. Cryptogamic plants of the USSR. (Flora sporovykh rastenii SSSR). Plants. usually slightly broader at the apex, often oblong-obovoid, 22 — 33 X 12 — 1 3/u; wall up to 3fx thick, sometimes with thinner spots, distantly verrucosa (interspaces 2—3^), smooth and usually thinner at the apex. Paraphyses 50 — 70/x long, capitate, on thin pedicels (3 — 5/Lt), heads 15 —20/u, occasionally digitate, with tapering heads (lO —15^) and thickened pedicels (7^); walls evenly thick, 3—5jli. Telia mostly epiphyllous, less frequently hypophyllous, arising between the cuticle and epidermis, in groups or solitar

Telia mostly epiphyllous, less frequently hypophyllous, arising between the cuticle and epidermis, in groups or solitary, scattered frequently over the entire leaf surface, — ^ wide, dark brown. Teliospores irregularly prismatic, rounded at both ends, usually more elongate on the upper side of the leaf, 30 —48 X 7 — 14 /:/; spore wall light brown, about 1 ju thick, not thickened at apex; pore not evident (Figure 1 37). Basidiospores orange-colored. Heteroecious. Aecia on species of Allinum. Uredio- and teliospores on Salix fragilis L., S. pentandra L., S. fragilis X pentandra. The fungus is morphologically indistinguishable from Melampsora galanthi-fragilis Kleb. General distribution: Europe. On Allium cepa L. and on Allium oleraceum L. — EUROPEAN PART: (Kursk Region: Borisov District). On Salix fragilis L. - EUROPEAN PART: U. Dnp. (Smolensk Region), M. Dnp. (Belaya Tserkov; Kursk Region: Borisov District), U. V. (Kaluga), Transv. (Buguruslan), (Voronezh, Zadonsk, Tambov), L. Don. (Lebedyan), Bl. (Gornostaevka). According to Klebahn (l. c.) basidiospores from Salix fragilis L. infected Allium vineale L., A. sativum L., A. schoenoprasum L., A. ascalonicum L., A. ursinum L.; weakly infected A. porrum L., failed to infect A. Moly L. and Galanthus nivalis L. Aeciospores from Allium vineale L. and A. schoeno- prasum infected Salix fragilis L., S. pentandra L. and S. fragilis X pentandra; failed to infect S. alba L., S. amygdalina L., S. alba X amygdalin
