Every other year NW Lichenologists meets for certification for macrolichens in the Pacific NW of North America. Two subgroups attend: those wishing for more training and those taking the certification exam. Check out the info here: northwest-lichenologists.wildapricot.org/page-1854192

Occasionally, we get to travel to the NW fringes. Recently, the Calif. Lichen Soc. forayed to San Luis Obispo. How could we not want to see that area too? So, here are few specimens from the Los Osos. Our IDs are
Usnea rubicunda
Heterodermia leucomelos
Lecanora caesiorubella
Your input on them?

Stereocaulon dactophyllum is today’s lichen hit. And because I am feeling generous, here’s a Pannaria rubiginosa.

Are #lichens truly a treasure chest of #naturalproducts compared to non-lichenized #fungi? We put this to test using #BGC count as a proxy across ~400 #genomes.
Spoiler alert: They absolutely are!

A big revision for the Lecanora saligna group -- six new species in Lecanoropsis. This is a common group of crustose lichens in western North America and elsewhere in the Northern Hemisphere.

Sometimes you just need to sit back and stare at rocks, or at least the exciting things covering them like this one here with Rhizoplaca, Xanthoria, and others. -Seen in Central Oregon over the weekend, along with Umbilicaria phaea and what keys out to be U. krascheninnikovii on nearby rock. #lichen

Hypotrachyna sinuosa a widespread species commonly encountered in low elevation riparian forests in the Pacific Northwest, seen here on Oregon ash in a riverside swamp in Lane County, Oregon.

Nothing is more satifying than seeing the intrepid inventory work of a group of lichenologists tracking rare to even common lichens. Here we are on the Oregon coast last week looking for Erioderma, Leioderma, & Sulcaria, as well as a host of Cladonias and others. Pannaria oregonensis is shown.

Sometimes you hit the TRIFECTA-Lichens, rare birds, and old-growth, as the folks from Evergreen State College did during their group talk on lichens and marbled murrelets at the NW Lichenologists/Scientific Assoc. meeting talk Wednesday. Their mentor, Dr Calabria is leading the way. #lichens

How about the specimen of Sphaerophorus! I am learning towards S. venerabilis, but you can set us straight. It's from Mary's Peak in the Coastal Range of Oregon.

eDNA and traditional biocrust sampling each have blind spots for biodiversity but tell a similar ecological story of disturbance in Artemisia steppe.

So here is a recently observed specimen from Crater Lake National Park here in Oregon. Anyone want to put a name to it? I don't think this will be too hard. The Genus should be easy. And by the way, you gotta love your parks! #lichens #lichenologists #NPS #NationalParks
