Report of the Botanist. 109 



Agaricus campestris v. villaticus Brand. 



This large and well marked variety was found as early as June 

 in rich soil near Albany. 



Lactarius uyidus Ft. 



This plant usually grows in swamps, but fine specimens were 

 found growing on dry soil under pine trees at Center. 



RussuLA Mari^ Ph. 



Near Albany. The spores are yellow. 



POLTPORUS ELEGANS Fr. 



Speciiuens were found in the Adirondack woods with the stem 

 entirely black, and in some instances with a black spot on the 

 pileus opposite the insertion of the stem. 



Uredo Pyrol^ Grev. 



There are three distinct varieties of this species. The first, 

 which is tlie most common, is without spot, the sori are numerous, 

 equal, rotnud and occupy the whole under surface of leaves of 

 Pyrola rotundifolia / the second has a brownish spot and the 

 small rotund sori are distantly scattered over the under surface of 

 leaves of P. secunda j the third has the sori large, irregular 

 and confluent, long covered by the epidermis and occupying the 

 lower surface of leaves of P. secunda. It sometimes succeeds the 

 second variety on the same leaf. 



.^CIDIUM HOUSTONIATUM Schw. 



Slope of Mt. Marcy on Houstonia ccBrulea. 



^CIDIUM TENUE SgJiW. 



Sandlake in September. It usually occurs in July. In the 

 present instance the plants on which the JEcidium was found had 

 been eaten at the top by cattle. New branches had grown out 

 beneath the injured part and on the leaves of these the parasite 

 occurred. The inference is, that the age of the leaf has some 

 influence in determining the time of the appearance of the parasite. 



PiLEOLARIA BREYIPES B. (& R. 



The spores are vertically flattened when dry, but under the 

 influence of moisture they soon become globose. The specific 

 name seems quite inappropriate unless it be a comparative one, for 

 the peduncles are several times longer than the spores. 



TORULA POPULTNA Ph. 



This is not a good Torula and must be referred to the genus 

 Myxormia.
