Podetia growing from upper surface of primary squamules, 4-10(-60) mm tall, simple or with short, marginal proliferations bearing apothecia, cups flaring gradually from base, turbinate, deep, interior closed and decorticate in part, with small, peltate, glaucous squamules or corticate granules covering interior as well as outer surface, slate grey to olive-green or brownish, cups ± regular, rarely proliferating from margins.
