The genus Menisporopsis S. Hughes is characterized by synnematous conidiomata around a central seta, phialidic conidiogenous cells and falcate to lunate 0-to 1-septate conidia with terminal setulae. Currently, nine species are included in the genus. In the course of investigating conidial fungi associated with decaying plant material in the semi--arid region of Brazil, we identified five
-(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 & Gené is a new record for South America. Descriptions, illustrations and geographical distribution of all the fungi are provided.
Um inventário de fungos conidiais foi realizado em seis áreas de extrema importância biológica do bioma Caatinga. Foram identificadas 41 espécies, com Dactylaria cazorlii Mercado, Gené & Guarro e Thozetella queenslandica Paulus, P.Gadek & K.D. Hyde descritas pela segunda vez para a ciência.

-(The genus Stachybotrys (anamorphic fungi) in the semi-arid region of Brazil). Stachybotrys is characterized by macronematous, mononematous, unbranched or branched conidiophores, with discrete terminal and phialidic conidiogenous cells, and aseptate, reniform, ellipsoidal to spherical, smooth or verrucose conidia, which are produced in a slimy mass. eight species have been reported from Brazil, occurring in the soil, air and leaf litter. during investigation of conidial fungi on decaying leaf litter in semi-arid areas of Brazil nine species were found: S. bisbyi (sriniv.) g.l. Barron, S. chartarum (ehrenb.) s. hughes, S. globosa P. c. Misra & s. K. srivast., S. kampalensis hansf., S. longispora Matsush., S. nephrospora hansf., S. nilagirica subram., Stachybotrys parvispora s. hughes and S. verrucispora Matsush. Stachybotrys nilagirica is a new record from Brazil. descriptions, comments, geographic distribution and illustrations are presented for above mentioned species. a key for all species recorded in semi-arid region of Brazil is presented.
