Here’s yet another enigma with these.

To prepare for eating/freezing, I always par-boil collections. Some of the boiled Armillarias have gills that turn dark brown. Others have gills that remain whitish. This is not continuous color variation. The boiled gills are either whitish or dark brown. This happened with the ones represented in the three obses I just posted, and I think they’re all the same species.

Sometime this spring I stopped enjoying foraged mushrooms. Once you’ve seen so many nematodes under the microscope… Blech.

I have never had a collection of A. mellea stain pink or have a ton of yellow uv remnants. Usually the stipe has white scales and rarely there is some yellow as a result of pileus inclusion, but not fully clothed in yellow. The literature on mellea is vague about these characteristics, so I just assumed mellea doesn’t do that. Last night I pulled up a batch of east coast mellea obsies and practically all of them stain pink and have a ton of yellow fibrils. So aggravating. Is the east coast mellea an intermediate variety or species? Does the pigment of the universal veil or rubesence depend on local ecological or environmental factors? Paugh!

Yeah, plenty of ambiguities.

Check out a couple other Armillaria posts I just made, yellow deposits on the PV which tends toward cortinate. obs 179486

But I don’t despise these. They are all quite tasty. Most popular edible wild mushroom in my locality.

Armillaria, lol.

The pileus shape and annulus indicate mellea but the stipe bases are not fusiform. I think I despise this genus.
