Whitish stipe,

shiny luster on cap surface, and lack of voluminous latex all lead away from L. volemus. Also, the central depression is a bit too sharply convergent for my idea of volemus.

Last summer I made several collections of a bitter-tasting milky with similar shape, color, and sparse latex. The one feature that didn’t match croceus was the lack of sulfur yellow bruising on the gills. An MO search of “Lactarius croceus” reveals other similar collections for which the bruising reaction color varies between yellow and brown, or appears to be absent. I suspect that there is a group of species for which the name croceus is currently applied. Bessette/Harris list the NA range of L. croceus as south to Georgia.

this would be the first L. croceus observation for Rich and Florida…

L. volemus is probably most common Lactarius species in FL, and these specimens share all characteristics of L. volemus.

The lighter yellow color can be explained by hotter days and decreased RH
