Aecia on young shoots erumpent from under cortex, also on stems and needles of seedlings, mainly solitary, lineate, varying in size, up to 2 cm long and 3 mm wide; on needles small, 1 —2 mm long, reddish-orange. Aeciospores mainly globoid or ovoid, 14—20X13 —17fx, rarely oblong in section, 22 X lO/u; wall evenly thickened, about 2m, or with thickenings up to 4/J, verruculose; warts in the form of very short ridges, less than fx thick, at approximately intervals. Uredia hypophyllous, solitary or in groups, spread over the entire frond, small, about mm, causing the appearance of yellow spots on the corresponding upper side of the leaf. Urediospores mostly ovoid, often slightly tapering at one end, rarely globoid or ellipsoid, 15-22X11-16^ (according to Rostrup, 22 —27 X 12 —1 9m); wall usually with thickenings up to 5 — 6m at both ends of the spores arranged in rows along their tapered ends, sometimes uniformly thick (2 m), sparingly verrucose (at 2—3m intervals). Paraphyses uniformly spread over the sori, 40—50m long, capitate, heads 12 —17 m wide, 20—25m high, tapering into the thin (3—4m) pedicels; wall 3—7m thick. Telia hypophyllous, s
