Variety of lichen - in response to @dber
Hey guys,
this is just a short post in reference to @dber's recent airport adventures.
Upon reading his last post about the indigenous lichen of Geneva airport I realized that most them appeared vaguely familiar to me. So I briefly went outside and tried to capture a few quick pictures of the biodiversity of lichen going on around here.
Bear with me if I fail to provide all the details of biological classification though, in that regard I'd rather refer you to @dber himself. But it certainly is interesting to take a look a something that has been around me all along but seems to have eluded my perception almost completely.

Do you know if lichen is edible @galotta?
Technically, most are edible, though there are some that are poisonous, so better to check before putting it in your mouth. I hear they are not very good tasting and have very little nutritional value, so probably not the first choice of what to forage for. If you are in an emergency situation, watch out for things like Wolf lichen which can kill! From one paper I read, it looks like there are more poisonous varieties than originally thought, maybe between 5 and 10%.

You even dropped references @yvesoler.. You're a legend! A true academic..
It is that nerdy side of me that loves to learn new things. If only I found a good way to keep all my references in order!
That's dope man. I think that's pretty special ish right there. Are you a student?
I research plan intelligence, plant music, and social innovation. Lichen is a personal favorite, as it is part algae, in conjunction with fungi, not quite plant, but photosynthesizes.... super cool, plus it is puurrttyyy. :)
