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
