Observation 106274: Bryoria Brodo & D. Hawksw.
When: 2012-06-13
(47.4054° 116.4256° 703m)
Herbarium specimen reported

Notes: 6/13/12 Coll. #6B

Substrate: P. ponderosa, ~20 years old; height 6ft from ground.

Thallus: 5.2 cm long, 1.5 cm across. Greenish brown from far away, lighter up close, slightly brittle. Main branches 0.4mm across, the rest less than 0.2mm, somewhat faveolate. Pendant.

Soredia: white speckled with some dark, wider than the branch it emerges from, abundant.

Chemistry: K-, KC-, C-, P+R soralia, P+Y cortex (I think)

Pseudocyphellae: not seen.

Based on chemical features: chemical tests match up with both this as B. fuscescens, but the occurrence at the refuge of Pseudephebe pubescens and a PPD- sorediated Bryoria, that is potentially B. simplicior opens up the possibility of this being B. lanestris, long shot, but a possibility.

So I just came across another Bryoria with soredia that tested negative for PPD (tested 3 so far along with a control) and other chemical tests. This and some other features indicate it may be B. simplicior though bizarre to be here as far as range. But if that sample turns out to be B. simplicior, then this sample on this here page has the potential of being B. lanestris which CNALH states that they are often found together… long shot due to their known habitat being is much higher in elevation, but a possibility… Pseudephebe pubescens observation 95810 was found that at this location and thats one thats not easy to mistake, and its range is seemingly restricted to a similar range as B. lanestris and B. simplicior

Ve have vays of making him talk…

Yay!! P+red soredia… now for the rest of the tests….

B. simplicior…

I ran into him too, but then looked at the CNALH maps, and he seems to only travel up in the mountains and up farther north – even the ones south of refuge are in Utah at 6,000ft and 11,0000ft in Arizona, that doesn’t seem like it could equate to 2000ft up here… I’ll test again! With another instrument :)

I should’ve known you were being thorough!

Then I’d tentatively call this B. fremontii. Is the “trunk” branch really coarse and thick? You won’t necessarily find any yellow pseudocyphellae or soralia or medulla.

(Wait: I see there is something called B. simplicior in the B. fuscescens group with PD- soralia. Maybe that’s our man?)

Totally did a control check with Cladonia

before I did my second run through on all the specimens, cause the first run was so weird getting so many negatives. especially the soredia. For the Cladonia’s I got orange for a squamulose species, red for a podetiated species… so maybe I’m making each batch differently somehow, which is possible, cause I have to make a new batch before each run cause the eyedroppers drop out so much liquid with each drop, argh – they even pick up the crystal fragments!!

All negative theoretically can only be B. fremontii

But this looks more like B. fuscescens. You’re sure of your P test? (If ever at all in doubt test it on one of the (many) browned fumarprotocetraric Cladonia species.) It’s not fleeting, but it can take a minute or two to develop. And you might only see it on the soralia. (By the way, P+o/r branches – when you finally find one like that! – is not a sure sign of B. glabra, you really need to check the shape of the axils and texture of the branches… or have an expert look at it, haha! :) B. glabra and B. fuscescens can be devils to distinguish.)
