9. Venenarius Frostianus (Peck) 
Agaricus muscariiis minor Peck, Ann. Rep. N. Y. State Cab. 23: 
69. 1872. 
Agaricus Frostianus Peck, Ann. Rep. N. Y. State Mus. 33: 44. 
1880. 
Amanita flavoconia Atk. Jour. Myc. 8: no. 1902. (Type from 
Freeville, New York.) 
Described from New York, and found in woods from New 
Brunswick to Alabama and west to Wisconsin. Among the large 
number of specimens I have collected, very few are at all margi- 
nate or ocreate; in most of them the volva is friable and breaks 
up rather early. In Peck’s first study of the species, he had one 
of these exceptional plants with a marginate bulb and laid more 
stress on this character in his description than later collections 
justified. The species is usually small, but I have found it at 
Lake Placid with the cap 7 cm. broad and the stem 13 cm. long. 
It often shows a fondness for decayed wood as a substratum. In 
collecting one summer at Mountain Lake, Virginia, nearly every 
specimen seen was growing in the remains of old logs, after the 
manner of Russula emetica. 
10. Venenarius flavorubescens (Atk.) 
Amanita flavorubescens Atk. Jour. Myc. 8: iii. 1902. 
Described from Ithaca, New York, and reported also from Con- 
necticut and Pennsylvania. This species appears commonly from 
June to September about New York City, under oaks on lawns or 
in thin woods, and I have had opportunities to study it closely. 
Its various forms have suggested V. muscarius, V. ruhcns, and 
V . russuloides. The color of the cap varies from flavous with 
a melleous tint to dark-brownish-melleous, and both the partial 
and the universal veil are flavous. The remains of the volva 
have usually mostly disappeared at maturity, but at times they 
are quite persistent. The base of the stipe is often somewhat 
enlarged, but is never rounded into a bulb. The characteristic 
tomentum on the stipe is rarely absent and may usually be relied 
upon in determining dried specimens.
