Hello, Danny.

I am Antonio Ruiz, and I live in Spain. I’m mainly amateur mycologist and study coprinaceae family. Keep in touch.

I’d be delighted. Your English is perfectly functional. It’s the idea that counts (and this is coming from a grammar & punctuation Nazi).

What is your native tongue and country of origin, if you don’t mind my asking?

Danny, if you return to work on fungi Coprinoides Amazon, I’d love to collaborate with you. Next year I’ll start working on a dichotomous key, worldwide.

If you want to work together. Sorry for my bad English language.

Sadly, E-c, almost every last one of these observations, either from Ecuador or Bolivia, is without microscopy, and this has been the bane of their existence. I am planning to return to the Amazon with an arsenal of photographic and microscope equipment, perhaps as soon as this coming winter, during which time I hope to revisit these collections in their respective herbaria and out in the field, as well as documenting as much new material as I can find. The project will be undertaken (primarily) in Madidi National Park in collaboration with the Bolivian National Herbarium. I look forward to taking advantage of your expertise when these observations receive the comprehensive documentation they deserve.

Sorry …

The fungus usually veil this photo, does not seem to be of Coprinus sl I can not tell you something more concrete …

Hi Danny.

I’ll try to help you love it, I love watching the Amazon Coprinus. Of course I know very little flora of South America, and less so little explored area like the Amazon. But at least we can picture the genre right. Do you have full microscopic study of these species?. Not all data is impossible to determine taxon. Now I’m busy, then I see your photos. You study the mycoflora of the Amazon?.
Just some ideas…

Cystoderma? Maybe what appears to be a volval stem base is actually the scaly sheathing seen in members of this genus.

Another similar brainstorm… Leucopholiota?

Thanks! The link should be fixed now.

The previous comment has a link with text “here is a grey, scaly Volvariella” but it goes to a cartoon mushroom image rather than a Volvariella. Either a broken link or a silly joke, and I don’t think the latter was intended.

Well… The scaly, white spored, lignicolous genera that come to mind are Phaeomarasmius and Leucopholiota, though neither come close in shape, nor do the have a smooth stipe, and the lamelle are far more sparse. So that is out of the question… They do remind me of Volvariella as well, and I have seen some finely scaly species, but nothing with such prominent scales.

Here is a grey, minutely scaly Volvariella sp. I found .

Here is a similar species from MushroomExpert .

Another thought was Pluteus, but again, I cannot find any species with pronounced scales, just granular ones.

Something in Coprinopsis is suspect, but I can’t think of anything quite like this.

Nice find!

I thought I had seen this before

of course, last spring! Such a beautiful thing is hard to forget.

just a guess, really. but i believe these could be the same thing.


I agree. Usually I let these things (erroneous but instructive IDs)…

stand for just that reason…but gosh, on further searching, i couldn’t find a single hairy volvariella anywhere! plus, looks like it might have white spores someday. oh well, somebody has to get the ball rolling!

Can’t destroy name once it’s been voted on.

Sorry! The rules aren’t there to make sure you are embarrassed by past mistakes — it’s so that others will be able to learn from the mistake! Besides it sure looked like one to me as well…

Beautiful stuff! I have to get down there!
