During inventory of conidial fungi at Serra da Fumaca, Pindobacu, Bahia State, and Brazil, 44 species were found. Five species are new records for Americas: Dendryphiosphaera parvula Nawawi & Kuthub., Diplococcium dendrocalami Goh, K.D Hyde & Umali, Sporidesmiella aspera Kuthub. & Nawawi, S fusiformis W.P. Wu, and Triposporium verruculosum RF Castaneda, Gene & Guarro. Stanjehughesia hormiscioides (Corda) Subram. is a new record for Neotropics; Hemibeltrania decorosa RF Castaneda & WB Kendr. is a new record for South America and Spadicoides macroobovata Matsush is a new record for Brazil. Descriptions, illustrations, geographical distribution and comments are presented for new records. A list of species founded is included too.

Alguns fungos conidiais aquáticos-facultativos do bioma Caatinga

During study of conidial fungi on submerged plant debris in Serra da Fumaca and Serra da Jiboia, Bahia, 17 species were identified. These species included five new records: Actinocladium verruculosum for the American continent, Xylomyces aquaticus for the Neotropics, Actinocladium longiramosum and Dischloridium inaequiseptatum for South America and Cacumisporium pleuroconidiophorum for Brazil. Descriptions, illustrations, geographic distributions and comments are provided for the aforementioned species and a list of all of the species is included.

New species and combinations of conidial fungi from the semi-arid Caatinga biome of Brazil

During a survey of conidial fungi carried out in aquatic and terrestrial habitats in the semi-arid Caatinga biome of Brazil, three new species were found on decaying plants. Anungitopsis caatingensis sp. nov. was found on decaying leaves collected in a terrestrial habitat. Codinaea pindobacuensis sp. nov. and Stanjehughesia clavata sp. nov. were found on decaying leaves and decaying bark collected in freshwater, respectively. Descriptions, illustrations and comments are presented, including a key to accepted species of Anungitopsis. Three species of Janetia are transferred to Linkosia and two species are proposed as synonyms: Minimelanolocus machili is synonymous with Cacumisporium pleuroconidiophorum and Janetia curviapicis is synonymous with Stanjehughesia hamatiella.

Conidial fungi of Caatinga biome II. New records for American continent, Neotropics, South America and Brazil

During investigation of conidial fungi from dead plant material in an area of extreme biological importance at Caatinga biome, municipality of Morro do Chapeu, Bahia State, Brazil, some new records for American continent, South America, Neotropics, and Brazil were found. Dendryphiopsis biseptata Morgan-Jones, R.C. Sinclair & Eicker and Virgariella atra S. Hughes are new records for American continent; Dictyochaeta matsushimae (Hewings & J.L. Crane) Whitton, McKenzie & K.D. Hyde and Endophragmiella boothii (M.B. Ellis) S. Hughes are reported for the first time for Neotropics; Anungitea palustris R.F. Castaneda & W.B.

Taxonomy and molecular phylogeny of Diatrypaceae (Ascomycota, Xylariales) species from the Brazilian semi-arid region, including four new species

Members of the Diatrypaceae are predominantly saprotrophic on the decaying wood of angiosperms worldwide and the family has received little attention due to its difficult taxonomy. However, the recent detection of several pathogenic species, once considered saprotrophic, associated with the wood of diseased grapevines has increased interest in this family. The diversity of tropical species is less well known and more poorly sampled in phylogenetic studies than temperate species. In the present study, we investigated the diversity of diatrypaceous fungi from three areas in the Brazilian semi-arid region and performed phylogenetic analyses of the family based on the entire internal transcribed spacer (ITS) region and partial ß-tubulin gene. Twenty-eight new ITS and 19 new ß-tubulin sequences were generated, representing eight species distributed in five clades. Diatrypella atlantica, Eutypa guttulata, Eutypella cearensis, and Peroneutypa diminutispora are proposed here as new species, while Eutypella microtheca and P. curvispora are new records for Brazil. All eight species are described, illustrated, and discussed.
