Inocybe lilacina vs Laccaria amethystina
Inocybe lilacina vs Inocybe geophylla
These two Inocybe are deadly toxic, whilst Laccaria are edible. Luckily, lots of differences! The colour on L amethystina can be quite similar to I lilacina when it’s dried out (see bottom right), so it’s really good to make sure you’re confident!
The gill spacing is also much wider on Laccaria, along with the tough stipe. Laccaria can be a little variable in cap shape, but don’t bear the umbo (bump) that Inocybe have on their caps, usually depressed in the middle instead.
I lilacina used to be considered a (lilac) variant of geophylla, but is now considered a distinct species.
