like C. semisanguineus — and of Russula — like R. emetica — were 

 also seen. 



An unusually large cluster of the velvet-stemmed Collybia, 

 Gymnopus velutipes, was observed November 20 on a decaying 

 willow leaning over the Bronx River in North Meadows. This 

 attractive edible species, which persists throughout the winter, was 

 quite common during the autumn on various kinds of dead wood, 

 but it seems to be partial to willow. The cluster in question 

 measured six by eight inches and contained nearly a hundred dis- 

 tinct mushrooms — enough for a considerable meal. It has been 

 suggested by Stewart that this species might easily be cultivated 

 for food. 



A large specimen of Roskovites granulatus, measuring over three 

 inches in breadth, was found recently under white pine trees east 

 of Conservatory Range 1. This rather common, edible species of 

 Boletus grows naturally under pines and other evergreens and 

 seems to be following Boletus luteus in its method of introduction 

 into our grounds. The two species are much alike, but B. luteus 

 has an ample white ring, is much more slimy, and the surface is 

 usually darker. It will be remembered that this species, B. luteus, 

 which is also edible, appeared several years ago under the pines 

 near Conservatory Range 1 and has since spread about the base of 

 individual trees, especially on the northern side, until basketfuls of 

 it may be collected after the autumn rains. 



While doing agricultural extension work in Franklin County, 

 Washington, the writer found a fungus that was unknown to him. 

 Upon returning to the State College the fungus was determined as 

 a species of Battarrea. Further study has shown that the fungus 

 coincides closely with Battarrea laciniata Underwood. This speci- 

 men was collected by the writer June 25, 192 1, three miles west of 

 Pasco, Franklin County, Washington. It was growing under a 

 large sage brush, Artemisia tridentata, in pure silica sand near the 

 banks of the Columbia River. For a description of this species, 

 see Miss White's article on the " Tylostomaceae of North Amer-
