Two new species in a new genus and a critical revision of Brachybasidiaceae (Exobasidiales, Basidiomycota) in honor of Franz Oberwinkler

The Brachybasidiaceae are a family of 22 known species of plant-parasitic microfungi belonging to Exobasidiales, Basidiomycota. Within this family, species of the largest genus Kordyana develop balls of basidia on top of stomatal openings. Basidial cells originate from fungal stroma filling substomatal chambers. Species of Kordyana typically infect species of Commelinaceae. During fieldwork in the neotropics, fungi morphologically similar to Kordyana spp. were found on Goeppertia spp. (syn. Calathea spp., Marantaceae), namely on G. panamensis in Panama and on G. propinqua in Bolivia. These specimens are proposed as representatives of a genus new to science, Marantokordyana, based on the distinct host family and molecular sequence data of ITS and LSU rDNA regions. The specimens on the two host species represent two species new to science, M. oberwinkleriana on G. panamensis and M. boliviana on G. propinqua. They differ by the size and shape of their basidia, molecular sequence data of ITS and LSU rDNA regions, and host plant species. In the past, the understanding of Brachybasidiaceae at order and family level was significantly improved by investigation realized by Franz Oberwinkler and his collaborators at the University of Tübingen, Germany. On species level, however, our knowledge is still very poor due to incomplete species descriptions of several existing names in literature, scarceness of specimens, as well as sequence data lacking for many taxa and for further barcode regions. Especially species of Kordyana and species of Dicellomyces are in need of revision.

“…Ceratobasidium niltonsouzanum can be differentiated from certain species based on morphological markers. The production of four basidiospores per basidium separate this species from C. tradescantia, which forms two basidiospores per basidia (Macedo et al 2016). Ceratobasidium tradescantia, related to T. fluminensis in Brazil, also presents hymenium on host leaves.…”

White thread blight is one of the most common diseases affecting several tree species that grow in warm and humid regions. The typical symptoms of this disease include blighted leaves hanging by a white thread of fungal hyphae. Leaf samples exhibiting white thread blight symptoms were collected from neem (Azadirachta indica A. Juss) and Brazilian cherry pitanga (Eugenia uniflora L.) plants in Northeastern Brazil, and from Indian green-tea (Camellia sinensis (L.) O. Kuntze), coffee (Coffea arabica L.), and persimmon (Diospyros kaki L.) in agricultural areas neighboring the Atlantic forest in Southeastern Brazil. Fungal isolates were obtained indirectly from leaf fragments or directly by transferring mycelia and sclerotia to culture medium. Bright field and scanning electron microscopy images revealed the association of Rhizoctonia-like hyphae and basidiospores with the infected leaves. In pathogenicity tests, Rhizoctonia-like fungal isolates induced leaf necrosis on their hosts, and the pathogens were reisolated from inoculated plants. Phylogenetic analyses based on sequences of the ITS rRNA region indicated the occurrence of Ceratobasidium lineages distinct from previously reported Ceratobasidium species. Our study leads to the description of two new species of Ceratobasidium: the fungal isolates from A. indica, C. sinensis, and E. uniflora were classified as Ceratobasidium niltonsouzanum sp. nov., and those obtained from C. arabica and D. kaki as Ceratobasidium chavesanum sp. nov.

“…There are only four published records of A. rolfsii attacking members of the Commelinacea worldwide, namely: on Commelina benghalensis in Tonga (Dingley et al 1981), on Dichorisandra sp. in Florida (Farr and Rossman 2016), on Zebrina pendula in Hawaii (Farr and Rossman 2016) and on Tradescantia fluminensis in Brazil (Macedo et al 2016). Athelia rolfsii is a generalist plant pathogen known to be an important pathogen of various crops (Harlton et al 1995) and, thus, is of no interest for biocontrol.…”

“…Several arthropods species have already been introduced against T. fluminensis in New Zealand (Fowler et al 2013). Also, the fungus Kordyana brasiliensis, recently described by Macedo et al (2016), is being evaluated for its release in Australia and New Zealand (Morin 2015). The use of natural enemies collected in the native range of TS in the Old World (classical biological control) is an attractive alternative for biological control, providing they are damaging to, co-evolved with, and host-specific to TS, and have remained restricted to those areas.…”

Commelina benghalensis (tropical spiderwort-TS) is an invasive herbaceous plant, native to South and Southeast Asia and one of the worst agricultural weeds in the tropics. Its management is notoriously difficult because of its ability to regenerate from small fragments and its tolerance to glyphosate applications. There are no published records of biocontrol attempts against TS involving either microbial or arthropod natural enemies. Prior to investigating classical biocontrol agents, surveys have been conducted in Brazil and, more recently, concentrated in Viçosa (state of Minas Gerais) to determine whether fungal pathogens of TS are already present. Five different fungal pathogens were collected. These fungi were identified as causing the following diseases: Athelia rolfsiicrown rot, Cercospora cf. sigesbeckiaeleaf spots, Corynespora cassiicolaleaf spots, Neopyricularia obtusa sp. nov.leaf spots and Rhizoctonia solaniblight. One of the fungi found on TS represents a new taxon, and the others represent either a new host association, a new geographic record or both, except for Corynespora cassiicola, which has already been recorded as able to attack TS (ex-tomato isolates, under controlled conditions) in Brazil. The mycobiota identified in Brazil is limited and lacks many of the TS-specific fungal pathogens recorded in Africa and Asia, namely: Kordyana celebensis, Kordyana indica, Phakopsora tecta, Puccinia commelinae, Uredo ochracea, Bauerago combensis and Bauerago commelinae. It is conjectured here, that such exotic fungi, may offer a valuable resource for management of one of the worst agricultural weeds in Brazil and in the tropical world, and require investigation as biological control agents for introduction in Brazil.
