Excerpt from Orange Rust of Raspberry and Blackberry, And, a New Factor in Economic Agriculture
The appearance of the mycelium depends somewhat on its age. When young it is more conspicuous, but when old it loses its proto plasm and acquires an occasional septum. The haustoria are at first simple threads extending half way or more across the cell. They soon begin, by coiling or wisting, to form an enlarged, knotted end. This possibly may be due to the effort of the haustorium to come into more intimate contact with its food particles. Sometimes two haustoria are found in the same cell, and not infrequently have there been seen signs of union of these (plate 3, fig. 3, 4, This, however, is to be interpreted as nothing more than an accidental occurrence.

Excerpt from Orange Rust of Raspberry and Blackberry, And, a New Factor in Economic Agriculture
So far as known this fungus has limited its ravages to the genus Rubus. Both cultivated and wild species are freely attacked, and of the former quite a number of varieties have been reported as more or less injured, of which the Kittatinny is perhaps one of the worst affected. In this region the Snyder seems usually to be quite exempt from at tack, although elsewhere reported as more or less infected. In the Appendix is given a list of species so far found to be attacked.
