Observation 102719: Cookeina speciosa group
When: 2012-07-25
No herbarium specimen

Notes: Identified with an American field guide, yet this is a Mexican mushroom, meaning that it could be off. The description matches this find quite well however, and hopefully it is common enough to key out in an American book.

I would of never guessed there could be so much variation in just one species. Thank you Danny, that is very valuable information that I’ll keep in mind if I happen upon more Cookeina species. And yes, the two specimens on the top-left of that image match the ones I’ve found like no other, thanks for getting rid of the doubt.

another thing worth noting; color is not the most reliable indicator in Cookeina species:

Many things to consider!

That’s what I was fearing as well Danny, and it looks like it was indeed not worth of trouble of keying out in Arora’s book.

Judging from the images on MO for C. speciosa, it looks somewhat different. The cap seems paler, sometimes not even orange but red, and there is a see-through quality to them — on none of the ones I stumbled on did I immediately consider such a profound characteristic. But all in all, now that I did some serious research on both species, your suggestion is indeed the better candidate, and seeing as you and Danny both have more experience in the field, I’m more confident with that suggestion. Thank you both!

that set it apart from Sowerbyella are the narrow stipe, the hairs on the edge of the cup, the color, and the absence of the mealy-ness so characteristic for Sowerbyella rhenana (look for picture of it!)

your key is not designed for anything outside North America. Mushrooms Demystified is not equipped to treat Mexican fungi. Look around at other observations of Cookeina and you’ll find it’s a most cosmopolitan member of tropical mycota the world over.

Thanks for the input.

Could you mention why you believe that it’s Cookeina speciosa? What are the defining features of that fungus versus the one I’ve keyed out?
