    The NW Lichenologists calendar for next year is now available.


    The coming year's calendar highlights the spectacular photography of Jason Hollinger with entertaining and informative captions by Jason and Nastassja Noell. Plus they provide short bios for five historical figures important in the development of lichenology in western North America.

    This 11 x 8.5 inch wall calendar, opening to 11 x 17 inches, has one month per page and a photo of a charismatic lichen on the facing page. This is a limited edition, first come, first serve. A list of lichens included is given on the NWL website's calendar page.

    We have a new offering from NW Lichenologists, a handy, compact guide to Usnea in our region.

    See below for a general description and the Store section of the NWL website for more details. Note also that we have a limited time discount if you order the 2019 calendar and the booklet together.



    Usnea in the Pacific Northwest,  Aide Mémoire

    by Daphne Fisher Stone, illustrated by Hannah Wilson and Rachel Werling

    ISBN: 978-0-9790737-3-1 (pbk.)

    Cost: $12 per copy + $3 for domestic shipping and handling for 1-10 copies. (For example, 3 copies would be 3 * $12 + $3 = $39. One copy is $15 including shipping.

    Inspired by an "Aide Mémoire" booklet produced by the British Lichen Society, this booklet provides a compact reference to Usnea in the Pacific Northwest with black and white line drawings, identification tips, and more. It should be useful to professionals and beginners alike. At the top of each page is a general statement about where the species is found in the Pacific Northwest. Each page shows several sketches. At the top left is an “icon” intended to show the general growth form. The icons used are tufted and bushy; pendulous without fibrils; pendulous with fibrils; and several with a special form or coloration, including Usnea lambii, U. longissima, and U. silesiaca. On the top right is an illustration of a large branch, cut in half lengthwise and also cut across the branch. This shows the relative thickness of the cortex (C), medulla (M), and axis (A), a useful tool for identification. Below the first two sketches are one or two sketches showing characters on main and secondary branches. A few words indicate characters that are typical of the species, such as soralia shape, isidia, papillae, and dents in the main branches. You may notice that on most species I do not describe branching patterns. This is because most Usnea thalli that are collected are not perfect, mature thalli, so branching patterns are not usually obvious. The bottom of each page lists similar species and some differences between them and the highlighted species. At the end of the booklet is an illustrated glossary.

    Cemetery Lichens - Mount Pleasant Cemetery, Seattle

    ​Why not consider lichens as an alternative for Hallowe'en?  Lichens are friendly and interesting organisms that love to grow on headstones and old trees. They are harmless to your plants and add aesthetic value to trees and shrubs.  We can actually use them as indicators of air pollution!

    Katherine Glew is offering a 2 hour lichen experience at the Mount Pleasant Cemetery in Seattle, on Saturday, October 27 from 10:00am to noon. This offering will occur - rain, shine, wind, snow.........

    To sign up for the course and read a description, go to the following link:

    Bring a hand lens to view lichen details

    Cost: $30 per lichen enthusiast

    The Central Puget Sound Chapter of the WA Native Plant Society, east side, will host a presentation on lichens by Dr. Katherine Glew from the University of Washington Herbarium, Burke Museum of Natural History.

    Dr. Glew will introduce lichens through photos and field material. The importance of lichens in the forest and all environments will be discussed. Lichens are part of most ecosystems and contribute nutrients from which other plants can benefit.

    Fun lichen facts will be shared, such as using them for creating the dyes in Scottish kilts and the making of lichen schnapps in Iceland. Did you know that lichens can be used as indicators of air pollution? They also have medicinal properties that have been use over centuries. Join me in discovering these fascinating fungi that form partnerships with green algae and cyanobacteria.

    Forest Service jobs for 2019 are now being advertised. You will only have until October 12, 2018 to apply for next spring/summer jobs! I recommend you apply now even if you aren't sure what you'll be doing next year because this will be the only opportunity to apply for Forest Service seasonal work. You'll want to search for Biological Science Technician Plants or Biological Science Technician Natural Resources (for GS-5). If you are interested in lichen focused work be sure to apply for positions in John Day Oregon (Malheur NF). The job won't require residence in John Day and the work takes place all around OR and WA.

    Overview: Please join Darwyn Coxson, Yngvar Gauslaa and Toby Spribille in BC’s beautiful Upper Clearwater Valley for some enlichened walks in the woods with three leading researchers whose work is revolutionizing our understanding of lichen morphology, lichen response to ecological signal, and the lichen symbiosis itself. 

    Scope: Set against the wilds of Wells Gray Provincial Park, this workshop will bring you up to date on some of the new findings and insights of lichen ecology, with emphasis on their field application. Our discussions will be wide-ranging, and partly determined by the participants; but likely we’ll focus on the ecological behaviour of genera like AlectoriaBryoriaLethariaLobariaRamalina and Usnea

    Events: The workshop will include daily field outings, evening lectures, and group discussion around the campfire and/or in break-out groups. Please bring along your questions for Yngvar, Toby and Darwyn.

    Participants: Capped at 20 people, this workshop is ideal for amateur and professional lichen enthusiasts with a good working knowledge of the common lichen genera. 

    When: Lichen Revival IV will begin Thursday evening (30 August) at 6:30 PM with a mixer, group welcome, and lecture by Toby Spribille. It will run through Friday and Saturday, ending early Sunday afternoon. This should give participants plenty of time to make it home on Tuesday for school or work.

    Where: The workshop will be held in the Clearwater Valley near the southern portal of Wells Gray Provincial Park – a vast protected area six-hours northeast of Vancouver and two hours north of Kamloops: Wells Gray Unlimited! / Wells Gray World Heritage.

    Venue: Indoor portions of the workshop will take place in a rustic one-room school house located about 20 minutes north of the village of Clearwater. For much of the time, however, we’ll be out tramping about in contrasting habitats within easy reach.

    Note: All proceeds from this event will go to the Wells Gray Wilderness Society, dedicated to educating young people concerning the wilderness and other values of the Clearwater Valley.

His work focuses on the components necessary to make symbiosis work. He is currently based out of the University of Alberta. His evening lecture is titled Definitely not IKEA: Lichen assembly and the search for the missing instructions.

    photo of Yngvar GauslaaYngvar Gauslaa is professor in botanical ecology at the Norwegian University of Life Sciences. His ecological and ecophysiological studies have contributed new insights into lichen distribution, growth and acclimation to environmental factors like light, rain, dew, humid air, as well as into biotic factors including logging, air pollution and grazing. This is his fifth visit to the Upper Clearwater Valley. His talk is titled: Lichens: Key to understanding local and large-scale variations in humidity.

    photo of Darwyn CoxsonDarwyn Coxson is Professor of Plant Ecology at the University of Northern British Columbia. His research has focused on the role of lichen communities, and lichen associations such as biological soil crusts, in ecosystem function, measuring parameters such as carbon gain and nitrogen fixation. Dr. Coxson was a co-author of the 2011 UBC Press book “British Columbia’s Inland Rainforest: Ecology, Conservation, and Management”. The work of his research group in the Inland Temperate Rainforest was one of the major factors in the 2016 designation of the new Ancient Forest – Chun T’oh Whudujut Provincial Park, protecting important Ancient Cedar stands and adjacent wetlands in the Robson Valley. His evening lecture is titled: Living life on the edge: How lichens thrive in harsh environments.

    More Information: Participants registered by 5 August will be sent an events schedule, details on accommodations, and recommendations for weather, footwear and clothing. Suggested readings will also be provided.
