Esslingeriana idahoensis' medulla glows bright yellow beneath a UV light! Lichens are so cool.

I’ll be working as a guide and naturalist up in Alaska this summer, and really want to focus on the lichens there, particularly in the Kenai Peninsula area. I’ve got a list of general lichen books to check out, but was wondering if anyone knew of a good Alaska specific field guide? I’d prefer something physical, as I won’t have internet access, but electronic resources are welcome too.

Thank you!

Just created a new sub to trade mosses and lichens and such! I would love to see you all on r/MossSwap :)

Hey everyone! I'm a second year Environmental Science student at university in the UK and me and a colleague are doing a project on trace metal concentrations in lichens in particular sites. Specifically we are looking at Cd, Ni, Pb, Cu and Zn. We will be using an ICP-AES machine to analyse these samples and as a result require standard solutions for each of these metals (expected concentrations in the lichens)

I was wondering if anyone here could help us with those values. If anyone wants more details feel free to DM me!

Thank you.

Hello y'all,

I'm interested in reading about any fertilizing effect that arboreal lichens have on the soil beneath a host tree's canopy. My thinking is that, since lichens get their mineral nutrition from dust and atmospheric gasses, the decay of shed bits of lichen into soil beneath a tree may concentrate gathered elements there in a way that is useful to the tree (with the corollary that a tree may benefit from encouraging epiphytic lichen growth) or to understory vegetation. Are y'all aware of any research that's been carried out to this end?
