Notes on Taxonomy: [Edit]

In the western US, there may well be a couple of species hiding under this one name.

There are some pretty common color variations like in this observation. There also seems to be some common size extremes.

In addition, a few years back I found a Hygrophoropsis with a spermatic odor. I’ve done a little informal checking since then and is seems like the smaller brighter ones are more likely to have this features and the larger and browner ones don’t. I’d be interested in getting more data on this. I’ll also add a comment to the name page.

The only other Hygrophoropsis that I find commonly referred to is H. morganii (= H. olida) which has a distinctive sweet odor. Fungi of Switzerland, Vol. 3 has photos of both H. aurantiaca and H. morganii.

PS See a phylogenetic ITS tree here: https://mushroomobserver.org/284484?q=1UZwa indicating that there are a half dozen or so undescribed taxa in the H. aurantiaca group including several in western North America and several in eastern North America. The taxon was described from the UK.

Geoff:

One way to get classification information for an MO Name or Observation is to follow the Mycobank link.
(That link lands you on the result of a Mycobank search for the binomial. If there’s only one hit, scroll down to Classification. If there are multiple hits, click on one, then scroll to Classification.)
(I’ve now added the information to MO for this taxon.)
