There’s not much known about North American Limacella species. I’ve sent a sample of every Limacella that I have to Leiden for two or three genes to be sequenced if DNA can be extracted. That will give us some information that might help sort out distribution of taxa and help us get a grip (anyway a start on a grip) as to how many taxa of the genus there are in North America. I know that I do not have collections that cover the range of morphological difference; nor do I have collections that cover all the places from Limacella species have been reported…much less from all their hidey-holes that no one knows about.
At any rate, without certainty concerning a ring, there is a way to detect members of Limacella sect. Amanitellae. Limacella have (originally) vertical, hair-like hyphae that hold the gluten on the cap in place. In the other two sections of the genus, these gluten-retaining hyphae are roughly of the same diameter over their entire lengths (except for somewhat rounded or subconical tip of the final cells). In sect. Amanitellae one or more of the cells at the tip of many of the gluten retaining hyphae are notably broader than the cells immediately below them on a given hypha.
Moreover, the stems should be dry and not have remains of gluten on them.
So, we have an opportunity to learn something here.
on these messy fb’s. But they’re reminiscent enough of the other fruitings I’ve been finding, that I think it’s fair to call it Promising that they’re all at least in the same section. (3 of the 5 so far have obvious membranous skirts)
I hope we’ll know conclusively when I get around to sending them to you…?
