Ingoldian fungi are aquatic hyphomycetes that presents conidia sigmoid or branch and occur in lotic and lentic environment, being easily found in foam of water bodies. Aiming to contribute to the knowledge of the biodiversity of Ingoldian fungi in semiarid region, was conducted an inventory in water bodies of areas of extreme biological importance of the Brazilian semiarid. In a single expedition, samples of foam and submerged leaves were collected in water bodies of four localities in semiarid region (Brejo Paraibano-PB, Serra da Jibóia-BA, Chapada do Araripe and Serra de Ibiapaba-CE). The samples of foam were collected and packaged in plastic bottles of 250 mL and the submerged leaves were packaged in plastic bags. In “Laboratório de Micologia“(LAMIC), the foam was homogenized and 200 µL of each sample were transferred to 30 slides, which were exposed at room temperature to evaporation. After evaporation, was addition of one drop of lactic acid and sealed with nail polish. Samples of submerged leaves were subjected to the technique of washing in flowing water and cut into pieces of 1 cm², that were placed in petri dishes containing distilled sterile water for observation of fungi. The bottles and slides were deposited in the “Herbário da Universidade Estadual de Feira de Santana” (HUEFS). The pure cultures were deposited in the “Coleção de Cultura de Micro-organismos da Bahia” (CCMB). The first chapter presents all 27 taxa of Ingoldian fungi found in the study, 23 of these taxa present description, geographic distribution, taxonomic comments and illustration; 22 are new records: american continent (3), Neotropics (1), South America (3), Brazil (5), Brazilian semiarid region (7), Ceará (2) and Paraíba (1). The second chapter shows all species of the genus Campylospora with descriptions, comments, geographical distribution, a key to the genus and illustrations. The water body with the highest number of taxa of Ingoldian fungi was the river Missão velha.
