Corticolous myxobiota of the Pernambuco Center of Endemism, Brazil

Abstract

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.

Licea pescadorensis, A New Myxomycetes Record for Turkey

“…Some members of this genus have been reported from fimicolous or corticolous habitat (Chung and Liu, 1996;Everhart and Keller, 2008;Barbosa et al, 2016). Licea tenera, originally described as corticolous on Acer, was emended by Martin and Alexopoulos (1969) to include coprophilous population.…”
