Jun. virginicnw, and Jan. 2}hoenicea. (A reported occurrence on Finns hakpnisis is probably an error.) The sporogenous cushions are little dark-lnown protuberances which lircak fortli in sjirinp: from swellings, or on L;reen. Fig. 2^il—Gi/iiinos/>orunpium xnbinae on twigs of Junipirux Sidjimi, at the time nf lilicnitiou of spores, (v. Tubeuf i>hot.) twigs and scale-leaves. These bodies absorb water, swell, and run together, forming transparent gelatinous masses (Figs. 230 and 231). The teleutospores resemble those of G. junipcrinum, but liave only four germ-pores; they germinate on the gelatinous masses, and produce promycelia and sporidia. The latter germinate at once, chiefly on leaves of Pyrus com- munis. The pycnidia are produced on the upper epidermis as sticky yellow spots bearing darker dot-like pycnidia. The aecidia {llocstelia canccllata) are found in September on the under-surface of the leaves of pear, also on leaf-petioles, young shoots, and even on the fruits. The peridia differ from both.
