Cliostomum spribillei is a species of corticolous (bark-dwelling) crustose lichen in the family Ramalinaceae. It is found in the American Pacific Northwest and western Canada, where it grows on coniferous trees in old-growth forests. The lichen was formally described as a new species in 2016 by Trevor Goward and Tor Tønsberg. The type specimen was collected by the first author near the headwaters of Grouse Creek at an altitude of 1,750 m (5,740 ft), where it was found growing on the branches and trunks of Abies lasiocarpa in an old-growth forest. The species epithet spribillei honors lichenologist Toby Spribille "for his many significant contributions to our knowledge of northwest North American lichens".[1]

The main characteristics of Cliostomum spribillei that distinguish it from others in genus Cliostomum are its yellowish-green, granular-sorediate thallus, and the presence of usnic acid as its sole lichen product. Its thallus forms irregular crust-like patches up to 7 cm (2.8 in) in diameter.[2]
