In the case of S. cinctus,

A significant range extension by finding it in BO? Maybe, but all reports I know of have been Neotropical, as in Brazil, the type locality in Surinam, and whatever others I’m missing. The S. cinctus habitat, however, always appears to be some degree of lowland tropical rainforest. The difference here with Ameghiniella isn’t so much a matter of range, but the contrast between high elevation Patagonian Nothofagus forest and practically sea level Bolivian Amazon. If it is Ameghiniella, there is this obvious habitat discrepancy to grapple with, a theory worth pursuing about tannin levels of possible “surrogates” for Nothofagus, and some microscopy that has to happen before I, personally, would make such a leap of faith. Odor and consistency in discomycetes don’t rank among the most diagnostic of characters either…

I have found Ameghiniella australis a number of times in Patagonia, it is true. Substrate was usually assumed to be Nothofagus, as that is the dominant tree genus. This material was identical in morphology and texture, and was odorless, like previous collections. It is not too much of a stretch for me to see this growing on a high tannin wood of some tropical species, as the Coihue tree and the Roble are so named because of their high tannin concentrations, making them slow to decompose. This is a pretty common fungus further south, I would not be shocked to see it up this far north. Finding the Staheliomyces in Bolivia was about that much away from its previously reported range..

I see A. australis is listed

in Gamundi and Horak’s Fungi of the Andean-Patagonian Forests, and is described as occurring on Nothofagus all year round. Spores 4-6 × 1-1.5µ, cylindric to allantoid, hyaline, smooth, embedded in a slimy sheath. Also stains purple in KOH.

I suspect this was sight IDed in the field or likened to the entry in the Andean-Patagonian Forests book. Unless there are other Ameghiniella substrates in Madidi, and microscopic confirmation to go with this proposal, it seems like a bit of a long shot, don’t you think? After all, the book is meant to cover southern Chile and Argentina.

edit: I’d recommend upping this to AscoFrance, though without micro, it’s really a toss up.

I remember this… someone wrote down the common name as something like “[sometihng] rose,” “black rose,” on the collection box. How did you ever come across this taxon anyway?

Greatly looking forward to more of your Amazon Mushroaming finds from 2012.
