Summary The cytology of teliospore germination and basidiospore formation inUromyces appendiculatus var.appendiculatus was characterized with light and fluoroscence microscopy. Meiosis of the diploid nucleus occurred in the metabasidium. The four haploid daughter nuclei migrated into the basidiospore initials where they underwent a post meiotic mitosis. Each basidiospore was delimited from the meatabasidium by a septum at the apex of the sterigma. Seventy-five percent of mature basidiospores were binucleate, 24.5% uninucleate, and 0.5% trinucleate. Mature, released basidiospores measured ∼ 16×9 Μm, were smooth-surfaced, and reniform to ovate-elliptical in shape.
