is not going as well as I thought it would. I’ll post something if I get a good result. Macowanites isn’t just related to Russula, it’s polyphyletic and its species are nested in Russula/Lactarius. I’m calling this Macowanites since it’s a sequestrate Russula that resembles named species that have been assigned to Macowania and since AFAIK that whole taxonomic mess hasn’t been sorted out yet. It could also be Elasmomyces, which is also just a sequestrate Russula and has been considered synonymous with Macowanites (according to Wikipedia at least). Here’s a relevant paper: http://www.mykoweb.com/...

I’m gonna be going to sleep soon but I’ll look over it tomorrow.

Macowanites, I come across several references to collections from Teresa Label and Michael Castellano from Australia. May be much more widespread.

Definately need more photos to compare with known collections.

of herbarium material would still be good, Django.

Macowanites are related to Russulas. The smell further helps that analysis. The Quercus palustris and Carya ovata further restricts the possibilities.

Thanks for adding that information on your notes.

have any more closeups. I could scan my herbarium specimens of this and I could even cut one of those if that would be helpful, but I don’t have any photos of these that I didn’t already post. I had more pictures of 141054. They weren’t very good and probably wouldn’t have been all that helpful, but I lost all of them when my portable hard drive broke 2 years ago. One important detail that I forgot to mention is that the stems had a Russula-like texture. The oaks were pin oak (Quercus palustris), and pin oak leaves are visible in this picture, and the hickories were shagbark hickory (Carya ovata).

may be Macowanites. May also be another sequestrate fungi. Need more close-ups of cut sporocarp. Need detailed description of possible host trees. Which oak and hickory species? Odor suggestive of Macowanites, but reserve until better photos provided. Seems to have larger locules present than normal of many species of Macowanites. But in my area, Macowanites is usually associated with conifers instead of hardwoods.

here (http://mushroomobserver.org/141054?q=2ZPuH) and this one here (http://mushroomobserver.org/176987?q=2ZPuH). This is from the same patch. I posted this one so that I would have an observation # for this specimen in my herbarium. I could post a picture of the dried specimen itself if necessary.
