the Califorina funnel chants, and they seem to be quite macro-variable. I see that Noah has used the name “neotubaeformis” for some of his CA observations.

Like you say, Walt, tubaeformis is more common than ignicolor here in eastern PA. And the fruitings of tubaeformis are generally much more substantial… sometimes 50-100 mushrooms in just a few square yards. When I find ignicolor, it’s usually just 2 or 3 mushrooms.

Bessette and Fischer described the fibrils as erect fibrous scales. On the other hand they separate C. tubaeformis (with scales) and C. infundibuliformis (without scales) I don’t know what that means if they are one and the same.
Craterellus ignicolor as I know it, is closer in color on all parts and is never as dark on the cap as C.tubaeformis which usually shows more contrast between cap and underside. In my experience in Pa., it is more common than C. ignicolor. As I mentioned in an earlier post, all bets are off when looking at California C. tubaeformis which I think is being renamed.

Thanks Walt.

The ignicolor on the Quebec site show a wider range of color than I would have supposed for this species. Are the minute marginal fibrils a feature one may use to distinguish oddly colored ignicolor from tubaeformis?

on C. ignicolor are marginal and require a hand lens. Obs. 71471 looks good for C. tubaeformis. Hymenium color on both species is variable. When I see C. tubaeformis, it is most commonly in bogs or wet conifer forests. C. ignicolor occurs with broadleaf trees and conifers but often in drier forests. Look at the variations of C. ignicolor onthe Quebec site.

Maybe my concept of tubaeformis…

needs to be revised. But I have IDed collections here in PA that show a fairly wide range of color in the fertile surface… whitish, yellowish, grayish, violaceus. I think that back when eastern NA manuals included both tubaeformis and infundibuliformis the supposed distinction was partially based upon color of the fs.

Here’s a post of tubaeformis for which the caps are flaky/scaly. I have also seen this in my collections of tubaeformis.

The photo mimicks a more greyish-violet hymenium.
You’re right.

Cap yellowish orange becoming brownish

Margin has minute brownish fibrils. Eastern North American C.tubaeformis has a brown cap and violaceus hymenium at first. What passes for C.tubaeformis in Western North America looks very different to me.

Isn’t C. ignicolor uniformly yellow to orange-yellow?

Why not C. tubaeformis or your North American brother of it?
