young fruit body with pale gills.
heavily spiculose cap.
gills turn up and yellow with age.
apologies for poor photo quality.
note dark center of cap, pale edge.
note metuloid, an encrusted, thick-walled cystidium in upper middle portion of lower right quadrant.
dark-headed metuloid in lower right quadrant.
last metuloid, same area.
1000 x, congo red.

Recognized by sight: small (1 cm) sessile fruit body, pale spores, dark, heavily spiculose cap with a pale edge.
cream colored gills turned up and yellow in maturity.
30% (2)
Recognized by sight: I agree to the genus, but the sp. is not quite fitting. Doesn’t look a thing like the mushrooms depicted in Mycoweb: gills here thinner and more crowded, cap much more spiculose. I’ll look at some of the micro features today.

haven’t seen the smaller cystidia with finger-like projections yet…

Looking forward to see a micro shot

Hohenbuehelia species are nice to watch in the microscope :-)

made a more comprehensive work with Hohenbuehelia than anyone else has, I think.
Look up Mycotaxon 25, there’s the study on pages 321 to 453. An interesting detail there is that 4 of the species share the same anamorph (atrocoerulea var. grisea, nigra, approximans and cyphelliformis), one way of proposing that they actually are the same species..
I don’t remember exactly where, but have I read somewhere (maybe it was in Thorn & Barrons paper) that Peck had agreed that his grisea was the same as atrocoerulea, but still wanted to keep grisea as a brownish colour form, because he hadn’t seen them blue as atrocoerulea was described.

I don’t think any complete DNA studies on this genus have been made yet, so the choice to separate the species in Funga Nordica is probably not based on any new research, just a copy from Flora Agaricina Neerlandica.

I did.

I await the description from Funga Nordica.

Compared with multiple sources…

I compared what I saw with Mykoweb, and Michael Kuo’s Mushroom Expert. And went through the key and descriptions in Funga Nordica. Then looked at the cystidia and spores under the scope.

If you agree that we have the same species, well then you either agree with my id, or not I guess…

Just look at the description in Mykoweb and Mushroom Expert. Are you getting hung up on the photo?

I agree that we have seen the same mushroom, Doug.

My confusion lies in the fact that two very different looking mushrooms are sharing the same name.

where is the original description for this species? It would be useful to compare my material with that.

May just be examples of variability within species, but I’d still like to see
some broader data to compare with.

Don’t look at the Mykoweb photos…

Well, look at the Mykoweb photos, but also look at my photos from last month:

thanks Doug.

Hohenbuehelia did spring to mind…altho at first I thought Crepidotus due to the sessile form…but even those mature fruit bodies still showed light colored gills, so no Crepidotus here.
