CALIDION BOMBACIS, A NEW COMBINATION FOR UREDO BOMBACIS WITH THE RECORD OF BOMBACOPSIS GLABRA (BOMBACACEAE) AS A NEW HOST FROM BRAZIL

The new combination Calidion bombacis is proposed for the rust species formerly known as Uredo bombacis. This nomenclatural change is based on the examination of newly collected material of this fungus from a new host, Bombacopsis glabra from Brazil, and reexamination of the isotype. Until now this fungus was only known to occur in Asia (China, India and Sri Lanka). Therefore, this is also the first record of this fungus from the Neotropics.
