Observation 197225: Xylobolus subpileatus (Berk. & M.A. Curtis) Boidin

When: 2015-01-22

Collection location: Lower Meramec Park, St. Louis Co., Missouri, USA [Click for map]

Who: weed lady (Sylvia )

No specimen available

Many specimens on this log found with the fertile side facing outward – looking first a bit like a crust-type fungi. But the reverse side showing narrow zones of color. This certainly appears to be a dry and weathered group. Arora says they found are in groups, rows, fused masses or overlapping clusters. Pretty much the way they were. No pores can be seen with a 10x hand lens. Cap does look like it has matted hairs. Now through aging they have become dry and brittle – easy to remove.

Thanks for sharing your knowledge. Thought I had this correct. Wondered why I could not find any photos of Stereum hirsutum which looked like what I had found. I did see Xylobolus subpileatus in another location at the same park recently. With that find I could not remove any part of the fungus from the wood surface, so I did not see the reverse side. Interesting that I did see on MycoBank that the former name of Xylobolus subpileatus has had the name Stereum subplieatum in the past.
