No specimen available

-This specimen was associated with the soil, and it was found growing next to hardwood.
-It was the only sample that was collected because it was solitary.
-There wasn’t a distinctive smell.
-The diameter of the pileus was measured to be about 11.5 cm.
-The surface of the pileus felt moist, slippery, lubricous, and smooth to the touch.
-The pileal shape was mostly planar, but the margins were undulating.
-The pileus was dark brown in color, and the flesh was revealed to be a lavender purple when the specimen was cut in half with my pocket knife.
-There were no significant or noticeable changes when the pileus and stipe were damaged.
-The cream/beige stipe was centrally located. The stipe measured to be about 8.0 cm in length and 1.8 cm in width.
-When the specimen was cut in half, it was observed that it was mostly solid and tapered at the apex. There were some areas where the stipe had some empty spaces. When it was touched, the material on the inside of the stipe felt soft.
-The stipe base was inserted/institious.
-Overall, the stipe looked shiny and fibrillose. Also, it felt slippery and lubricous. There weren’t any noticeable changes when the stipe was damaged.
-The dark brown gills were adnexed with a somewhat wavy pattern.
-It appeared to have two lamallae tiers that were arranged in a regular pattern.
-The spore print was dark brown.
-Under 40x magnification, the spores were oval shaped and smooth. They were brown in color. I used KOH reagent. They were easily found since they were numerous.
