Spermatia — — Aecia hypophyllous on leaves of current year, cylindrical, — across, up to mm high, white; outer wall of peridial cells smooth, — thick; inner wall densely and rather coarsely verrucose, 3 — 6ju thick. Aeciospores broad-ellipsoid, ovoid, or subgloboid, white, 19 — 24 X 16 —22/j (on an average, 21 X 17ju); spore wall densely and rather coarsely warted, colorless, /j thick. Primary uredia hypophyllous on discolored spots, subepidermal, round, — mm in diameter; peridium colorless, delicate; peridial cells isodia- metric to irregularly angular, somewhat elongate toward the peridial base. Urediospores white in mass, on very short pedicels, ellipsoid, obovoid, or fusoid, 24 —46 X 8 —13iu (on an average, 31 X lOju ), mucronate, narrowly conical at apex and broad at the base, 0—22/u long (on an average, 12 ju); spore wall thin, less than 1/u, smooth, except for a few flat verru- cules; in many spores lateral walls considerably thickened, up to 3/Li. Secondary uredia develop later than the primary ones and resemble them but open late. Urediospores (amphi- spores) colorless, on long pedicels, obovoid, or irregularly angular, 14 —30X 8 —22/LX (on an average, 21 X 13)Lj), without wings or prongs, walls densely and finely warted, colorless, — ^ thick. Teliospores scattered, usually hypophyllous, subepidermal, intercellular, subgloboid to ellipsoid; usually 2-celled, rarely 1-celled, 14 —22)u across; spore wall colorless, about In thick (Figure 30). Uredio- and teliospores on Dryopteris phegopteris (L.) C. Christ. ( = Phegopteris vulgaris Mett., Nephrodium phegopteris Baumg.) almost throughout Europe and in Japan.
