in this country, and has passed as Hydnum imbricatum. It has
thick, obtuse, adpressed, permanent scales. The type form of Hydnum
imbricatum (Fig. 758) so abundant in the pine woods of Sweden
and Europe in general, has soft, erect, detersive scales. While Hydnum
imbricatum is common of record in our fungus lists, I have never
seen but one specimen, viz., from James L. Weir, Idaho. The determinations
are based on Hydnum subsquamosum or Hydnum
adpressum.

Hydnum imbric
Fries states, regarding Hydnum imbricatum: "There are two
forms, one with a plane pileus, and thick, permanent scales, the
other subinfundibuliform with free, receding scales." While I do
not know Hydnum adpressum in Europe, I infer that it is the plant
referred to by Fries as the first form. As to Hydnum imbricatum,
all the many European figures I have looked up, and all the specimens
I ever saw from Europe are the type form, which in Europe is
abundant. If Hydnum adpressum occurs there, it must be rare.
