| Abstract: | Based on a recent fieldwork in Panama, 25 species of rust fungi and several new hosts are reported for the first time from this country. Among the new records is one new species, Dicheirinia panamensis on Cojoba rufescens (Fabaceae). It differs from known species in the genus Dicheirinia by the presence of uredinia and telia without paraphyses, irregularly tuberculate urediniospores with two germ pores on the flattened sides, and tuberculate teliospores formed by three probasidial cells, subtended by a pedicel with three hyaline, apical cells. Taxonomical novelty: Dicheirinia panamensis J.R. Hern.,M. Piepenbr. and Vega Rios. |
