These are Auricularia auricula-judae, yes? These are on a dead & down aspen. I've never collected and eaten these before so I want to be absolutely sure. Is there any other species these could be confused with? If indeed they are, can anyone give tips about how to harvest them? and then, how to prepare them? From what I'm reading, they are have a higher water content than most other fungus and so will shrink greatly. I suspect there something like that black fungus you get in chinese restaurants.
