too bad, but even so

this is the only ob. with micro, specimen or none, and I think you stand a very good chance of re-collecting it.

Maybe not because

I am not sure I have a dried collection. I am about to take a road trip across Mexico to Guadalajara, Morelia and Xalapa to pick up all of my dried mushrooms which are stored around the country. This observation is from 2010, which is before I knew it was necessary to use desiccant to store dried mushrooms in Mexico – everything from this era turned to mold. I know a couple places where this species is common, but I haven’t visited them in a couple years.

perhaps this

should be the headquarters for discussion on Rimbachia vs. Rhodoarrehnia as the proper home for these anastomose cyphelloids on account of the attached micrographs.

another of these just collected by Winkler & Evans’ Bolivian Mushroaming outfit, this time all white. hopefully some photos make their way here soon.

I believe these may have been collected by Bryn Dentinger in Ecuador.

see the Rhodoarrhenia name page for Singer’s key.

That which singer redescribes as Rhodoarrhenia cyphelloides was originally circumscribed by C.G. Lloyd as Rimbachia cyphelloides (see ref. in name proposal).

this, in combination with Singer’s key, makes R. cyphelloides seem like a good fit save for a discrepancy in color (dark grey here, all white in Singer and Lloyd). the ‘cystidia none’ is a problem too… unless those cheilocystidia aren’t cheilocystidia.

perhaps Campanella? definitely not Auricularia

Auricularia has basidia that are transversely septate – the picture clearly shows basidia of a different type – that is typically present in Agaricales. So, Auricularia is out.
If the basidiocarps are gelatinous, Campanella might be correct.

VERY cool shroom, Alan.
