I trust your opinion very much. Take it easy, buddy!
I can see holes above the tubes and near the bottom. How can you tell which were created first?
There are larvae present, and they appear to have came from the bottom.
“as if”? Really?
the only possible beetle holes I see are at the top of the photo, not the bottom. That’s why I asked if the photos were upside-down.
The hymenium covering the bottom portion of the sporocarp is generally where the beetles bore in. I have not seen holes on the top of any Cryptoporus volvatus.
On one of the other photos, there may be a hole on the right-hand side of the sporocarp: again, an atypical location for a beetle hole. But as you have already stated all photos are right-side up. we have to take your word for it.
In my experience C. volvatus is very geotropic, always orienting itself so that the tube point downward, toward the ground. In photos 2 and 3 the tubes point upward, toward the top of the photo. Ergo, this cannot be Cryptoporus volvatus as I know it.
The bottom of the crypt has just rotted away, I assume.
The specimens in photos 2-3 are DECOMPOSING.
They show tubes pointed upward from the bottom of the photo: a very unusual orientation for the polypores. That’s why I asked whether the photos were posted upside-down.
I hope you are correct and these are Cryptoporus volvatus. But that can’t be correct UNLESS the orientation of photos 2 and 3 are upside-down.
photos 2 and 3 are taken from the bottom. I can easily see the bottom opening in these pics, but the opening always is on the side pointed downward, at least in all cases of C. volvatus I’ve seen. In other words, if photos 2 and 3 were taken underneath the fungus and the photo orientation was swapped 180 degrees.
This would then be a good match for C. volvatus in Smith, Smith and Weber: “… margin extending downward to form a veil-like covering over the pore surface; …”. The key also states: “Pore surface covered by a membranous layer of tissue which is sometimes perforated by 1 or more worm holes”; and the description adds "The “worms” nearly always found in the interior can be used as fish bait."
I’ve long noticed a pleasant fungal and slightly resinous aroma to C. volvatus when young, fresh and white inside.
Not sure of tree species, I was a little out of it by the end of the day.
Same species, different ages.
Photos 2 and 3 look very different to me than the rest. Very old remnant sporocarp, maybe? C. volvatus should have an apical pore near the base of the fungus (point closest to the ground). Bark beetles use C. volvatus for protection to survive the winter. When they emerge the following spring, they are coated in spores, which they transfer with their eggs to the next tree they infect and lay their eggs in: usually a tree already environmentally stressed.
In the sectioned specimen, there does appear to be a hollowed interior, with tubes, but they don’t look oriented downward. The bottom pore is either missing or is not oriented downward.
The shellac-like orange surface is suggestive of fresh C. volvatus in the first photo.
A note on what tree species the obs. is growing on would be helpful, and would probably support your identification. For those of us who have not been to Leavenworth, WA and know the tree species.
