Occurrence of Lycogala epidendrum (Myxomycetes) in a mangrove environment in Brazil

The first record of Lycogala epidendrum (L.) Fries in Brazil was presented at the beginning of the 20th century based on material collected in the state of Santa Catarina (south region of the country). This species has been recorded in six of the nine states in the northeastern region, where it occurs in fragments of the Atlantic Rainforest, exhibiting lignicolous behavior, as well as in environments altered by humans. In a survey of the myxobiota of Maranhão state, northeast Brazil, aethalia were collected in the Araçagy mangrove, Raposa municipality (02o21’ to 02o32’ S and 44o00’ to 44o12’ W). This is the first time that L. epidendrum is reported for this type of environment. This was also the first record of a representative of Liceales (Myxogastromycetidae, Myxomycetes) in the myxobiota found in the state of Maranhão.No Brasil, o primeiro registro de Lycogala epidendrum (L.) Fries foi efetuado no início do século XX, baseado em material coletado no estado de Santa Catarina (Região Sul do país). Esta espécie foi registrada em seis dos nove estados da Região Nordeste, onde ocorre em fragmentos de Floresta Atlântica, comportando-se como lignícola, assim como em ambientes alterados pelo homem. No levantamento da mixobiota do estado do Maranhão, nordeste do Brasil, etálios foram coletados no manguezal de Araçagy, município de Raposa (02o21’ a 02o32’ S e 44o00’ a 44o12’ W). Esta é a primeira vez que L. epidendrum é registrada neste tipo de ambiente. Este é também o primeiro registro de um representante de Liceales (Myxogastromycetidae, Myxomycetes) no estado do Maranhão

Occurrence and distribution of Perichaena (Trichiaceae, Myxomycetes) in the Brazilian Northeastern Region

The known distribution of Perichaena calongei, P. chrysosperma, P. corticalis, P. depressa, P. microspora, P. pedata and P. vermicularis in the nine states that comprise Brazil's Northeast Region (1,548,672 km2) is presented herein, enhancing our understanding of the distribution of the genusPerichaena (Trichiaceae, Myxomycetes) in the Neotropics. This inventory encompasses a 100-year period (1914-2014), and analyzes material deposited in herbaria and collected by the authors. The collected material came from areas of thorny deciduous vegetation typical of the Caatinga biome and portions of savannah in the continent's interior, rainforests,restingas (tropical moist broadleaf forests found along Brazil's coastal spits) and mangroves of the Atlantic Forest biome along a coastal zone of approximately 3,000 km. Descriptions, illustrations, vegetational environments, microhabitats and distribution maps are given for each species. New records include Perichaena chrysosperma andP. depressa in the state of Maranhão, P. corticalis in the states of Bahia, Piauí, Rio Grande do Norte and Sergipe, P. calongei in the Northeast Region, and P. pedata in Brazil. This paper adds to the known types of macroclimates, elevation levels, vegetational environments and substrates for these species and provides a better understanding of their global distribution pattern
