that may well be…

but no way to prove it now. if not blue, tho, why NOT xanthodryophilus? Cap too pale?

I did not travel with chemicals nor slides, so collection and analysis of most fungi and especially corts that I encountered was not possible. I did actually have access to a dryer, though, and dried some of the more interesting species; alas, this cort did not make the cut.

Something more interesting…

Debbie your excellent collection from San Diego is something more interesting than C. xanthodryophilus. If you insist that there were no bluish tints then I also cannot say what it is other than a Phlegmacium in the big calochroid clade. Some KOH and spores would have helped, but I understand the challenged of collecting in San Diego.

If you do not have a drier then getting a few pieces of the lamellae and putting them on the glass slides helps – they dry there very fast and present excellent opportunity to check the spores and run DNA. Keep that in mind!! One cannot use such material as a type collection naturally, but one can know a lot better what was at stake. And even better, you can put on that slide a thin slice of the pileipellis too, so that we can analyze that part too.

Very good collection – these phlegms are real pretty… particularly from the southern oak forests.


what this is, is still a matter of conjecture…

and I didn’t save the fruit body, but it surely did NOT have violet tones on it. That is merely an artifact of the light and shadow.

Dimitar says not C. xanthodryophilus

Because there is purple on the stem. I can’t see it on my monitor though.

He says this species is unnamed, but closer to C. calochrous.

Thanks for these obses from San Diego, Deb.
