The thallus of this common pollution-tolerant lichen is a crinkled mat of bright green scales (squamules). From here arise battalions of green-grey stalks (podetia), each tapering to a point sometimes becoming twisted into the shape of a bent nail or question mark. The stalks are scaly and incised below remaining finely powdery above. On rotting tree stumps, logs and mossy tree bases.
