Plants. pedicels, ellipsoid, obovoid, or fusoid, 27 — 54 X 10 — 1 7 ju (on an average, about 37 X 13/u), with filamentous —21/j (on an average, about 6/u); walls smooth except for 2 opposing vertical rows of short, thickly set verrucules, up to Iju thick, with 2 pores at each end. Secondary uredia hypo- phyllous, subepidermal, developing on the same patches but later than the primary sori, round, —0,3 mm in diameter; peridium convex, colorless, rather firm, opening late; peridial cells isodiametric or irregularly pol


. Cryptogamic plants of the USSR. (Flora sporovykh rastenii SSSR). Plants. pedicels, ellipsoid, obovoid, or fusoid, 27 — 54 X 10 — 1 7 ju (on an average, about 37 X 13/u), with filamentous —21/j (on an average, about 6/u); walls smooth except for 2 opposing vertical rows of short, thickly set verrucules, up to Iju thick, with 2 pores at each end. Secondary uredia hypo- phyllous, subepidermal, developing on the same patches but later than the primary sori, round, —0,3 mm in diameter; peridium convex, colorless, rather firm, opening late; peridial cells isodiametric or irregularly polygonal, 8 —16X 6 —ll/u, wall up to 2 .2/li thick. Amphispores colorless, on elongate pedicels, angular-obovoid or irregularly polyhedral, 18 —40X 14 —27/lz (on an average, about 27X 18iu)with rounded or faceted corners; walls colorless, finely and densely verrucose, 1 — 4ju thick, thicker at the corners (Figure 35). Telia scattered, amphigenous, mostly hypo- phyllous. Teliospores subepidermal, inter- cellular, scattered or loosely gathered in one layer, colorless, subgloboid or ellipsoid, usually 4-celled, divided crosswise, but varying from 1 - to 4-celled, occasionally, to 7-celled, 25 — 36X 14 — 24/Li, with one pore on the outer wall of each cell; wall smooth, about 1/u thick. Uredio- and teliospores on Matteuccia struthiopteris (L.) Todaro; aecia on species of Abies (a. alba, A. cephalonica, , A. mayriajia) in culture, distribution: Europe, Asia, (USSR: Siberia; Japan),.

Todaro ( = Struthiopteris germanica Willd.) - EUROPEAN PART: Bal., , , ; CAUCASUS: W Transc, E Transc; E SIBERIA: ; FAR EAST Uss., Sakh. Aecia were produced in cultures by Eraser and Faull in Canada on Abies balsamea, by Klebahn in Europe on A. alba and A. cephalo
