ABSTRACT
Genus Coltricia is re-evaluated in Brazil and 10 species are accepted, namely C. barbata, C. cinnamomea, C. duportii, C. focicola, C. globispora, C. hamata, C. montagnei, C. perennis, C. permollis and C. velutina. Coltricia focicola and C. montagnei are reported respectively for the first time from South America and Brazil. Coltricia permollis and C. velutina are described as new species. Description of the new species, illustrations and a key to species of Coltricia known from the Neotropics are provided. The current knowledge of the genus in Brazil is discussed.

Fuscoporia bifurcata is described from southern Brazil based on collections from mangrove areas on Santa Catarina Island, in the state of Santa Catarina. The new species is characterized by hymenial setae with a bifurcate or spiny apex. A description with illustrations, an updated key to species of Fuscoporia from southern Brazil and a key to species of Hymenochaetaceae reported from mangroves are provided.

During fieldwork in Guyana several unusual and distinctive taxa of polypores were collected, three of which are described here as new. The first of these, Amauroderma coltricioides is the first species known in the Ganodermataceae with smooth basidiospores. Coltricia verrucata and Coltriciella navispora also are described as new, and a key to the neotropical species of Coltricia is provided. Finally, a checklist of 73 poroid fungi from Guyana is given, of which 29 are new records for the country.
ABSTRACT
Antrodiella dentipora, Ceriporia albobrunnea, C. cystidiata, Diplomitoporus allantosporus, D. stramineus, D. venezuelicus, Flabellophora fasciculata, Navisporus perennis, Nigroporus macroporus, Polyporus albostipes, Rigidoporus aurantiacus, Skeletocutis microcarpa, Tinctoporellus isabellinus, Trametes olivaceopora, T. supermodesta, Trichaptum variabilis, Tyromyces neostrigosus, T. polyporoides and Wrightoporia roseocontexta are described as new. Keys to all, except Trametes, the new neotropical species in their respective genera are included. The combinations Trichaptum griseofuscens (Mont.) Ryvarden & Iturriaga, and Tyromyces americanus (D. Reid) Ryvarden & Iturriaga are proposed.
