Observation 121149: Lactarius Pers.
When: 2012-12-25
0 Sequences

Notes:
These were growing under Live oak with caps up to ~ 9 cm across.
Latex was light yellowish, not profuse and mostly near the stem.
Taste was mild(double checked).
Spore print was white.
Spores were 6.9-8.2 X 5.3-7.1 microns,with low warts and some reticulation.
Spores were solidly in the broadly ellipsoid range with Q range of 1.15-1.30. Q(ave) = 1.25.
The spore size seems to eliminate L. rufulus which has globose to subglobose spores.
The spore size matches L. xanthogalactus although the mild taste and white spores do not.

The spore print was pretty thick

and it was definitely white.
The latex essentially came out the color you see.
There have been plenty of xanthogalactus fruiting this season and who knows all the things wet weather can do to a species. But these were plentiful and all of them had the same look, which was not quite xanthogalactus-like.

did the latex change quickly from white to yellow?

and could those “white” spores just have been a pale yellow?

according to the Bessettes’ Lactarius book, xanthogalactus can taste mild, too.

the rest fits pretty well.
