at this key to european species of the deliciosus group (sect. Deliciosi):
Some bruise or age green, others don’t.

European L. deliciosus sensu stricto can be seen on MO too: obses 52320, 64350 and 64359

Why on Earth would we even begin to call ours L. deliciosus then? That seems ridiculous….

On a similar note, does anyone have a link to a good European fungi site? Everything I read about L. deliciosus says bruising green. It would be nice to be able to refer to the mushrooms we named ours after, especially when they don’t really match up!

that’s the weird bit. The European one doesn’t get seasick.

I’m confused, Irene….

I know that the true L. deliciosus is a European mushroom, but are you saying that it doesn’t bruise green at all? Weird.

The name I proposed was L. deliciosus “group”, since I knew this was not the Euro version of it.

How about Lactarius amerideliciosus? Hahahaha…..

Thanks, Irene. I try to be good, but sometimes these habits are hard to break.

What Irene is referring to here (for those who don’t know) is that L. deliciosus is a European name for a mushroom that is similar in some respects, but is definitely a different species. We have been incorrectly using the name for a long time now, but it needs a new one.

L. deliciosus doesn’t bruise blue (or green) at all. This belongs in the deliciosus group, though.

Anyone seen L. deliciosus this bruised?

you’re right. It normally ages blue green in age, this one is just really beat up.

An oddly blue L. deliciosus?
