Fungos conidiais na Caatinga: espécies associadas ao folhedo

An inventory of conidial fungi was carried out in six areas of extreme biological importance within the Caatinga biome. Seventy four species were collected, with seven new records for Brazil. Heliocephala zimbabweensis Decock, V. Robert & Masuka is recorded for the second time for the world, Sporidesmium verrucisporum M.B. Ellis is new to the American continent, Dicyma vesiculifera Piroz., Fusariella concinna (Syd.) S. Hughes, F. obstipa (Pollack) S. Hughes, Phaeostalagmus tenuissimus (Corda) W. Gams and Sporidesmiella claviformis P.M. Kirk are new to South America; Falcocladium sphaeropedunculatum Crous & Alfenas, Myrmecridium schulzeri var. schulzeri (Sacc.) Arzanlou, W. Gams & Crous, Pseudodictyosporium wauense Matsush. and Repetophragma inflatum are new to the Brazilian semi-arid region. Four species were recognized as new, Brachysporiellina fecunda S.M. Leao, A.C. Cruz, R.F. Castaneda & Gusmao, Diplococcium verruculosum A.C. Cruz, Gusmao & R.F. Castaneda, Lobatopedis longistriatum A.C. Cruz, Gusmao, S.M. Leao-Ferreira & R.F. Castaneda, Subramaniomyces pulcher A.C. Cruz, Gusmao & R.F. Castaneda and were published separately. The new records are described, illustrated and commented. A list including all other collected species is presented.

Fungos anamórficos (Hyphomycetes) da Chapada Diamantina: novos registros para o Estado da Bahia e Brasil

(Anamorphic fungi (Hyphomycetes) from the Chapada Diamantina: new records from Bahia State and Brazil). The anamorphic fungi are characterized by production of asexual reproductive structures and are common inhabitants of the leaf litter, where they play an important role in decomposition. The aim of this work was to survey the anamorphic fungi associated with leaf litter from Chapada Diamantina, B ahia state. Thirteen expeditions took place from December/2002 to October/2003 to collect leaf litter. The serial washing technique with sterile distilled water followed by incubation in moist chambers was utilized to verify the presence of anamorphic fungi. Permanent slides of the reproductive structures of specimens were prepared with PVL resin and deposited at the HUEFS Herbarium. Of the 57 species of anamorphic fungi identified, nine represent new records in Bahia state, and five in Brazil, as follows: Fusariella atrovirens (Berk.) Sacc., Kiliophora ubiensis (Caneva & Rambelli) Kuthub. & Nawawi, Paraceratocladium silvestre Castaneda, Pleurotheciopsis setiformis Castaneda and Triscelophorus deficiens (Matsush.) Matsush. Comments and geographic distribution are included for the new records in Bahia; descriptions and illustrations of the new records in Brazil are presented.

Forty one species were identified: Dactylaria cazorlii Mercado, Gene & Guarro and Thozetella queenslandica Paulus, P.Gadek & K.D. Hyde are described the second time for science; Ellisembia bambusae (M.B. Ellis) W.P. Wu, Gonytrichum mirabile Hol.-Jech., Uberispora tropicalis Bhat & W.B.

Stewart, Piricauda cochinensis (Subram.) M.B. Ellis, Taeniolella alta (Ehrenb.) S. Hughes are new records for South America; Sporoschisma saccardoi E.W. Mason & S. Hughes and Stachylidium bicolor var. bicolor Link are new records for Brasil and Paraceratocladium bacilliformis Calduch, Stchigel, Gene & Guarro is a new record for the Brazilian semi-arid region. The new records are described, illustrated and commented and a check list with all species found is included.

O gênero Exserticlava (Fungo Anamorfo - Hyphomycetes) no Brasil

The genus Exserticlava (Anamorphic Fungi - Hyphomycetes) from Brazil). Exserticlava triseptata (Matsush.) S. Hughes and E. vasiformis (Matsush.) S. Hughes, are described and illustrated as new records for Brazil. Comments and geographical distribution are also presented.

Cryptophiale and Cryptophialoidea (Conidial fungi) from Brazil and keys to the genera

During a survey of microfungi associated with dead leaves in the State of Bahia, Brazil, four species of Cryptophiale Piroz. and two species of Cryptophialoidea Kuthub. & Nawawi were found. Cryptophiale guadalcanalensis Matsush. and Cryptophialoidea fasciculata Kuthub. & Nawawi are new records for the neotropics, while C. ramosa Delg.-Rodr., J. Mena & Gene is a new record for South America. Descriptions, illustrations and geographical distribution of all the fungi are provided.

Scolecobeltrania, an interesting new microfungus from Venezuela

A new microfungus collected on dead plant material from the “Cerro El Ávila” mountain range and “Parque Nacional Canaima” tropical forest in Venezuela is described and illustrated. Scolecobeltrania vermispora gen. & sp. nov. is characterized by macronematous branched conidiophores, polyblastic conidiogenous cells, and unicellular vermiform to sigmoid pale brown conidia with up to 11 hyaline transverse bands.

The genus Stachybotrys (anamorphic fungi) in the semi-arid region of Brazil

(O genero Stachybotrys (fungos anamorficos) na regiao semi-arida do Brasil). Stachybotrys e caracterizado por apresentar conidioforos macronematicos, mononematicos simples ou ramificados, celulas conidiogenicas evidentes, terminais e fialidicas e conidios asseptados, reniformes, elipsoides a esfericos, lisos ou verrucosos, produzidos em mucilagem. No Brasil ja foram relatadas oito especies, ocorrendo no solo, no ar e em material vegetal em decomposicao. Durante investigacao de fungos conidiais associados a serapilheira em areas do semi-arido brasileiro foram encontradas nove especies: S. bisbyi (Sriniv.) G.L. Barron, S. chartarum (Ehrenb.) S.
