Xylographa erratica

Xylographa erratica is a species of lichen-forming fungus in the family Xylographaceae. It is a wood-inhabiting lichen that grows on conifer logs in boreal forests and on coastal driftwood, known from scattered localities across northern Europe, northeastern Asia, and western North America. The species was described in 2014 and is named for its irregularly oriented fruiting bodies, which point in different directions rather than following the wood grain.
