Hello Byrain

I’m only posting what I find in my references that are supposedly found in my area. Since I’m not from California or Europe I’m not familiar with any species which are prevalent in those areas. Heck, besides Pa. the only other state I picked mushrooms in was in New York on my son’s property; but thanks for the heads up.

There are at least 4 or 5 species going under this name in CA alone, what makes you think its different elsewhere? Even in Europe there are multiple species.

They are

only “uncommon” when they are not found by one or two people in a given ecosystem. You are correct in assuming conocybe filaris as a synonym as evidenced in the taxonomic description being deprecated.

Thanks Byrain.

Looks like “promising” is as good as it gets for calling this P. rugosa. As far as I can tell, these small ringed pholiotinas are uncommon around here.

My reason for maintaining my “promising” vote for “Conocybe rugosa” is because I think it’s a good idea to allow synonyms to stand along with a moderate level of confidence. This way, someone who is using the depreciated name is more likely to grasp that the mushroom is possibly what they think it is… except that the name has changed. To that end, another older name for P. rugosa is (I believe) “Conocybe filaris.”

According to mycobank and index fungorum, Pholiotina rugosa is the current name. And this is from Flora Agaricina Neerlandica 6 on the subject:

“Following Watling (in Br. Fung. Fl. 3: 92, 95. 1982) several authors
distinguish two species: Pholiotina rugosa sensu stricto with somewhat
stouter basidiocarps with a rugose pileus and larger spores (8.0–10.0 ×
4.5–5.5(6.0) μm) and Ph. filaris with small basidiocarps and small
spores (according to Watling (6.5)7.0–8.5 (9.5) x (4.0)4.5–5.0 μm). In
the studied collections no correlation between spore size and size of
sporocarps was found. Many intermediate collections exist with regard
to the stature of sporocarps and rugosity of the pileus. Therefore, Kits
van Waveren (in Persoonia 6: 156. 1970) is followed in synonymizing
the two species, except for his nomenclature since the name Pholiota
rugosa has priority over Pholiota filaris.”

However, there are other Pholiotina species that look like this such as P. vexans, I’m not sure how to distinguish them macroscopically and FAN6 says you need to rely on microscopy…

I did a little checking…

but I’m still wondering… Is Pholiotina rugosa the currently preferred synonym?
