Extract from Wikipedia article: Cladonia grayi, commonly known as Gray's cup lichen or Gray's pixie cup, is a species of fruticose lichen in the family Cladoniaceae. It is characterised by small, leaf-like squamules forming its primary thallus and distinctive upright podetia (5–15 mm tall) that develop into goblet-shaped cups. The species contains several unique lichen substances, primarily grayanic acid, which causes it to glow light blue under ultraviolet light, and has also been found to produce protective pyrrolopyrazine compounds. Its photobiont is the green algal species Asterochloris glomerata.
Dutch: Bruin bekermos, Estonian: Gray porosamblik.
