No specimen available

-This specimen was associated with the soil, and it was found growing as a cluster at the base of a hardwood tree.
-The odor wasn’t distinctive or necessarily unpleasant.
-The diameter of one of the caps was 9.2 cm.
-The surface of the pileus was dry, dull, and smooth.
-The pileal shape was somewhat flat.
-The overall color of the specimen was a rich medium orange color.
-Underneath the cap, the gills were light peach in color.
-The medium tan/orange colored stipe was centrally located, which measured 11.7 cm in length and 1.2 cm in width.
-When the stipe was cut in half, it was discovered to be solid and equal.
-The base of the stipe was considered to be caespitose because they were growing as a cluster from one single spot.
-The surface of the stipe was dry, dull, and appeared to be fibrillose (having tiny hairs).
-The gills were considered to be decurrent and even in margin.
-I would describe the color of the gills as a typical pumpkin orange.
-It appeared to have four lamellae tiers with a crisped gill pattern.
-The spore sprint was assumably white because it was hard to determine on the piece of paper that was placed underneath. However, the spores were light in color.
-Under the microscope, there was an appearance of elongated and round spores. [The proposed specimen was expected to have round spores.] Therefore, there may have been some contamination during the process of measuring spores. A new picture will be provided soon.

[Note: Pictures of fresh specimen was lost. Photo credited to user halstapl. The picture of the dried speciment was of from my own collection.]
