(After Tubeuf.) marked deformation of leaves, petioles, and even (though rarer) fruits of Pyrus Aucuparia and Aronia rotundifolia, both in the lowlands and mountains. I have produced Roestclia cornuta on Pyrits Aucuparia by artificial infection with portions of spore-cushions from twigs of juniper, and have observed a mountain ash in closed forest, with abundant Roestclia, directly beneath an overhanging juniper with diseased needles.
