- 48-
Gregarious in coniferous woods. September-October.
Fyn: Bøllevænge near Nyborg (Pieea). - Lolland: Fuglsang
Storskov (Pice a) ; Flintinge Byskov (Pieea).
Characteristics of this species growing in spruce woods are the
umbonate pileus, t he tall stem swollen at the base, the simple,
narrow ring, and t he disagreeable smell which it has in common
with P. decorata. By its unpleasant smell, late occurrence, and dif­
ferent habit it may be distinguished from P. aestivaZis which also
grows in Pice a woods.
