“…In terms of biogeography, most studies have been carried out in temperate regions of the Northern Hemisphere, including alpine and subalpine mountains (Ronikier & Ronikier, ; Novozhilov et al ., ), tundra (Novozhilov et al ., ; Stephenson et al ., ), winter‐cold deserts (Schnittler & Novozhilov, ; Schnittler, ; Novozhilov & Schnittler, ) and temperate grasslands (Rollins & Stephenson, ). Only recently have other parts of the world, such as tropical zones, warm deserts or the Patagonian steppe been studied systematically (Estrada‐Torres et al ., ; Wrigley de Basanta et al ., ; Lado et al ., , , ). At the level of morphologically recognizable taxa, many myxomycete species display cross‐continental distribution patterns (Stephenson et al ., ).…”

“…These range from country checklists (Brazil, Cavalcanti, 2010;Colombia, Rojas et al, 2012a;Costa Rica, Rojas et al, 2010;El Salvador, Rojas et al, 2013) to abundance-based diversity assessments of natural habitats (Lado et al, 2003;Rojas & Stephenson, 2012). About half of the c. 1000 known morphospecies of myxomycetes (Lado, 2005(Lado, -2016 have been recorded from the Neotropics . Our knowledge of myxomycete diversity of the Asian Palaeotropics is more limited, and c. 200 taxa are known.…”

Aim Lowland/highland and Neotropical/Asian Palaeotropical assemblages of myxomycetes were compared to test the null hypothesis that neither species diversity nor species composition differs between the two ecoregions. This can be expected if myxomycetes behave as ubiquists and are capable of unlimited long distance dispersal. Location Four pairs (lowland/highland) of comprehensive regional surveys encompassing c. 7500 specimens were compared; these represented Neotropical (Yasuni/Maquipucuna in Ecuador; Guanacaste/Monteverde in Costa Rica) and Asian Palaeotropical forests (Cat Tien/Bi Dup Nui Ba in Vietnam; Chiang Mai in Thailand/South Luzon in the Philippines). Methods Each survey was carried out in an area characterized by relatively homogenous vegetation consisting of natural or near‐natural forests, and incorporated both field collecting and the use of moist chamber cultures, and all observed fructifications were recorded. Analyses of diversity (i.e. richness) and community composition were carried out with EstimateS and R. Results Between 400 and 2500 records per survey were obtained. Species accumulation curves indicated moderate to nearly exhaustive completeness (70–94% of expected species richness recorded). Multivariate analyses suggest that geographical separation (Neotropic versus Palaeotropic) explained the observed differences in composition of myxomycete assemblages better than habitat differences (lowland versus highland forests). Main Conclusion Both geographically restricted morphospecies and differences in myxomycete assemblages provide evidence that myxomycetes are not ubiquists but tend to follow the moderate endemicity hypothesis of protist biogeography.

“…Most of these organisms barely exceed a millimeter in size and are found in all terrestrial ecosystems. They have been traditionally associated with humid temperate environments, due to the need for water to complete their life cycle, but their presence in arid environments is also frequent (Lado et al 2016(Lado et al , 2019.…”

We report 19 species of Myxomycetes for first time in Peru. Macbrideola spinispora L.M. Walker, G. Moreno & S.L. Stephenson, previously known only from the type collection from Costa Rica, is now reported for South America, enlarging its distribution considerably. The Myxomycetes were collected in Wayqecha Biological Station, a conservation area in the Cuzco region. The specimens were deposited in the South Peruvian Herbarium (HSP) and the Real Jardín Botánico de Madrid (MA-Fungi). The number of Myxomycetes currently recorded from Peru is increased to 174 species.

The results obtained from a second survey for Myxomycetes in the arid areas of Peru are reported. A total of 37 localities from the cactus belt (‘cardonal’), between 1500 and 3000 m a.s.l., were sampled over six years. This survey is based on 601 identifiable collections of myxomycetes, developed in the field under natural conditions or those that were recovered from moist chamber cultures. In total, 84 taxa representing 19 genera were recorded. One new species, Cribraria spinispora Lado & D.Wrigley sp. nov., is described, three species new to South America and 22 additional new species for Peru are reported as well. Endemic plants, expecially cacti, had a particular relevance as myxomycete substrates. The predominance of the order Physarales T.Macbr. in arid areas is reinforced. Comments are included on some collections, as well as SEM micrographs of several species. A statistical evaluation of the diversity of myxomycetes in the cardonal area and a comparison of this area with the dry coastal desert of Peru and other Neotropical xeric environments are also included. Results show that the arid areas are rich in myxomycetes, and that each area has a unique assemblage. The differences appear to be related to the host plants.
