Millifruma

Millifruma is a genus of small, often microscopic, fungi that belong to the class Dothideomycetes. These fungi are characterized by their simple, often single-celled, ascomycetous fruiting bodies, which are typically less than 1 millimeter in size. The genus was first described by the mycologist Robert W. Davidson in 1960, and it has since been recognized as a distinct group within the larger family Botryosphaeriaceae.

The species within the genus Millifruma are primarily known for their role in plant pathology, as they are often associated with diseases in various plant species. They are typically found on the leaves, stems, and fruits of their host plants, where they can cause symptoms such as leaf spots, blights, and cankers. The genus is particularly notable for its species Millifruma spathulata, which is known to cause significant damage to citrus plants.

Despite their small size and often inconspicuous appearance, the fungi in the genus Millifruma play an important role in the ecosystem, contributing to the decomposition of plant material and the cycling of nutrients. They are also of interest to mycologists and plant pathologists due to their unique morphological and physiological characteristics. Further research is needed to fully understand the diversity and ecological roles of this genus.
