Observation 34116: Cladonia furcata
When: 2010-02-20
No herbarium specimen

Notes: Location: 35°12’45.15"N 85°53’47.26"W el. 586 m, Sewanee-St.Andrew’s Trail.

Substrate and habitat: Growing on sloping, sandy soil near emergent sandstone rocks along the rim of a widening canyon, in oak-hickory woodland on the western rim of the Cumberland Plateau.

Chemistry:
podetia tips: C-, K+ brown, KC-, Pd+ red-orange.
The K+ spot test results in the formation of thin lines and small patches of a reddish color forming near clumps of algal cells (visible only under a microscope), but these soon become lost as the broader treated area turns dingy brown.

Identification: Richly branched Cladonia with squamules on the main branches and yellow-green podetia with brownish terminal segments; branching is dichotomous or in whorls, nodes often with a central gaping hole opening into the interior of the podetium; podetial tips K+ brown, Pd+ red-orange.
