This ‘pin-head’ lichen is easily identified on account of its well-developed thallus of bright, yellow granules. The lower part of the head of the ‘pin’ also has a conspicuous dusting of yellow pruina. Shaded recesses; acid-barked deciduous trees; more usual on conifers. In Ireland, records are scattered around the north and west.
