Observation 191150: Russula densifolia Gillet

This fungus was found growing underneath the shade of trees in an area with lots of grass and very dense, moist soil.

It had a slight earthy, grassy smell.

The pileus of this fungus was 8.2 cm in diameter, and it was both brown and black in color. It had a smooth surface, and its margin was both smooth and uplifted. The shape of the pileus was infundibulum. The inside of the pileus was white, but it turned a brown gray color after it was exposed to the air.

The gills were adnate, and they had an even margin. They were white in color, and they were .25 mm wide. From the stipe, they were 4.1 cm long, and they were spaced .25 mm apart.

The stipe was both central and smooth. It was 3.2 cm long, 2.1 cm wide, and it had an equal shape. The inside of the stipe was solid and white, but after it was exposed to the air, it turned brown. It had an institutious base.

The spores of this fungus were creamy white, and they had an ornamented shape. They ranged from 5.6-7.4 micrometers in diameter.

Some other interesting characteristics are that the stipe felt slightly chalky, and the gills turned a dark color when they were touched.
