One of the coolest things I've learned recently is that lichens facilitate the establishment of some Dudleyas (cool CA succulents) on the south coast of California. One very rare D. species is a lichen obligate!

Save the date! The California Lichen Society's 2019 annual meeting will be Saturday, January 26 in a very licheny spot near Winters, California. Official announcement forthcoming soon!

CALS annual meeting: Join us Jan 25-27 (main events Jan. 26) at the UC Davis Quail Ridge Reserve near Winters, CA for lichenizing, socializing, and learning about recent research. It's a beautiful spot with fantastic lichens. Everyone is welcome! ow.ly/9QCI50jS47W

This year's evening presentations (after dinner on Jan. 26) will feature three early career lichenologists talking about their exciting research: Kevin Ball (staining lichen yeasts), Chris Adlam (lichens and fire in the Klamaths), and Allie Weill (chaparral lichens and fire)

Quail Ridge is where the CA lichen society will be having its annual meeting Jan 26- nice summary of lichens to expect, and we'll surely add to the list. QR is just far enough out of the central valley that some cool cyanolichens and other air-quality-sensitive species occur.

Please join us for the CALS annual meeting at the beautiful UC Davis Quail Ridge Reserve near Winters, California, January 25-27 (main events on the 26)! Free and open to the public, but RSVP required.

Soredia are an effective means of (asexual) reproduction, both main partners wrapped in a dust sized package, spread on wind or bird's feet. Largest here 30 microns diam. (typical for many soredia). Human hair c. 75 microns diam.

#lichenJanuary kicking things off with a probable chestnut fence festooned with lichens! Nice to see the new post with the older rails. Close up is young Xanthoria parietina surrounded by Physcia adscendens (and a small bit of P. tenella) with Parmelia sulcata too

It's #lichenJanuary! To celebrate, share your lichen photos from California and beyond all month. #CAlichens

The CALS annual meeting and field trip will be Jan. 25-27 in Napa County. Join us! Here's the fb event page: facebook.com/events/2207737… #lichenJanuary

I only know how to identify two types of lichens: cool ones and very cool ones. Here’s some pics from #yosemite and you can decide if these lichens (and bryophytes) are cool or very cool #lichenJanuary

The California Lichens annual meeting and field trip is kicking off at the #UCDavis Quail Ridge Reserve. Stay tuned for our exciting discoveries! Chaparral ecosystems can involve some extreme lichenizing, as Allie Weill demonstrated last winter. #calichens #lichenjanuary

Bold lichenologists getting deep in the old growth chaparral in pursuit of Hypogymnia gracilis and the elusive cyanolichens #lichenjanuary #napa #calichens

Fantastic presentations by my former #ucdavis lichenology students Kevin Ball, Christopher Adlam, and Allie Weill at the California Lichens annual meeting tonight. So cool to see how their research has progressed since 2017! #lichenjanuary
