The ones I found were growing on a log but Pholiota can parasitize living trees so I made sure to keep them in a non-mesh bag.
They're are edible and occasionally cultivated. I plan to try some soon because I can't resist trying something so scaly and slimy that looks like you shouldn't eat it.
Apologies to anyone still seeing duplicates of this post, programming.dev was running slow when I tried to post it and Jeroba was giving me timeout errors so I retried a few times ๐ .
