New cercosporoid fungi from the Brazilian Cerrado 2. Species on hosts of the subfamilies Coesalpinioideae, Faboideae and Mimosoideae (Leguminosae s. lat.)

摘要

The genus Passalora is divided into the morphological sections Passalora, Phaeoramularia, Mycovellosiella and Pseudophaeoisariopsis. New cercosporoid hyphomycetes are described from the Brazilian Cerrado on native plants of the subfamilies Mimosaoideae (Cercospora mimosae-sensitivae), Faboideae (Passalora sect. Mycovellosiella: P. acosmii), and Caesalpinioideae (Passalora sect. Mycovellosiella: P. chamaecristae-orbiculatae; Passalora sect. Passalora: P. chamaecristicola, P. machaerii; Pseudocercospora: P. exilis, P. chamaecristigena, and P. luzianiensis). Furthermore, the new combinations Passalora caesalpiniae (Xi Phaeoramularia caesalpiniae), P dalbergiae (Xi Mycovellosiella dalbergiae), Pseudocercospora bonducellae (Xi Helminthosporium bonducellae) and the new name Pseudocercospora caesalpiniicola (Xi Phaeoisariopsis caesalpiniae, non Pseudocercospora caesalpiniae) are introduced.
