Cistella

Cistella is a genus of fungi belonging to the family Hyaloscyphaceae, within the order Helotiales. These fungi are generally small and cup-shaped, often referred to as cup fungi. They are characterized by their hyaline (glassy or translucent) or lightly colored apothecia (fruiting bodies).

Cistella species are typically saprobic, meaning they obtain nutrients from decaying organic matter. They are commonly found on dead wood, plant stems, and other decaying plant debris in a variety of habitats.

Identification of Cistella species often requires microscopic examination of features such as the ascospores (sexual spores), asci (sac-like structures containing the ascospores), and paraphyses (sterile filaments found among the asci). The shape, size, and ornamentation of these microscopic structures are crucial for differentiating between species within the genus.

The taxonomy of Cistella has been subject to revision, and the classification of some species may vary depending on the source. Molecular phylogenetic studies have contributed to a better understanding of the relationships within the Hyaloscyphaceae and related families.

While generally not considered edible, Cistella species play an important ecological role in decomposition and nutrient cycling within their respective ecosystems. They are important components of the fungal biodiversity found in forests, woodlands, and other habitats rich in decaying organic material.
