenado em indústrias, parques e jardins públicos ou residenciais, têm sido reportadas espécies de Badhamia, Craterium, Diachea, Diderma, Didymium, Fuligo e Physarum, particularmente na Região Nordeste, onde os estudos têm se concentrado nas últimas décadas .
