Observation 154739: Russula sanguinaria (Schumach.) Rauschert
When: 2013-11-15
(57.75° -122.149° )
No herbarium specimen

Notes: I found these growing underneath a pine tree along with some Lactarius deliciosus. I tasted the cap and it was bitter. Under the microscope, spores were white and slightly ornamented. In Meltzer’s Reagent the spores stained blue (amyloid).


Note the slightly blue staining in the ornamentation of the spore. Taken in Brightfield with a 100X objective w/ oil. Sample in Meltzer’s Reagent.
