One of my favorite places to hunt. They are also useful for gaging whether an area is promising for collecting in (i.e. soil moisture and forest type).

There is a thriving population at this easily accessible location near Davenport. Any interested folks should go have a look.

I can’t be sure at all about the pictures where they look red. The stipe is hollow for the larger fb, so this makes sense as being in the R. foetens group. Based on the picture of the ones in the grass and their smell, they are likely in the R. pectinatoides/amoenolens/sororia group. Russula pectinatoides is a common grass Russula here in Tennessee, but you could have a different one. I’ve never heard of the foetid smell being washed away. Usually they are quite distinctly sweet and/or foetid. The rubber smelling ones can sometimes have a benzaldehyde odor but typically not. People are apparently working on this complex. Last I heard a decision has not been made for this group except that R. pectinatoides does occur in Europe and R. praetervisa is also a good species.

The smell of the gills could be described as “burnt rubber”. I found these mushrooms just as the sun was coming up, and they had endured hard rain in the hours before I observed them. I’m pretty sure these are all the same species, as they were growing in close proximity under the same tree. The “red” color on the young cap is intensified in this photo by long exposure in the low reddish light of dawn after a night of heavy rain. At noon it would look brown. In older specimens the color fades.

These are clearly one of the foetid russulas, but they lacked the sweet cherry smell I was expecting (could this have been washed away by the rain?), only the gills had the stink.

Is it a shrimpy/fishy smell or is it more like a foul, unpleasant smell? (I assume you are referring to the red capped ones and not the R. pectinatoides looking thing that probably smell metallic and like burnt rubber)

Not much smell up top, but the gills on these Russula are kinda stinky. They were coming up under scarlet oak at the rest area.
