Sloppy Spore Print

May I also add that when I placed it on the sheet for taking a spore print it was reduced to a smelly liquid with very little remains of the cap. The stem had white mycelium??? possibly or something white growing on it.

the pores as shown are consistent with Gyrodon…

check google images for more examples.

also, the tough stipe looks like gyrodon.

we can all agree that sharper images make for better and easier photo ID, tho!

Gyrodon vs. Phylloporus

This discussion (interesting!) could have been reduced if the depth of the chambers was noted. Gyrodon seems to have very shallow pores or irregular cross-hatched hymenium, while Phylloporus should have deeper gills with cross-hatches between. I’m not sure, given the photographs, that any definitive statement can be made between them, except that when I enlarge the photos, the hymenium appears to have more pronouced gill structure than the cross-hatching between the gills, which would seem to me to be Phylloporus.

were there ash trees around?

if it’s Gyrodon merulioides, ash is a associate, but this odd bolete is NOT mycorrhizal! Apparently it does have a symbiotic relationship with an aphid parasite of ash trees, who live within the underground sclerotia (another very odd character to find in a bolete) of the Gyrodon. The fungus may then feed on the “honey” produced by the aphid. Truth is stranger than fiction!

this pup has irregular pores, not gills…

Phylloporus key

by Michael Kuo available at MushroomExpert.com. Need more data, as will be seen if you go to the key, to determine more than just the genus.

Yellow

I forgot to mention they had a nice yellow tint to them and the gills were weird, not straight lines but almost a “web” structure.
