Observation 21405: Bryoria Brodo & D. Hawksw.
When: 2009-05-14
No herbarium specimen

Notes: Characterization: Bryoria with
(1) pendent grayish brown thallus, darker brown near the base
(2) branches with projecting spiny side branches
(3) whitish soredia (and with isidia not evident in the soralia, at least at the resolution of these photos)

Identification: Hinds and Hinds (2007) report 11 species of Bryoria in New England. Five of these are common, at least to some extent, and may be distinguished as follows (summarizing from the key and descriptions in Hinds and Hinds):

1. sorediate Bryoria … 2
1. nonsorediate Bryoria … 4

2. thallus caespitose; soralia with isidia projecting from them like medieval battlements ….. B. furcellata
2. thallus pendent … 3

3. thallus light grayish brown, darker near the base; branches with numerous projecting spiny side branches; soralia without isidia; thallus K+ yellow …..B. nadvornikiana
3. thallus brown; branches somewhat thicker; soralia mostly without isidia; thallus K- ….. B. fuscescens

4. cortex K+ yellow or red ….. B. capillaris
4. cortex K- ….. B. trichodes

Bryoria are notoriously difficult, even with a good specimen like this. Recent (possibly unpublished) molecular studies are about to turn this genus completely on its head, too.
