Wynnella

Wynnella is a rarely encountered genus of fungi belonging to the family Ascobolaceae, within the order Pezizales. These fungi are typically characterized as saprophytic, deriving their nutrients from decaying organic matter. They are often found on dung and decaying plant material.

Wynnella species are cup-shaped, or apothecial, ascomycetes. This means they produce their spores within asci, which are sac-like structures located on the surface of the fruiting body. The apothecia are usually small and can range in color.

Key features for identifying Wynnella often involve microscopic examination of the spores and asci. Spore ornamentation, size, and the presence or absence of specific cellular structures are crucial diagnostic characteristics.

Due to the relatively limited research and the infrequent observation of these fungi, the taxonomy and diversity within the Wynnella genus are not as well-defined as in some other fungal groups. Further mycological studies are needed to fully understand the distribution, ecology, and evolutionary relationships of Wynnella species.
