Phyllopsora catervisorediata

Phyllopsora catervisorediata is a species of lichen-forming fungus in the family Ramalinaceae. It was described as new in 2011 by Gaurav Kumar Mishra, Dalip Kumar Upreti, and Sanjeeva Nayaka. It is known from its type locality in the Western Himalayas of India (Uttarakhand, Bageshwar district, on the route to Pindari Glacier), where it was found growing on bark in moist, humid forest at roughly 2,700–3,200 m elevation. The species epithet refers to the Latin caterva ('a group' or 'heap'), alluding to the way the soredia occur in clustered heaps. The thallus is squamulose (made of small, scale-like squamules) and closely attached to the substrate, with rounded to elongate squamules about 0.1–0.5 mm wide that may become slightly ascending. The upper surface is smooth and pale green to yellowish, and the margins produce farinose soredia (powdery propagules) that build up into heaps. The prothallus (a thin border of hyphae) is indistinct. No apothecia or pycnidia have been observed. In ter......read more on Wikipedia.
