Observation 81527: Laricifomes officinalis (Batsch) Kotl. & Pouzar

When: 2011-10-29

Collection location: Little Kachess Lake, Easton, Kittitas Co., Washington, USA [Click for map]

Who: P. Hill (phill)

No specimen available

This is usually described as requiring old growth forest and growing on an old snag (upright dead tree). Thus is an unusual example for it is neither in old growth nor is it on a snag. Yes that is my shoe and no I am not in a tree. I think you can just make out that this “Agarikon” is growing on a horizontal downed log. It is on its typical host here in the Pacific Northwest — a Douglas Fir (Pseudotsuga menziesii).

The log happened to be hung up on the side of a rock slope, possibly providing a similarly drained and sheltered location to it usual habitat on an upright snag.

It is also a handy example, because it is an easy walk from a paved road.

I found it at approximately 2400’ feet elevation (730m) high in the Cascade Range in the State of Washington.

I’m guessing that if the layers we see are each one year of growth, this is about a 30 year-old specimen. I did not check the bottom of this polypore to see if it appeared to still be growing.

Mine was found by road side. Area around me was 3rd growth but the tree it fell off was easily 400 yrs old. Its almost as if they spared one of the biggest trees in the forest from being cut.
