This paper gives a summary account of continued experiments on 
the (xmnnosporangia and connected Roefitelice, begun by Dr. Farlow in 
1880. The details of experiments carried on in the Harvard Cryptogamic 
Laboratory last spring by student Roland Thaxter will be given by the 
latter. The cultures of the spores of Gym. bimptatAim on Amelanchier were 
followed by spermogonia and a^cidia of Roe.^. botryapUes. The spores of 
Gym. clavipea (growing on Junipern^ Virginiana), sown on Amelanchier 
and apples, produced on the latter spermogonia and on the former a3cidia 
of Rees, auriantaca. The spores of the form (Gi/m. coin'cam) that grows 
on Junipenis Virginiana, producing the bird's-nest distortions, developed 
on Amelanchier a^cidia of the species Rees, cornuta. In like manner. Gym. 
cUmvriceformis was shown to be coniiected with Roes, lacerata ; Gym. 
macropus is likely (but not positively determined) connected with Rees, 
penicillata ; but the cases of (Hyrn. KlUsii and Gym. globosum did not 
yield to satisfactory conclusions.

The Aecielium Fraxini. Schw., was abundant on the green ash 
[F. cirielis] last year at Lincoln, Neb., also, according to Dr. Ilalsted, at 
Ames, Iowa, but this year, at both places. Dr. Bessey reports it extremely 
scarce. Curiously enough, the fungus at this place (Manhattan, Kans..) 
was eery abundant this year, but rather scarce in 1885.
