Common Name: none

Unknown
It is not known how common Pluteus pouzarianus is in California, since it would usually be misidentified in the field as Pluteus cervinus. Macroscopically the only differences are the slightly greyer cap of Pluteus pouzarianus, the usual lack of a raphanoid smell, and its growth on coniferous wood rather than the hardwoods that Pluteus cervinus inhabits. With the aid of a microscope we can see that Pluteus pouzarianus, in contrast to Pluteus cervinus, has clamp connections in the pileipellis which is a cutis of two layers, a hyaline layer over a brown pigmented layer.
