New species of Meliola and Irenopsis (Ascomycota: Sordariomycetes) found in Bahia, Brazil. In: Agrotrópica v. 33 n. 3 p. 173-180, 2021.

Abstract

Meliola Fr. and Irenopsis F. Stevens are fungal genera classified as Fungi, Dikarya, Ascomycota, Pezizomycotina, Sordariomycetes, Meliomycetideae, Meliolales and they are agents of black mildews on plants. Meliola is the largest genus within the group and Irenopsis is the fourth largest. Representatives of these fungi were collected on leaves of Croton urucurana Baill., Clitoria fairchildiana R.A. Howard and Myrsine sp. in the following Bahian municipalities: Santa Teresinha, Cruz das Almas and Barra da Estiva, respectively. Permanent and semi- permanent microscopic preparations were used for the morphological characterization of the three fungi. As their characteristics did not fit any described species, the following new species: Meliola crotonifolia, M. myrsines and Irenopsis cruzalmensis are proposed to designate them.
