JEcidiospores. ^Ecidia hypophyllous, on round yellow or brownish spots, in roundish clusters 2—5 mm. diam., shortly cylindrical, whitish-yellow, with recurved irregularly torn margin; spores delicately verruculose, orange, 16—27 /x. Uredospores. Sori epiphyllous, scattered, minute, oblong, yellow; spores globose to ellipsoid, echinulate, yellow-brown. 22—30^, without Fig. 196. P. Festucae. Teleutospores and mesospore. Teleutospores. Sori hypophyllous, minute, scattered, oblong or sublinear, black-brown; spores clavate-oblong, crowned at the summit, with four to six curved and sometimes bifid processes, gently constricted, attenuated downwards, smooth, pale-brown, 40—60 x 15—23 ft; pedicels brown, persistent, 15—25 //, long: a few mesospores intermixed. iEcidia on leaves of Lonicera Periclymenum, June—August,, not uncommon; uredo-and teleutospores on Festuca duriuscula, F. ovina, August—October, not common or at least rarely observed. (Fig. 196.) It was Plowright who first, in 1890 (after twenty-eight unsuccessful trials), proved that the well-known secidium on Lonicera was connected. G. U. 17.
