Observation 188140: Russula crustosa group

This fungus was found growing directly on top of grass in dense, moist dirt. It was shaded by many large oak trees as well.

It had no distinct smell to it.

The pileus size of this fungus ranged from 2.7 to 10.1 cm in diameter, and it had a greenish blueish gray color to it. It had a smooth surface and a patched margin. The pileus shape ranged from broadly parabolic in the immature fungi to depressed in the more mature fungi. The inside of the pileus was white.

This fungus had adnate gills that had an even margin to them. They were white in color, and they were approximately 1 mm thick. From the stipe, they were approximately 4.4 cm in length, and they were spaced approximately 2 mm apart from one another.

None of the forms of this fungus had lamellae, annuli, or volvas.

The stipe of this type of fungus was central to the pileus, and it was also smooth. The length ranged from 3.7 to 7.1 cm, and its width ranged from 1.8 to 2.4 cm. The base of the stipe had a clavate shape, and the inside of the stipe was stuffed and spongy. The inside of the stipe was white, and so was the outside of the stipe. Its base was institutious as well.

The spores for this fungus were white. The spores’ shape was ornamented, and their size ranged from 5.6 to 6.4 microns in diameter.
