Observation 72835: Cuphophyllus angustifolius (Murrill) Bon

When: 2011-07-25

Collection location: Moon Lake Park, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

I have found this type of mushroom in the exact same location during several different years… low lying drainage/runnoff area in mixed hardwood forest. The color is invariably chalky white with a hint of peach on the cap. Reminds me of C. pratensis, only without the expected colors.

If it’s a different species

and not just a less pigmented form of pratensis, Hygrocybe berkeleyi is also a possible valid name.

Regardless of your genus preferences. Hygrocybe pratensis var. pallida (Cooke) Arnolds I think is a valid name and like Hygrocybe pratensis var. pratensis (Persoon : Fries) Murrill it is usually robust but not always.(and there is a variety robusta!)

As for H. borealis and its forms I think they are synonymous with H. virgineus.
Other than provisionally form Salmonea has not been published. Hygrocybe virginea f. salmonea (Coker) comb.nov., was originally described under the name Hygrophorus borealis f. salmoneus.

To reiterate…

the real fun comes into play with the species names.

Based only upon what I have gathered from field guides and internet sources, I have come to think of the borealis/nivea/virginea types as being rather thin fleshed. I think of pratensis as a more robust solid fleshed mushroom, at least with young specimens.

However, the following quote from Kuo’s website provides a much different concept for borealis. “Hesler & Smith’s own concept of Hygrophorus borealis appears to represent a different mushroom—one with a non-gelatinized pileipellis and much stockier proportions.”

So is the name “pratensis var. pallida” a valid species name? If so, how does one distinguish it from borealis f. salmoneus?

I’ve read a few of the Hyg/Cam discussions.

Personally, I like “Hygrocybe” because it’s easier for me to remember how to say it :-). Seriously, the whole name thing seems a lot easier if the genera are lumped. But species names… now that’s where all the fun happens! Like the one seen here, macroscopically very similar to H. pratensis, except virtually completely white. I’ve found this type during three different years, always in the exact same spot, in a shallow washdown gully in a hardwood forest… oaks, ash, hickory. Thought for a short while that I had found a White Chanterelle the first time I found a few.

But it is a bit perplexing to me that the genus has been changed from Hygrophorus to Hygrocybe. Most of what I understand to be Hygrocybes seem to be fragile and insubstantial, often with watery flesh. The pratensis types are quite robust, and thick-fleshed. I guess the choice is based upon some micro characters…. which presumably takes us back to the “genus splitting” question…

Looks like I may have learned a new one today.

If I find another batch, I’ll fry them up and see what they taste like.

Nice find

Good software design by these guys.
