Currently in New Zealand and blown away by the lichen assemblages here. Many familiar genera, but new species to me and boy are those macrolichens BIG.
Here are Sticta latifrons, Yarrumia colensoi, and Stereocaulon ramulosum from the Mt Aspiring national park.

Hey #lichen people,
I may do an alpine hike this weekend. I know some of the more obvious macrolichens of the alpine tundra, but are there any species that I should look out for specifically? Less obvious or understudied?

Macrolichens can look fluffier like moss but they're completely different. Lichen do not have roots or absorb water and moss does.

It's #YellowThu from #ColorADay featuring Brown-eyed Sunshine Lichen. Note the ice/snow on the Ponderosa Pine twig. Yep, that means you (folks in Pacific NW) can get a blast of color throughout the winter by finding this lichen.

Find old decayed stumps (left photo) and there's a good chance it will be covered with moss and #lichen, especially pixie cup lichen. Note the numerous light green 'eyelashes', zoomed in on right photo. These are named Smooth-footed Powderhorn lichen. Found: Pacific NW and eastern U.S.

Encountered Split-peg Lichen within 100 yards of Kootenai Creek trailhead on a rock about 16 inches in diameter (left image). 'Large' grouping worthy of note re: whitish/grayish green squamules numericallyabundant over rock and on some of the podetia. Had fun photographing 😊

Encountered this rock densely covered in at least three Cladonia lichen species...resembles a pincushion 😊 The right side image is a close-up of two different species. A third spindly species is near the top of the left image. Care to guess as to identities or just enjoy the colors/shapes 👍

So far; Macrolichens of the Pacific Northwest is ridiculously awesome, The Thing vs the Marvel Universe was kinda disappointing. Teaches me the value of sequential art; you’d think all splash pages of The Thing punching people would be the best thing ever.

Using ACCDC's species listings, it appears to be "Status unknown", probably due to a lack of sightings and potential misidentifications. I wouldn't doubt that that this is an at risk species, even if it's not classified as such right now.

That depends if you want coastal or interior resources. I use McCune and Geiser's Macrolichens of the PNW, which is good for most species, though one or two of the notes about habitat have been a little off for the BC Interior. Overall quality, but less accessible than bird field guides.
