Observation 191538: Cerrena unicolor (Bull.) Murrill
When: 2014-10-10
No herbarium specimen

Notes: -This specimen was found growing gregariously as a shelf-like structure on a fallen hardwood.
-There wasn’t really a distinctive smell other than wet dirt.
-By looking at the specimen, it looked like a cluster because it appeared to have different and overlapping “caps”.
-Overall, the structure of this specimen was almost kidney-shaped.
-The diameter of the structure was measured to be about 17 cm.
-The surface was a cream beige color with some green algae growing on it.
-The surface was also dull, somewhat velvety to the touch, and somewhat wrinkly.
-When the specimen was cut in half, the flesh was observed to be white in color.
-The underneath surface revealed that the specimen was porous. The cream colored pores were incredibly small. It was also observed that some areas were dark brown in color, which was assumed to indicate bruising. [Note: It was already bruised when it was collected. However, it didn’t bruise when I damaged the surface with my pocket knife.]
-It was difficult to cut in half. The specimen was rigid but somewhat flexible towards the margins. It almost felt like I was cutting tough rubber.
-The spore print was cream/white.
