Summary of Invasiveness

Top of page

There is little published information on this plant pathogenic fungus, which has limited geographic distribution. As hosts exist in other regions of the world with similar environmental conditions, this species may pose a threat to native or agricultural plants if introduced.

Description

Top of page

Spermogonia on current-year needles, amphigenous, subcuticular, hemispherical or conical, with flat hymenia, 85-150 µm diameter, 55-75 µm high, yellow-orange changing to brown; spermatia oblong-ellipsoid to ellipsoid, 4.0-5.0 x 1.5-2.0 µm, colourless. Aecia on current year needles, hypophyllous, cylindrical, 0.2-0.3 mm wide, 0.5-1.5 mm long, orange; peridial cells colourless, firm, rupturing at the apex; peridial cells oblong-ellipsoid to ellipsoid, 30-93 x 12-23 µm, overlapping, inner walls 2.0-2.5 µm thick, verrucose with striae, outer wall 1.5-2.0 µm thick, finely verrucose; aeciospores ellipsoid, obovate or subglobose, 20-27 x 13-20 µm, densely verrucose, occasionally with a reticulum-like area resulting from fused verrucae, 0.5-1.5 µm high, contents yellow. Uredinia hypophyllous, subepidermal, scattered, or rarely grouped, often thickly, scattered over the whole leaf surface, round, minute, 0.1-0.2 mm diameter, pale-yellow, at least somewhat pulverulent; peridia hemispherical, delicate, rupturing at apex; upper peridial cells small, isodiametrically to irregularly polygonal, 8-22 µm wide, lateral ones radially elongate, walls of peridial cells thin, 1-2 µm thick, smooth, nearly colourless; ostiolar cells globose or ellipsoid, walls rather thick, 2-4 µm, smooth, colourless; urediniospores obovate, ellipsoid or oblong, 18-27 x 10-16 µm, walls 1.2-1.5 µm thick, uniformly echinulate, nearly colourless, four to seven germ pores, bizonate, contents orange-yellow. Telia hypophyllous, subepidermal, minute, in dense clusters limited by veins, brownish-yellow; teliospores intercellular, solitary or grouped, often compacted laterally under epidermis, oblong or polygonal, 1-7-septate, 18-30 x 12-24 µm, smooth, pale-brownish. Basidiospores globose, 5-8 µm diameter, cytoplasm pale-yellow. See Kaneko and Hirastuka (1981) and Hirastuka et al. (1992) for more detailed descriptions.
