Observation 14422: Russula Pers.


I’ve added a focus-challenged shot of the gills.
This is as shot of the environs which includes the local live oak (q. virginiana).

That place – suitable for a fairy tale..

Another possibility

is Russula maculata. I can’t see any pine needles, it sure looks like a hardwood habitat, and I don’t find it impossible with plenty of oaks in a place called “Washington Oaks Gardens State Park”…

But the point is if the trees in the area were observed. That is very important to narrow down the number of possible species. Another thing is to check if it is acrid, bitter or mild, also how large part of the cap cuticle that can be peeled off from the margin towards the middle. The next level is to find out colour reactions with different chemicals.

I really have no idea how many red Russulas with yellow gills there could be in Florida.

in the lower right corner. One leaf might be an oak leaf.

But do these grow with pine?

Couldn’t it just as well be Russula pseudointegra (that grows with oak)?

Those look dried out

while these look fresh.

Probably not the same cessans then

It seems like the american Russula cessans (ss Thiers ?) isn’t quite the same as the european, which was described from England and grows with Pinus (silvestris).
Here are good pictures of what I’d call Russula cessans:

At this time of the year, with yellowish gills, it could be R. cessans. However, a good closeup of the gills would help tremendously. R. cessans has distinctly yellowish gills and has the occasional short gill, unlike most russulas. (Most have white or very nearly white gills, lack short gills, or both.)

Aside from that one distinctive species, red-capped russulas tend to require microscope work to identify to species.
