Insect galls of Springfield, Massachusetts, and vicinity

Eriophyes avellanae

Hosts: Corylus americana

This gall is an abortion of the terminal bud and sometimes the lateral bud or buds. The stem does not develop, and the leaves become scarcely more than scales. Subspherical, about 1 cm in diameter. On hazelnut, Corylus americana. Rather common. Similar to Phytoptus coryligallarum of Europe.
