Teliospores mostly hypophyllous, subepidermal, colorless, subgloboid to ellipsoid, 2- to 4-celled, 16 — 24 X 16—20/j; spore wall colorless, smooth, about 1 ju thick. On species of Athyrium (A. multifidum Rosenst. ( = A. deltoideofrons Mak.), A. otophorum (Miq.) Koidz., A. i:igescens Mak., (Franch. et Sav.)) in Japan. Distinguished from Uredinopsis athyrii Kamei only by development of amphispores. Faull (, p. 38) found the latter only on Athyrivim multifidum, but held that amphispores might be found also on A. melanolepis; while Uredinopsis daisenensis should be referred to the synonym U. athyrii.
