One character that might be useful in the field is that there are very few short gills on the cap and these are mostly a little less than half the length of a full-length gill. There are no very short short gills as are often seen in amanitas. The material dried with the gills nicely and distinctly separated so that the short gills can be clearly seen.

Also the gills are distinctly marginate. They may have had an orange margin originally; however, in the dried material, the gills’ margins have become dark brown.

Very best,


Thanks Ron,
