摘要: Seven new species of smut fungi from the neotropics are described. The remarkable for their special morphological development, as representatives small genera, or by interesting host plants and contribution to our knowledge neotropic biodiversity. Aurantiosporium pallidum Bolivia is third known in its genus. Its sori develop hypertrophied tissue rachillae female male spikelets. Kuntzeomyces ruizianae Colombia second genus, characterized relatively teliospores. Moreaua bulbostylidis Venezuela first record a this genus (formerly Tolyposporium) on Bulbostylis (Cyperaceae).
