UV fluorescence

UV fluorescence – attempts at photos.

Ochrolechia of interest… if UV+ orange, then it keys to O. arborea.  If UV- or UV+ white, then O. gowardii.  Alone, the UV response appears somewhat yellowish to me… (more so than the photo suggests). I have been tempted to call it closer to orange.

When I think of UV+orange, I mainly think of the medulla of Esslingeriana idahoensis, which leaves no doubt of its orange color…

Meanwhile, Cladonia portentosa is described as UV+white…

 

Logging of Wells Gray

Original Post (August 28, 2012):

I received this email from Trevor Goward today and intend to lend my support. I visited the area back in the 1990s and it was fantastic!

Dear lichenologists

A local forestry company is gearing up to log a critical
portion of the Clearwater Valley near Wells Gray Park.

Because this valley supports one of the world's richest
macro- and mesolichen floras - more than 430 species
recorded so far - I'm asking the lichenological community
will help us put a stop to this.

There are three ways you can help:

(1) Link to the following website:
http://wellsgrayworldheritage.ca/. Doing this will make
clear to the B.C. government that this is more than a
local issue.

(2) Share this link with your Facebook friends, with a
request that they pass it along.

(3) Write a letter of support. If you've ever visited the
Clearwater Valley and would like to help us out in this
time of crisis, please drop me a line
(trevor.goward@botany.ubc.ca) and I'll send you the
details.

Many thanks to all

Trevor Goward

Calicioid Checklist and Key

Back in the 1990s I did quite a lot of work on calicoids, particularly in the temperate Pacific Northwest.  That work tapered off for a while due to jobs with other focus plus young kids.  Well the kids are getting more independent, so I’m reviving my work.  I hope to focus more on conservation than taxonomy, but strong taxonomic understanding is still a foundation for good conservation decisions.

The calicioid flora of western North America is still poorly understood.  Many species here have either not yet been reported for the region, or even for North America.  Some remain unknown to science entirely.  To get a foothold on understanding our flora, species worldwide must be considered.  Therefore, my checklist and keys attempt to cover all species named in contemporary literature.

I’m sure there are still names attached to specimens a hundred years old or more, which are not covered.  I’ll leave the extreme sleuthing to people with a primary focus (and job) on taxonomy.  But this should be sufficient for building knowledge of which species are here, how frequently, and in which habitats.

New keys in progress

They are just starting to form, and are quite draft, but will include species descriptions and more. Click here!
