This mushroom WAS identified at the time as hygrophoroides. It was my error, as an Eastern mushroom novice, in calling it a volemus. According to Irene (and other literary sources), macro characters (visible in the photo) are sufficient to separate the species: widely spaced gills, lack of brown staining, no fishy odor (does your computer have the scratch and sniff component, too?). I’ll save the scope work for more obscure IDs…there are plenty!

L. hygrophoroides can be distinguished from L. volemus by its mild smell (fishy smell in L. volemus), not discolouring nor staining latex and not discolouring lamellae and context (latex stains lamellae and context brownish in L. volemus), the distant lamellae, the absence of pleuromacrocystidia (L. volemus has prominent thick walled pleuromacrocystidia) and the spores with an ornamentation of small warts, not forming a complete reticulum as in L. volemus. Thus seeing only the picture, it is hard to say whether it is L. volemus or L. hygrophoroides.

Distant gills

It’s a large difference in the gills. In L. volemus they are much more dense, and they also have a rather quick brown discolouring after bruising. Something I can’t see in the picture is the fishy smell of L. volemus (similar to Russula xerampelina s.l.).

Hi Irene, What are the salient differences between the two species?

Since we ate these, we didn’t run them by Methven (our Eastern Lactarius expert), and members of subsection Lactarius can be awfully similar. How could you tell from the photo?
