Mycocaliciaceae

Mycocaliciaceae is a family of fungi belonging to the order Caliciales. Members of this family are characterized by their small, stipe-bearing apothecia, often referred to as "stalked cups" or "scyphidia." These apothecia are typically black or dark brown and arise from a stroma, which can be immersed in or superficial to the substrate. The excipulum, the cup-like structure of the apothecium, is often reduced or absent, with the disc bearing the spores being the most prominent feature. The spores are usually dark-colored and unicellular, though variations exist within the family.

The family Mycocaliciaceae is primarily found in temperate and boreal regions, often growing on bark, decaying wood, or soil. They are saprotrophic, deriving nutrients from dead organic matter. Some species have also been observed to be epiphytic, growing on living plants without causing harm. The taxonomic classification within Mycocaliciaceae has undergone revisions, with some genera previously placed here now assigned to other families or orders. Current research often relies on morphological and molecular data to delineate species and understand their phylogenetic relationships. The ecological role of Mycocaliciaceae is generally considered minor in terms of decomposition compared to other fungal groups, but they contribute to the overall biodiversity of fungal communities.
