lack of green tones

Thank you for your comment. I (a mushroom dummy) am glad you confirmed my determination since I was puzzled by the lack of green tones too. All other characters (apart of microscopic, which I am unable to check), particularly distinctly slimy caps, tacky upper surface and brown scurfy scales on stems, fitted well to descriptions I’ve found on web. Here are two links to other pictures of P. serotinus from Slovenia, which show considerably more green in caps color.
Warmest regards


I’m glad for this post…

For some reason (maybe its still the joy of being able to identify this mushroom the first time I found it many years ago), I have a special feeling for this species. I remember reading somewhere that it is the harbinger of winter and the end of the mushroom season in the eastern U.S. Thanks for posting these pictures of Slovenian material. I’m used to seeing stronger tones of green on the caps of N. Amer. specimens. Has anyone ever done a careful comparison of the European and North American populations that referred to under this name?
