Excerpt from Endothia Parasitica and Related Species: January 15, 1917

Ivhen there were included in the original packet specimens from different hosts or different localities, in some cases representing dif ferent species, it would have been difficult, if not impossible, to de termine which was the original material from which Schweinitz's description was made. At the Same time, Dr. Michener, in case the specimen was not too scanty, evidently took a small portion of it for his own herbarium. Michener's catalogue of his herbarium lists Sphaem'a gyrosa Schw. Consulting his collection it is found that N o. 1431, the number of Schweinitz's specimen, is missing. Pin holes in the mounting sheet, however, Show that the specimen which was once there has been removed. As perhaps throwing some light on the possible location of this specimen, it may be said that a speci men apparently typical S. Gyrosa, pycnidial form on beech, labeled by Dr. William Trelease as S pfiaemlw gyrosa from Pennsylvania, was seen in the Boissier' Herbarium, Geneva. Dr. Trelease tells the writers that this specimen probably came from Dr. Michener, and as there is no evidence that Dr. Michener or any one else has col lected E. Gyrosa in Pennsylvania there is considerable probabilitv that this specimen represents a portion of Schweinitz's original col lection.
