zones. The milk is white, soon changing to greenish yellow, and is 
not strongly acrid. The pittied stipe and coarse hairs are well shown 
by Krombh., Schwam. PI. 58, fig's. 1-6. Specimens found in ope'n 
places are nearly white, those in deep woods are yellowish. Schmeil- 
ing’s woods, August, Algoma. 
Lactarius subdulcis Fr. Cooke, Illust., PI. 1002, figures the forms 
which grow abundantly in Riverside swamp, October, Algoma. 
Lactarius torminosus Schaeff. Fresh plants are nearly white; 
the reddish zones of the pileus are seen only when the flesh is broken 
or the plants are dry. Rolland, Atlas Champ., PI. 33, fig. 63, illustrates 
characteristic specimens. Frequently found to be parasitized by Hy~ 
pomyces. Common in Blahnik’s woods, September, Algoma. 
Lactarius trivialis Fr. The quantity of milk in the species is 
variable. During dry weather large specimens growing in sandy soil 
contained only slight amounts. Mile bluff, June, Mauston. 
Lactarius vellereus Fr. This species grows in dense clusters in 
old roads. Most plants have a stipe only 4-5 cm. long, with pileus 10- 
14 cm. broad. Boudier, leones Mycol., PI. 49, no. J7, figures such forms, 
except that there are no red spots on the gills and the pileus is more 
tomentose. Blahnik’s woods, August, Algoma. 
Lactarius volemus Fr. On the ground in wet places, Krohn’s 
lake and Blahnik’s woods, September, Algoma. 
Lactarius zonarius (Bull.) Fr. Specimens of this species grow to 
be 20 cm. across and when dry show 5-15 distinct zones, which in 
fresh plants are watery rings in the flesh. The milk is white, slightly 
acrid, with no change of color. The spores are white. The flesh is 
firm and free from larvae. Quantities were cooked and found tough 
and of a strong flavor but not poisonous. There is just such a ten¬ 
dency for the plants to grow in pairs as is figured by Bulliard, Herb.
