Growing from pine

These were without question growing from pine, as do all the other ‘Gymnopilus ventricosus’ I encounter in this region. Also, the color of the caps may be slightly misleading as they’re coated with a copious amount of spores

These don’t seem to big to me at all, the blue bruising is nowhere near consistent enough of a feature to be used as a basis for identification in this species group, these are the wrong color for ventricosus, the wrong shaped stipe, no veil remnants on the margin and there are enough deciduous leaves in the picture that substrate exclusivity cannot be reliably ascertained.

notes say: “Growing on Pinus radiata stump”

also, G. viridans fruits off of conifer wood as well.
the type was found on a burnt coniferous log.
these also lack the blue bruising and seem way too big.

Nice find!

Fries described Agaricus junonius as a small statured, pale yellow mushroom growing solitary on fallen logs. The current concept is dubious. On the west coast, most large Gymnopilus will most likely turn out to be G. ventricosus. Collections found near hardwood with ocher colored pilei and regular to slightly clavate bases are probably going to turn out to be G. viridans.
