Sori hypophyllous, scattered or rather crowded, often uniformly distributed over the whole surface of the leaf, rarely confluent, sur- rounded by the torn epidermis, pulverulent, reddish-brown; spores ellipsoid, oblong or pyriform, rounded at both ends, hardly thickened above, but with a minute papilla, much constricted, minutely verruculose, Fig. 148. P. Epilobii. ' J Teleutospores. clear brown, 2t—48x16—25 fx : pedicels hyaline, 10—16/x long. On Epilobiiiin palustre. Rare. May—August. A sub- alpine and arctic species. (Fig. 148.) Distinguished from P. pulrrrvJenta not only by its spores and the absence of the secidium- and uredo-stages, but also by the smaller teleuto- sori which are scattered pretty uniformly over the leaf-surface. The mycelium seems to be perennial ; it permeates the whole plant, and somewhat deforms the shoots, making the leaves smaller and thicker. The warts of the epispore are sometimes hardly perceptible, but can usually be seen if the spore is squeezed in the way recommended, see p. 83. Distribution : Central and Northern Europe. 73.
