Much appreciated. I agree with your suggestion for appropriate mycorrhyzal tree host being most important factor. I also looked at some other observations, particularly by Michael Beug regarding the initial taxonomy and post for C. cascadensis near the Columbia, WA. That area of the state is much less montane and obviously is hospitable for cascadensis. Now I know :)

Thanks again!

Fungally,

Drew

While I wouldn’t say I am 100% sure, I think the extreme white hymenium and more clear yellow color (rather than a an orangey-yellow or pinkish-yellow color) of the cap, as well as the stout stature point to C. cascadensis. I have never tried to use the texture of the cap as an ID character between these species, so I can’t speak to its reliability.

See this observation 151991 for a nice comparison.

As for the elevation, I am not sure what the known range is. However, it’s a general pattern that lower elevations at higher latitudes are more similar to higher elevations at lower latitudes. I think C. cascadensis is known from fairly low elevations however – see observation 4610 (there are others on MO as well).

I think the more important factor would be the presence of an appropriate mycorrhizal host.

Are these still C. Cascadensis. If they are friuiting at sea level? Not even near foothills? Just curious because I’ve only encountered this species above 2000ft. Let me know- I encounter 100s of chanterelles a season here in WA state and want to nail them down. Although these DID have vibrant white hymenium and a vibrant yellow cap, THEY LACK velvety, minutely hirsute margin with white ridges and canary center in caps especially with young specimens.. To my knowledge these factors(in addition to elevation conflict) would rule out C. Cascadensis.

I would love to know more info you have on C. Cascadensis and how it differs(other than afforementioned characteristics I listed) from C. Formosus.

Thanks again for all your help-

Fungally,

Drew
