MONOGRAPH OF BASIDIOPHORA (OOMYCETES) WITH THE DESCRIPTION OF A NEW SPECIES

BARRETO, R. W. & DICK, M. W., 1991. Monograph of Basidiophora (Oomycetes) with the description of a new species. The genus Basidiophora is reviewed and a key to the species provided. Within the genus, Basidiophora entospora Roze & Cornu has the widest host range (though restricted to the Gompositae) and the widest distribution. Outside North America, it is limited to its weedy host Conyza canadensis (L.) Cronquist. Basidiophora kellermanii (Swingle) Wilson is the most distinct species, restricted to a single host, ha xanthifolia Nutt. (Compositae), occurring only in the USA. Basidiophora montana is described here, and can readily be distinguished from B. entospora. It is a parasite of Mikania micrantha H. B. K. and was found in humid subtropical highlands of Brazil (States of Rio de Janeiro and Paraná) during a survey for weed pathogens, which was initiated with the aim of seeking potential fungal biological control agents. Mikania micrantha is a very serious introduced weed in south‐east Asia and Oceania, and further work with this fungus is recommended because of its severity as a pathogen and its absence in the regions of the globe where its host is important as a weed.
