Clitocybe cokeri (Neohygrophorus cokeri)

Hesler collected this species frequently from 1937-1964 (19 collections) but after 1964, no more records of this species (neither under the name C. cokeri or Neohygrophorus cokeri) being collected in the UT herbarium.
From that description in Redhead, Ammirati, Norvell & M.T. Seidl is available in Mycotaxon 76:324, I might want to verify spore size and amyloidicity and confirm some other microscopic characters:
-tramal pigments in the C. cokeri incrusting to intraparietal, yellowish to orangish brown in water, that become immediately salmon to rose tinted in KOH and then fade
-gelatinized pileipellis containeing scattered thin orangish refractive hyphae with contents that do fade in KOH.

The description does explain that N. cokeri is distinguished from N. angelesianus “by size and odor/taste (noting that C. cokeri produced larger basidiomes characterized by a farinaceous odor and taste) as well as by their
disjunct distribution (Ciirocybe cokeri appears to be restricted to Tennessee in
the Great Smoky Mountains and near Knoxville whereas N. angelesianus (as C.
mutabilis) is a western montane species.”

The citation for the Clitocybe cokeri (Hesler) is Smith & Hesler, Lloydia 6: 25 1. 1943 which is not available from Cyberliber but I may be able to access this, and if it waranted that level of investigation, could look at C. cokeri material in the herbarium as well.

The description of this species (N. cokeri) to have a destinctive odor, have a southeastern distribution, and fruit during winter months (December and January)would make this a very promising ID.

It was first described as Clitocybe cokeri by Hesler & Smith (can’t find that one), but Neohygrophorus cokeri (Hesler) Redhead, Ammirati, Norvell & M.T. Seidl is available in Mycotaxon 76:324.

You can find it here: http://www.cybertruffle.org.uk/cyberliber/
choose Journals, then Mycotaxon, finally volume 76, page 324

Irene, do you have a link or copy of this description? The smell was very distinctive! That it is known from TN makes that sounds like a very promising ID!

Good observation

There is another species described, Neohygrophorus cokeri (Clitocybe cokeri).
It is said to differ from angelesianus only by its larger size and different smell – and being known from Tennessee :-)

Seems to occur under Redwoods on the west coast. These were under hardwoods and some Juniperus virginiana and would be a first record of this species on the east coast other than my other observation: http://mushroomobserver.org/88206?q=u7cp
which was also found under hardwoods. l Also other observations of the species show a single small specimen, maybe two, while these were rather large (cap of the largest one 5.5 cm) and there were quite a few of them. I think I need to carefully recheck for amyloidicity in case the micro graphs are misleading.

thank you.
wish that link still worked…
sounds awesome.

I only browsed through the key to genera in Funga Nordica, but we don’t have Neohygrophorus – so I had to look up a description to that one.
I used to have a link to “Spores of the gilled fungi” where different characters were listed, but it has disappeared..

They look to me to be

pretty obviously amyloid, but its difficult to see any detail or spore morphology. I will update with some better images when I get into the lab on Monday.

thanks irene…

may i ask where you are getting this information?
just for future reference…

in Neohygrophorus, Pseudoclitocybe and a few others – not in Lepista
