Some hyphomycetes from Brazil. Two new species of Brachydesmiella, two new combinations for Repetophragma, and new records

Brachydesmiella brasiliensis anam. sp. nov., found on decaying pods of unidentified Leguminosae and Brachydesmiella obclavata anam. sp. nov., collected on the rotten leaf of an unidentified plant, both from the semi-arid region of Bahia State, Brazil, are described and illustrated. The former is distinguished by navicular to broad fusiform, 3-euseptate, densely verrucose, brown conidia; the latter by obclavate, rostrate, 1-euseptate, pale brown, smooth-walled conidia. A key to Brachydesmiella species is provided. Repetophragma fasciatum comb. nov. and Repetophragma filiferum comb. nov. are proposed. Some other microfungi are reported from the semi-arid region of Brazil.
