Abstract

This paper aims to present the Pucciniales found in paramos of Antioquia on the Cyperaceae family. Collections were made of parasitized plants by Pucciniales in páramos of Antioquia Department with altitudes from 2800 to 4050 masl.; of the 136 collected materials, a total of 18 belonged to the Cyperaceae family. The spore states were observed under the stereomicroscope to have information about sori and from there micropreparations were made in lactoglycerin through free-hand sections and scrapings, 40 measurements were made of each of the structures found under the microscope and images were taken with a digital camera coupled. Results obtained include the description of the new species Puccinia sonsonensis; the first registration for Colombia of Puccinia caricina, Puccinia dioicae and Puccinia cephalotes, and first time record of species of the genus Carex parasitized by rust in Colombia. The results provide a additional argument the urgency of preservation and continuous study for such areas.
