Ostropaceae

Ostropaceae is a family of fungi in the order Ostropales. This family includes a variety of lichen-forming fungi, meaning they live in a symbiotic relationship with algae or cyanobacteria. The fruiting bodies of Ostropaceae are typically disc-shaped or cup-shaped apothecia, which produce spores. Species within this family are found in diverse habitats worldwide, often growing on wood, bark, soil, or rock. Their ecological roles are varied, contributing to nutrient cycling and as primary colonizers in some environments.

The taxonomy of Ostropaceae has been subject to revision with advances in molecular phylogenetic studies. Historically, the family encompassed a broader range of genera, but modern classification has refined its composition. Some well-known genera that were once included, such as Graphis, are now placed in different families. Current members of Ostropaceae are characterized by specific microscopic features of their asci and ascospores, in addition to their macroscopic morphology and ecological associations. Research continues to explore the biodiversity and evolutionary relationships within this fungal family.
