Observation 74040: Bondarzewia occidentalis Jia J. Chen, B.K. Cui & Y.C. Dai
When: 2011-08-14
No herbarium specimen
0 Sequences

Large cluster of stalked polypores that looked much like faded brown Laetiporus sp. at first glance. The tan colored cap and large, visible pores- and the fact that they are very fresh specimens proves otherwise. Fruiting from a large conifer stump with salal bushes.

Could either be Albutrellus sp. or Osteina obducta. 5th image shows specimen I brought home with yellow discoloration on pore surface and white spore print on the table top.

I don’t think this is Osteina obducta – The pores are too large and the cap surface is the wrong color.
