CLASSIFICATION OF AGARICS 7 



undeveloped under the pileus. The margin of tin- pileus rests on the 

 broad bulb and produces the typical, abruptly depressed edge of 

 ili;ii body. The cortina extends from the margin of the pileus to 

 the bulb, to whose upper Burface it is attached and, during develop 

 ment, is carried up on tin- lower part of the elongating Bteui. The 

 universal \ t-i 1 when presenl envelops the I »i 1 1 1 • and extends to the 

 Burface of the pileus in the form of a thin, Blightly woven mem- 

 brane, which breaks away in ;i circumscissile manner from the mar- 

 gin of the pileus a1 an early stage and is only noticeable, after the 

 expansion <>r the plant, on the exterior of the bulb or where the torn 

 fringes of its upper portion extend above the margin of the bulb and 

 lie againsl the stem; il is usually of the same color as the Burface 

 of ilic pileus and this shows on the bulb and on the stem immediately 

 above it. Sometimes this veil is slightly gelatinous. Species occur 

 which are intermediate between this and the following subgenus, 

 where the bulb is scarcely depressed or marginate, or where the mar- 

 gin of the pileus almost covers the slight bulb so that the latter is 

 margined only about its base. The stem is never peronate nor an- 

 nulate by the universal veil in this subgenus. The connection of 

 the margin of the bulb with the cap and the circumscissile manner 

 in which the universal veil breaks across are somewhat similar to 

 the COndil ions in some Amanitas. 



The species of this group are numerous, and many more will prob 

 ably be found in Michigan. Pries appears to apologize for including 

 ami naming ao many species under the section Scauri, as witness his 

 remarks under that section in Epicrisis: "An astonishing num- 

 ber of closely related forms, which, although they were all constant, 

 I was ashamed to separate in Sys. .Myc. but published them under 

 titles which were much broader. Bui I am compelled to recognize 

 them lest the limits appear to be arbitrary, since their existence 



in nature has Keen verified many times." Nbl a lew others have 



already been found in the State, but their identity is nol yel estab 

 lished.
