Observation 112735: Ganoderma P. Karst.
When: 2012-10-07
No herbarium specimen
0 Sequences

Huge Ganodermas starting to degrade on an 8-foot diameter Western hemlock snag. Notice how the rings of fungal growth seem to be breaking down along those same growth rings. Each old sporocarp was at least 15 inches across, and close to 10 inches deep.


Old-growth Western hemlock snag with Ganodermas. Snag is too tall to be visible with all Ganodermas on it, so turn photo to the left 90 degrees to show actual snag.
Ganoderma, about 15 inches across the top. I believe this may be the oldest sporocarp I’ve ever seen.

Ancient Ganoderma breaking down along the growth rings. This specimen may have reached 18 inches across.

Recognized by sight: These huge, very old Ganoderma are growing from a similarly huge Western hemlock snag. The Laetiporus conifericola was found on the opposite side of this snag. I would estimate the snag to be 8 feet in diameter, more or less, at the base. This is the first example of older Ganoderma specimens I’ve seen showing any signs of decomposition. How long have they been degrading? At least 20 years, perhaps more I’d guess.
