Observation 191250: Agaricus porphyrocephalus F.H. Møller
When: 2014-09-10

Notes: This fungus was found growing directly on top of grass in dense, moist dirt. Many large oak trees provided plenty of shade as coverage.

It had a regular mushroom smell.

The pileus was 8.9 cm in diameter, and it had a light brown color with some brown patches on the surface. The pileal surface was smooth, and the margin was smooth with some light scales toward the middle. The overall shape ranged from broadly convex to depressed, and the color inside ranged from light rose to white.

The gills of this fungus ranged from a light pink to a dark brown color, and they were all adnate. They had an even margin, and from the stipe, they ranged from 2.4 -2.9 cm long. They were approximately 1 mm wide, and they were spaced apart about 1 mm.

There were no lamellae present in this fungus, but a single-edged, creamy annulus was present around each stipe.

The stipe was both central and smooth, and it ranged from 4.9 – 6.0 cm long to .7 – 1.2 cm wide. The overall shape was bulbous toward the bottom, and the inside of each stipe was solid. The outer color of each stipe was creamy white, and the inside ranged from rosey pink to a cream color that turned slightly brown after being exposed to air.

There was no volva on this fungus.

The spore print turned out creamy white, and they had an oval shape. They ranged from 6.0-7.6 × 3.8-4.4 micrometers.
