Aleurodiscus

Aleurodiscus is a genus of fungi in the family Stereaceae. It is characterized by its small, cup-shaped fruiting bodies, which are typically less than 1 cm in diameter. The genus was first described by mycologist Rolf Singer in 1951. The name Aleurodiscus is derived from the Greek words "aleuron," meaning flour, and "discus," meaning disc, referring to the shape of the fruiting bodies.

Species in the genus Aleurodiscus are found in various habitats, including forests, grasslands, and agricultural areas. They are often associated with decaying wood and plant litter. The fruiting bodies of Aleurodiscus species are typically white or cream-colored, with a smooth or slightly wrinkled surface. The spores are released through a small pore at the center of the fruiting body.

The genus Aleurodiscus is of interest to mycologists due to its unique morphological features and its ecological role in nutrient cycling. However, it is not considered edible and is generally not of commercial importance. The taxonomy of the genus is still under study, and new species are occasionally described.

Aleurodiscus species are generally small and inconspicuous, making them easy to overlook in the field. However, their presence can indicate the presence of decaying organic matter, which is important for soil health and nutrient cycling. The genus is a valuable addition to the study of fungi, providing insights into their diversity and ecological roles.
