I read this merely as not likely corresponding to any psychedelic compound known to occur in nature, not that it isn't psychedelic. Of course, even that isn't a given, since there could be some interaction between a known compound and a second compound affecting the metabolism of the first one. Although the description of its effects doesn't really sound like any psychedelic I've tried either, and I've tried quite a few

I'm still open to it being psychedelic(primarily acting on the 5-HT-2 receptor family) though. It could just be that there's enough folklore surrounding these mushrooms in the local culture to explain the very specific effects. After all, cultural beliefs are a part of "set and setting".
