Observation 196601: Flammula (Fr.) P. Kumm.

I doubt that this is P. terrestris. The cap shape, color and its complete lack of scales seem wrong even though I know the scales can disappear in age. When I first saw these specimens they struck me as yellow even though the photos don’t show it. I think now that the yellowish smooth cap with red streaks and fibers on the margin may be more telling. The subgenus Flammula may be more appropriate for this obs, if I understand it correctly, according to: http://www.mykoweb.com/... On page 12 of that document it refers to some important macro characteristics: “In Pholiota, the gross features of the basidiocarp—the pileus, flesh (context), lamellae, and stipe—are now as important in taxonomy as they were in the Friesian era. An analysis of the details relative to each structure gives some indication of their use in taxonomy.
Pileus. In our experience, the colors and surface characters of the pileus are highly important in the identification of species. On the other hand, the size, shape, habit of growth, and habitat are of lesser value, and are merely supplemental to those of color and surface features.
In general, the predominant colors of the pileus are in the yellow and brown series. In a relatively few species, there are red tints which modify the browns and yellows.”

I am uploading more photos showing close ups of the cap surface, its red streaks, and its reaction to KOH.

Very dry conditions for weeks.


Red streaks on cap surface and inrolled cap margin
KOH on cap surface—also shows brownish fibers near cap margin. Yellow color of cap more true to actual color of specimens.
