Primeiro registro para o Brasil de Maravalia bolivarensis Y. Ono (Pucciniales) parasitando Manilkara sp. (Sapotaceae)

Abstract

-(First record for Brazil of Maravalia bolivarensis Y. Ono (Pucciniales) parasitizing Manilkara sp.(Sapotaceae)). This study presents a taxonomic treatment of the phytopathogenic fungus Maravalia bolivarensis (Pucciniales) causing rust in plants of Manilkara sp. (Sapotaceae), in the Amapá National Forest, Amapá State, Brazil. Previously known only from Venezuela, this is the fi rst record of M. bolivarensis for Brazil, and its original distribution is extended to the Amazon Biome. Morphological descriptions, illustrations of the microstructures, examined material, geographic distribution and taxonomic comments are provided for this species. Additionally, Maravalia sapotae (Mains) Y. Ono was also recorded in the Amapá National Forest and is being referred here for the fi rst time to the state of Amapá. Finally, an identifi cation key including species of the teleomorph genera Achrotelium, Catenulopsora and Maravalia that occur on plants of Sapotaceae in Brazil is presented.

Two new species of rust fungi (Pucciniales) from the Brazilian Amazon: Aecidium margaritariae on Margaritaria and Uromyces amapaensis on Jatropha

“…It is used as an aid in the identification of the species, complementing morphological and molecular studies of the different stages of their complex life cycles (Cummins and Hiratsuka 2003;Passador 2009, 2014;Aime et al 2006Aime et al , 2018. About 3,000 species of fungi are reported for the Brazilian Amazon, including those of the order Pucciniales (Basidiomycota), represented by 199 known species causing rust on plants, of which 55 occur in the northern Brazilian state of Amapá (França et al 2010;Carmo et al 2016;Carvalho et al 2018;Furtado et al 2018;Flora do Brasil 2020).
