The above-described specieswas already known to the author
from Denmark (Bøtø Nor) when in 1937 Jul. Schaffer sent
him drawings and description of Psalliota campestris v. cupreo­
brunnea Schåff. et Steer, found in Slesvig-Holsten (S t e e r). It is,
however, a good species which, in . a culinary respect too, differs
considerably from white field mushrooms, (no. 7), since it becomes
dark when cooked.
J u 1. S c h a f f e r named the species but die d before he could
get a diagnosis printed.
