How nice to see you here on MO!

The volva ‘sock’ is too high to be anything but M. volvatus

Danny is correct that there are three related, white Marasmiellus spp. with a volva. The ‘sock’ of the volva extends furthest up the stalk in M. volvatus, as in the specimens photographed in this record, while it is short in M. coilobasis. I’m looking at a photo of a species that differs from both M. volvatus and M. coilobasis (unfortunately, no specimens) that was taken in the southern Bahamas – close to Cuba – so I’m guessing it is M. cubensis by process of elimination. The volva is a shallow, open cup with an upturned rim about a mm from the stipe. The pileus is translucent, and the lamellae are intervenose.

indeed, presence/absence of gill intervenosity looks like a key character in telling as many as three volvate Marasmiellus spp. apart from one another. They are M. cubensis, M. coilobasis and M. volvatus. follow the madness over at Observation 158453!

Marasmiellus volvatus..?

Es un hongo comun en Panama en esta epoca, crece en ramas secas y lianas muertas, tiene una volva estrecha y pegada al tallo.

#1. i am not the one who initiated, the “game.”
#2. do i think there are plenty of mushroom species that “can possibly” look like this…yes.
#3. please, don’t tell me what to do or how to vote…

Please do not play the votes like the game, do you seriously think this is doubtful? If so, please describe what is doubtful about it, thanks. As far as I can tell its at the very least a good match with the concept Danny laid forth.

ok…

maybe, since we can’t even see the gill attachment…
you can convince Eduardo to send you a specimen for sequencing…??

i know a fungus

which has a Neotropical distribution, is lignicolous, white-spored/-gilled/-fleshed, and volvate. its name is Marasmiellus volvatus. it’s the only one I know of with that combination of features, so “I’d Call it That.”

You may call it whatever you like.

i do.
but, you are the first person to reject a name based solely on 1 morphological trait…
what makes this observation any different?
do you not think that there are any other species in the world can share this same attribute…?
or, have you decided…that since YOU proposed the name…you are right?

with these photos…

you’d be a fool, to “call it that.”
