Diversity and ecology of Myxomycetes in the Pampa Biome, Brazil
The first comprehensive study of Myxomycetes of the Brazilian portion of the Pampa biome is reported herein. Three field excursions took place in 2013 and 2015 at the APA Ibirapuitã for a biodiversity survey of 30 plots. Moist chambers were also prepared with samples collected in the study area. A total of 57 species were recorded, of which 28 are new records for the state of Rio Grande do Sul and 8 are new records for Brazil: Arcyria afroalpina, Craterium concinnum, Licea rufocuprea, L. tenera, Perichaena luteola, Physarum robustum, P. spectabile and Stemonitopsis gracilis. Notes on the ecology of myxomycetes and substrate preferences are provided. The results show that the two major phytophysiognomies of the region, grassland and riparian forest, have very distinct myxomycete assemblages due to their differing vegetation and microclimatic conditions.

More about this publication?
- Nova Hedwigia is an international journal publishing original, peer-reviewed papers on current issues of taxonomy, morphology, ultrastructure and ecology of all groups of cryptogamic plants, including cyanophytes/cyanobacteria and fungi. The half-tone plates in Nova Hedwigia are known for their high quality, which makes them especially suitable for the reproduction of photomicrographs and scanning and transmission electron micrographs.
