Stereum ostrea

Stereum ostrea


One of the false turkey tails. It resembles the ‘True turkey tail fungi’  Trametes versicolor, in that the cap is covered with algae and it grows horizontally out of rotting wood. This species and it’s very close look alike Stereum hirsutum can be distinguished by the size of the cap. S. ostrea has relatively large   caps. No spores could be found which is not uncommon. The bottom of this mushroom has no visible pores or gills, because it is actually a scum mushroom, that is just pretending to be a poly pore.
