Thank you Erlon-

Makes me rethink what I post and how I view certain fungi and fruiting time of year. I appreciate your input and hypothesis based on the volval remnants looking like A.aprica. Made me wonder- I have found species that overlap seasons(Pseudohydnum gelatinosum, various boletaceae, Amanita spp., Russula spp., Galerina spa. and countless others) so it never hurts to look at all species(even if seemingly obvious or commonplace) with a critical eye.

Thanks again,



I agree

However, A. aprica is also yellow in the upper part of the cap flesh. the removable warts points away from A. aprica however. In the pic they looked as though they may have been adhering. Thanks for clarifying and nice find!


You’re welcome, Drew.

With the volval remnants flocking from cap(not adhering to, and stretching with the pellicle like A.aprica). Also, Season is not quite right for A.aprica either. I usually see the A.aprica, along with the A.pantherina group start appearing around April/May. This was just one of many A.muscaria subs. flavivolvata found this week in this location.

BTW- I have the fruit body here at my home if Rod or any others are interested( along with A.augusta and A. Pantherina collected from this summer).

Thanks again Rod :)

The reported yellow beneath the red cap skin…

is the color found in a thin region of the cap’s flesh. The yellow pigment quickly lessens in concentration as the distance from the cap skin increases. This is completely typical of muscaria subsp. flavivolvata.

Very best,
