“…Although Comatricha pulchella, Physarum auriscalpium, Stemonaria fuscoides and S. irregularis have only been reported from mangroves of Rio Formoso (Tab. 1), they occur as lignicolous or suculenticulous at other localities in CEPE and in Caatinga and Cerrado vegetation in northeastern Brazil, with the exception of S. fuscoides (Rufino & Cavalcanti 2007;Tenorio et al 2009;Ferreira & Cavalcanti 2011).…”

Situated within the Atlantic Forest domain, the Centro de Endemismo Pernambuco (Pernambuco Center of Endemism) -CEPE is regarded as a priority for biodiversity conservation worldwide. Covering an area of approximately 56,000 km 2 , it encompasses part of the states of Alagoas, Pernambuco, Paraíba and Rio Grande do Norte in northeastern Brazil. Here we present an identifi cation key to 73 species of Myxomycetes that compose the known corticolous myxobiota of the Dense Ombrofi lous Lowland Forest, Semideciduous Lowland Forest, Restinga Forest and Mangrove environments of CEPE. Specimens included here were found developed in natural conditions in the fi eld or obtained through moist chamber culture. Among the species found, Arcyria cinerea, Clastoderma debaryanum, Cribraria confusa, C. violacea and Echinostelium minutum were the most common; and Comatricha longipila, Licea pedicellata, Paradiachaeopsis longipes, Perichaena calongei and Stemonaria fuscoides were the most rare. Our data indicates that the species richness of corticolous myxomycetes in rainforests is lower than that of temperate forests. Th ese same data also suggest that taxonomic diversity (mean number of species per genus) is similar to, or higher than, that found in temperate regions of the world.

Context Cacti are endemic to North and South America, but numerous species have been spread all over the world after Europeans visited the Americas. Their global spread has impacted various aspects of terrestrial ecosystems, including the distributions of succulenticolous myxomycetes. Aims In this study, we examine the association of myxomycetes (also known as plasmodial slime moulds or myxogastrids) with three introduced species of cacti in Australia. Methods Using the moist chamber culturing technique we prepared 33 cultures from dead portions of three species of cacti collected in New South Wales and Queensland. Key results Eighty-eight percent of moist chamber cultures yielded evidence of myxomycetes (either plasmodia or fruiting bodies). A total of 12 species representing six genera were recorded. Physarum compressum was the most abundant species (appearing in 20 of the 33 cultures), with species such as Perichaena depressa also relatively common. We also report the first records of Perichaena luteola in Australia. Conclusions This is the first study to investigate the assemblages of myxomycetes associated with members of the Cactaceae in Australia, and we highlight the occurrence of succulenticolous myxomycetes on the continent. Implications This study leads to a better understanding of the biogeography, distribution and ecology of succulenticolous myxomycetes. We also add a new species record for Australia.
