Caracterização de fungos associados à vegetação de Mata Atlântica do Estado do Rio de Janeiro e alguns fungos endofíticos “dark septate” provenientes de Roraima, RR

Abstract

In this work were studied 19 fungal species associated to plants mainly from Atlantic forest of State of Rio de Janeiro. Among anamorphic hyphomycetes were found a probable new species of Cercospora on Tectaria (Tectariaceae); a probable new species of Pseudocercospora on Solanum asperum (Solanceae); a probable new species of Arthrinium on Pennisetum purpureum (Poaceae). Among the Coelomycetes, were found: a probable new species of Neopestalotiopsis on Inga laurina (Fabaceae); a probable new species of Colletotrichum on Solanum swartzisnum (Solanaceae). In the group of Ascomycetes, it was found a probable new species of Apiospora on Pennisetum purpureum (Poaceae); a probable new species of Asterinella on Eugenia florida (Myrtaceae); a probable new variety of Meliola, M. manaosellae var. nov. on Handroanthus ochraceous (Bignoniaceae); a probable new species of Meliola on Olyra sp. (Poaceae); Meliola sorindeiae on Astronium graveolens (Anacardiaceae); a probable new species of Myriagium on Ctenanthe sephora (Marantaceae); a probable new species of Perisporiopsis on Erythroxylon pulchrum (Erythroxylaceae); a probable new species of Scolecobonaria on Chlomolaena maximilliani (Asteraceae); a probable new genus on Justicia wasshauseniana (Acanthaceae). It was also characterized 5 species of endopophytic “dark-septate” fungi isolated from “wild rice” (Oryza glomaepatula) from the State of Roraima, depositated in the collection of Embrapa Agrobiologia, Seropédica – R.J. from these: a probable new species of dark-septate (AM 101) fungus from roots; a probable new species of Cladosporium (AM 102); a probable new genus (AM 103) in Lentitheciaceae (Ascomycota); a probable new genus (AM 104) in Lentitheciaceae (Ascomycota); a probable new genus (AM 105) in Lentitheciaceae (Ascomycota).
