Observation 191246: Boletus L.

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

It had a very unpleasant, garbage smelling odor.

The pileus was 9.2 cm in diameter, and it was a tannish brown color. Both the margin and the surface were smooth, and the overall shape was broadly convex. The inside of the pileus was both white and blue.

There were no gills found on this fungus, but instead there were dark gray pores. The pores were .5 cm thick, and from the stipe, they covered an area of 4.1 cm.

There was no annulus or volva on this fungus.

The stipe was central for the most part, but it also curved a little bit away from the center of the pileus. The outside of the stipe was smooth, and it was 6.4 cm long and 2.4 cm wide. It had a clavate, bulbous shape overall, and the inside of the it was solid. The outside of the stipe was reddish and tan, but the inside was blue, red, and yellow. With air exposure, the inside turned a dark color. The base was institutious.

A brown spore print was obtained for this fungus, and the spores had a pointed oval shape. They ranged from 8.0-10.0 × 3.6-4.0 micrometers.

After further inspection, HS41 may be a more mature version of HS29 in my group of collections, but I am still not sure.
