Collection location: southern Tierra del Fuego, Tierra del Fuego, Argentina [Click for map]

Specimen available

These are all probably the same as observation 18449, but I wanted to record the variation in color. These, too, were VERY ACRID. Oh, and you can clearly see the white spore print on one of the caps in the second photo. Definitely not creamy or yellowish or anything else — pure white.

Note that I was deliberately showing the extremes in variation here

Reading between the lines in my notes, I suspect this was really common. It’s probably not surprising to find at least one collection that breaks the rules, right? I was going out of my way to find it, as it were.

good points

what’s more, Fungi of the Andean-Patagonian Forests only lists one other Russula, R. fuegiana, which is whitish. There is one point of contention, however, and from the same source:

“…the pink-purple tinge on the stipe is never lost and hence R. nothofaginea can be immediately separated from related species also occurring in the area."

At least one of these stipes appears to lack that coloration.

Mixed collection… but maybe not multiple species

It’s hard for us northerners to really “get” just how non-diverse southern Patagonian forests are. We’re talking one species of tree over vast acres. It would be surprising if that doesn’t correspond to relatively low diversity in mycorhizal fungi, too, right? It does in lichens. For example, in North America, by far the greatest diversity in epiphytic macrolichens occurs in Great Smoky Mountains National Park (by a large margin); those mountains also have the largest diversity in species of trees (by a similarly large margin). There are other factors, too, of course, and it could just be coincidence, but I think not.

by Jason’s admission. i’ll give it a ‘Could Be.’

it is mixed… There’s really not many Russula down there, and we all know how much their cap color varies within species and even individual mycelia.

Yes this is a mixed collection, from three groups spread over about 1/4 acre. However, the mixture isn’t as you’d expect: one group had the full range of colors. I don’t remember which wound up in which photos, sorry.

Mixed collection?

Then again it is a Russula…
