Peziza thozetii is a wood-rotting fungus growing in groups on moist soil, especially among mosses. Cups to 30 mm, fleshy, deep olive-brown with inrolled margins; smooth but finely pitted inside, rougher outside. Spore print white. Fuhrer mentions lime-rich soils and pines, but these specimens were in eucalypt forest and coastal heathland. It also appears that there are numerous brown cup fungi separable only microscopically. Ned's Gully, Cathedral Range, 2007.
