Observation 209906: Lactarius petersenii Hesler & A.H. Sm.
When: 2015-07-13
No herbarium specimen

Notes: > A scattered group of several fruiting bodies growing in the middle of the blue-blaze trail in mixed woods (pitch pine and oak) of the Speedwell section of FPP.
> Injured gills instantly oozed copious pinkish-brown latex; the latex eventually stained the gills brown upon drying.
> Odor not entirely unpleasant, but sharp and rather acrid.
> Keyed out well and matched the description and pix in the milkcap book.
> The wording in the books suggests hemlock as the symbiont, but there surely no hemlock in the NJ Pine Barrens!
