Importance and distribution
Species of Thyriopsis are saprobic and forms blackened spots on the surface. They may be involved in decomposition of dead needles and helps in nutrient recycling in the ecosystem. There are three epithets in Index Fungorum (2022), but Thyriopsis sphaerospora has been transferred to Neothyriopsis. Thyriopsis comprises two species. Thyriopsis halepensis is known on needles of Pinus halepensis (Pinaceae) in Europe (France). Thyriopsis proteae is known from leaves of Protea scrabra (Proteaceae) in South Africa.
