NW Lichenologists 2025 Calendar -- Sorry, sold out!

This year we are trying something different -- the first in what we hope will be an annual series.

We want this to be a collectible series, much more than a calendar, something that you will continue to USE year after year. Each year we will highlight a particular habitat, substrate, or species group. We also aim to introduce you to the fascinating world of crustose lichens.

This coming year's topic: crustose lichens on red alder. Ever wonder about the white "paint" that covers most alders in western Oregon and Washington? Here's your chance to learn something about them.

17 different crustose lichens are featured, representing the most common species you are likely to encounter. This is a great method to start familiarizing yourself with crustose lichens, since many of the lichens that you collect on this substrate will be represented pictorially in the calendar.

As a bonus, there is a monthly challenge. If you complete all the challenges we guarantee that you will be a lot more knowledgeable than when you started.

This 11 x 8.5 inch wall calendar, opening to 11 x 17 inches, has one month per page and characteristic crustose lichen species on the facing page. See if you can meet the challenge of the month! This is a limited edition, first come first serve.
