That cladogram is bad news

for more than just Hygrophorus lovers. From the second image on that page, it looks like the big, well-known genus Clitocybe isn’t remotely coherent! It’ll get split into a dozen little genera.

On the other hand, I can’t say I’m surprised to see Psilocybe split up (bluing vs. non-bluing clade, presumably) or to see it close to Stropharia, and Stropharia, Hypholoma, and Pholiota (and Kuehneromyces) close together.

Interesting that the big Cortinariaceae genera — Inocybe, Galerina, Conocybe, and Cortinarius — are somewhat separated, and that Lepiota is much closer to Agaricus than to Amanita.

Curious that while some of the toxins are confined to a small part of the cladogram (e.g. orellanine only in Cortinarius, which seems to be coherent), amanitin is found in scattered, widely dispersed parts of it (Amanita in the top image, Galerina, Lepiota, and Pholiotina in the bottom).

Even curiouser, there are indications in there that well-developed mushrooms sometimes evolve into clublike clavarioid forms, and lignicolous mushrooms sometimes progress through loss of their stipe to loss of their entire structure, becoming crustlike fertile surfaces, as in Chondrostereum, which the cladogram tucks in among several agarics.

Sorry, missed the details on the hike for this set of mushrooms. Can’t determine their smell tonight either as they went to the science fair this afternoon!

May go back and pick up a few more and get better information on them.

Will review my collection notes and get back to you

Picked these yesterday. They have remained outside and still seem fresh so hope to check smell when I get home from work.

the Hygrophoraceae should probably be divided, at least into Camarophyllus (pratensis, virginea and its varieties), Hygrocybe (sensu stricto) and Hygrophorus (mycorrhizal), since Ampulloclitocybe clavipes, Chrysomphalina and a few other odd groups are stuck in between in the cladogram.


Yeah, probably…

I saw this and thought Camarophyllus virgineus, with the thicker stipe and the pink base. Is there a reason for the preference of Hygrocybe over Camarophyllus? (Or even Hygrophorus?)

Was there any odor associated with these? I also thought he should keep in might Clitocybe fragrans. And with the intervenose lamellae there is also Marasmius calhouniae, except here the stipe seems a little thick for that.

Are there any notes here on the habitat?
