Cortinarius bibulus Quél.
Syn: Cortinarius americanus A.H. Smith (1934)
|This "easy to ignore", tiny lilac-brown
Cortinarius is associated with Alnus (Alder) trees. A.H. Smith
described it as Cortinarius americanus in 1934, but later
(1944) synonymized it with the European C. bibulus. Smith does
mention that he had not inspected C. bibulus material first hand, so
I believe that additional regional research is needed in order to
support/reject such synonymy.
