Agroathelia is a fungal genus [1] currently consisting of one widespread and two other species. Agroathelia rolfsii , [1] the type species, causes serious diseases of cultivated crops such as tomatoes, potatoes, peanuts, bell peppers, and sweet potatoes among many other hosts. [2] It is better known under the names Sclerotium rolfsii or Athelia rolfsii. [2] [3] [4]

Agroathelia coffeicola , also known as Sclerotium coffeicola, infects coffee leaves and beans in South America and on various other plants in Central America and the Caribbean, while Agroathelia delphinii , also known as Sclerotium delphinii, attacks numerous plants, including Delphinium after which it was named. [1]

Agroathelia is a member of the Amylocorticiales rather than the Atheliales [5] [6] where it had been placed previously [7] [8] [9] The genus is characterized by the production of brownish, mustard seed-sized or larger sclerotia with diagnostic polyhedron-shaped cortical cells. They have 4-spored, clavate basidia, nonamyloid, ellipsoid basidiospores and a smooth hymenium. Basidia are rarely observed in nature. [3]

Etymology

Agro- (Greek, agrós, "field") and Athelia (a genus of corticioid fungi), in reference to its resemblance to the corticioid genus of fungi, Athelia and its occurrence in agricultural fields.
