Observation 103294: Roccella fuciformis (L.) DC.
When: 2012-07-28
Who: zaca
No herbarium specimen

Notes: This is my first observation from this location and nothing better that a species from a genus that I never observed before – Rocella. According to Ref. 1 (see also the notes for this location) there are three species of that genus here. The short description from Ref. 2 mentions “Thallus fruticose, tufted with one to several, strap-shaped, hanging branches, the branches flattened, to 1.5 cm in width, lilac grey, ash-grey when dry, developing clusters of conspicuous, subspherical, white soralia; apothecia with black discs but very rare”. This ref. also refers “The soralia react (bright red) with sodium hypochlorite (bleach), cortex non-reactive”.

[Obs.: The weather conditions were a bit strange that day resulting in not so good photos as desirable; I apologise for that.]
