RESUMO
Five new species, two new varieties and three newly reported taxa belonging to the Meliolaceae were collected in fragments of Atlantic forest from Minas Gerais, Brazil, in association with native plants and are described and illustrated herein. The newly described species are Appendiculella eupatorii, Meliola cassiae-ferrugineae, M. mutisiae, M. peruiferae, M. vernaliae. The new varieties are M. garugae var. protii and M. paullinifolii var. rubiginosae. These taxa are reported in Brazil for the first time: Asteridiella cyclopoda, A. entebbeensis var. codiaei and Meliola pazschkeana var. macropoda. We studied other species belonging in Meliolaceae collected on hosts belonging to the Asteraceae, Burseraceae, Euphorbiaceae, Fabaceae (Caesalpinioideae and Papilionoideae) and Sapindaceae in Brazil.

The new combination Calidion bombacis is proposed for the rust species formerly known as Uredobombacis. This nomenclatural change is based on the examination of newly collected material of this fungus from a new host, Bombacopsisglabra from Brazil, and reexamination of the isotype. Until now this fungus was only known to occur in Asia (China, India and Sri Lanka). Therefore, this is also the first record of this fungus from the Neotropics.
A combinação nova Calidion bombacis é proposta para a ferrugem anteriormente conhecida como Uredo bombacis. Esta modificação nomenclatural é proposta baseada no exame de material deste fungo coletado em um novo hospedeiro, Bombacopsisglabra (Bombacaceae) no Brasil e reexame do isotipo. Até então este fungo tinha sido relatado apenas na Ásia (China, Índia e Sri Lanka). Portanto, este é o primeiro relato deste fungo nos Neotrópicos.
