This is classic Russula dissimulans …

I don’t think that there are scales on the cap. The breaking up of the cap surface in the bigger fruitbody is certainly due to weather conditions. It is also already partly blackened, so must be soemwhat older. In the first picture one sees the cap being smooth. I have not much doubt that it is a “normal” Russula from the Nigricantes group, but am not familiar with the american species

Stipe, gills and red-staining

suggest Russula compacta, but where did those scales on the cap come from? Maybe this is one of the intermediary stages between Russula and Macowanites, but I’ve never seen either species with scales, so my identification is mostly guess. Need to have specimen sliced through the center, after carefully digging out the entire base from the soil, if possible. Gills don’t look crushed or distorted, which probably leaves out Macowanites. Also, specimen seems too large for most Macowanites. But I haven’t found any references to a Russula with a scaled cap either. Cap looks almost like Sarcodon imbricatum, but there are gills instead of spines on the hymenium. I’m stumped, except that it will be in the Agaricales.
