Puccinia pachyderma. [Descriptions of Fungi and Bacteria].
Abstract A description is provided for Puccinia pachyderma. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Rust of Gagea species only. HOSTS: Gagea bulbifera, G. chlorantha, G. gageoides, G. maeotica, G. olgae, G. pusilla (Liliaceae). GEOGRAPHICAL DISTRIBUTION: ASIA: Azerbaijan, Iran, Turkmenistan. EUROPE: Russia (Rostov, Samara, Saratov, Voronezh), Ukraine. TRANSMISSION: No detailed studies have been reported; teliospores are presumably dispersed by air currents and then germinate to produce basidia with basidiospores, which re-infect the host plants; the fungus might also survive in bulbs of the infected plant.
