Item First report of Gilbertella persicaria as the cause of soft rot of fruit of Syzygium cumini(Australasian Plant Disease Notes, 2014-12) Pinho, Danilo B.; Pereira, Olinto L.; Soares, Dartanha J.A zygomycetous fungus causing fruit soft rot was found on Sygyzium cumini in Northeast Brazil. Based on morphological and phylogenetic analyses, the fungus was identified as Gilbertella persicaria. This is the first report of this fungus causing the decay of S. cumini fruit worldwide.Item Naming potentially endangered parasites: Foliicolous mycobiota of Dimorphandra wilsonii, a highly threatened Brazilian tree species(Plos One, 2016-02-24) Silva, Meiriele da; Pinho, Danilo B.; Pereira, Olinto L.; Fernandes, Fernando M.; Barreto, Robert W.A survey of foliicolous fungi associated with Dimorphandra wilsonii and Dimorphandra mollis (Fabaceae) was conducted in the state of Minas Gerais, Brazil. Dimorphandra wilsonii is a tree species native to the Brazilian Cerrado that is listed as critically endangered. Fungi strictly depending on this plant species may be on the verge of co-extinction. Here, results of the pioneering description of this mycobiota are provided to contribute to the neglected field of microfungi conservation. The mycobiota of D. mollis, which is a common species with a broad geographical distribution that co-occurs with D. wilsonii, was examined simultaneously to exclude fungal species occurring on both species from further consideration for conservation because microfungi associated with D. wilsonii should not be regarded as under threat of co-extinction. Fourteen ascomycete fungal species were collected, identified, described and illustrated namely: Byssogene wilsoniae sp. nov., Geastrumia polystigmatis, Janetia dimorphandra-mollis sp. nov., Janetia wilsoniae sp. nov., Johansonia chapadiensis, Microcalliopsis dipterygis, Phillipsiella atra, Piricauda paraguayensis, Pseudocercospora dimorphandrae sp. nov., Pseudocercosporella dimorphandrae sp. nov., Ramichloridiopsis wilsoniae sp. and gen. nov., Stomiopeltis suttoniae, Trichomatomyces byrsonimae and Vesiculohyphomyces cerradensis. Three fungi were exclusively found on D. wilsonii and were regarded as potentially threatened of extinction: B. wilsoniae, J. wilsoniae and R. wilsoniae.Item Reappraisal of the black mildews (Meliolales) on Hevea brasiliensis(Tropical Plant Pathology, 2014-01) Pinho, Danilo B.; Honorato Junior, Jaime; Firmino, André L.; Hora Junior, Braz T.; Mizubuti, Eduardo S. G.; Pereira, Olinto L.The rubber tree (Hevea brasiliensis) is host to several fungal species, including Irenopsis heveae as described by Hansford in 1961, which causes black mildew on leaves. One specimen of Irenopsis heveae from the state of Espírito Santo and two from the state of Pará were analyzed and showed some morphological differences. Some structures are similar to morphological characteristics as described and illustrated by Vincens in 1915 for Meliola heveae. Morphological comparisons with the type specimen of I. heveae and the alignment of the nucleotide sequences of the 28S rDNA region, however, indicate that the three samples belong to the same species. According to these data M. heveae and I. heveae are heterotypic synonyms with M. heveae being the older name. As the name I. heveae is already occupied by Hansford, Irenopsis vincensii is proposed as new name for the black mildew on H. brasiliensis. This is the first contribution of molecular sequence data for this species.
