Observation 191534: Polyporus squamosus (Huds.) Fr.
When: 2014-10-10
No herbarium specimen

Notes: -This specimen was associated with a dead hardwood stump, and there were 2 clusters that were found. In one cluster, there were 2 broad caps coming from one lateral stipe.
-Upon smelling the specimen, the odor wasn’t unpleasant. To me, it smelled like the rind of a watermelon.
-Of one sample on one of the clusters, the diameter of the cap was measured to be about 49.9 cm.
-The orange brown surface of the cap was smooth and mildly scaly.
-Overall, the cap was mostly planar, but there was only slightly indented. As www.mushroomexpert.com put, “it was kidney shaped.”
-The pileus margin was smooth and not striate.
-When the cap was damaged, there wasn’t a significant or noteworthy change.
-When it came to cutting the specimen in half, it was somewhat difficult to cut with my pocket knife.
-The creamy white flesh was “juicy” when it was touched, cut, or squeezed in a sense that liquid came out. It was assumed to be water since it took a relatively longer drying time. Droplets were also found underneath the surface when the specimen was still fresh.
-The sessile or lateral stipe was mostly dark brown in color, but the outside surface was black.
-When the stipe was measured, it was about 6.8 cm in length and about 9 cm in width. (The stipe was also tough to cut.)
-When the stipe was cut, it was observed to be solid.
-The base of the stipe was assumed to be inserted/institious because it was attached to the hardwood.
-This specimen was porous which were a light tan or creamy white color.
-It was also noted that the pores of this specimen was irregularly shaped like a “honeycomb” as www.mushroomexpert.com described it.
-The spore print was a medium tan/brown color.
-Under the microscope (40x magnification), the spores were smooth and elongated.
