GYMONSPORANGIUM sp. No. 1079, on twigs of Juniperus 

 monosperma, at Mancos, July 8, seems to be an undescribed 

 species of this genus, but our specimens are all old and 

 sterile. They form globular swellings an inch or more in 

 diameter. Spots of an undeveloped Rcestelia were found 

 near this, on leaves of Amelanchier. 



GYMNOSPORANGIUM, sp. No. 1078, on twigs and branches 

 of Juniperus nana, Bob Creek, 11,000 feet, July 5. This 

 causes fusiform swellings of the limbs much like those 

 formed by G. clavipes, but the spore-masses are different in 

 shape and of a lighter color, and the spores lack the swollen 

 pedicel characteristic of that species. It is probably new, 

 but our specimens are not in a condition to insure correct 

 diagnosis.
