(After Nawaschin.) Hormomyia betulae Wtz. often occurs along with the above. It causes the production of thick spherical fruits with little or no wing. Sclerotinia adusta Karst. has also been found on birch leaves in Finland. Scl. alni Naw. Woronin found this first on catkins of Alnus incana. Nawaschin has more recently investigated it.^ Scl. rhododendri Fischer.^ This was first discovered by Fischer in 1891 in fruits of the Alpine-rose (Rhododendron ferrugineum and B. hirsutum) in Switzerland. It has since been observed in various parts of Switzerland and the Tyrol. 1 Nawaschin, Berichte d. devisch. hotan. Oes., 1894; Maul, ffedioigia, 1894, p. 213. With two plates. ^E.
