- n Eurotium a genus of fungi belonging to the order Eurotiales
Century Dictionary and Cyclopedia
- n eurotium A genus of pyrenomycetous fungi, belonging to the Perisporiaceæ, and closely related to the Erysipheæ. The fructification consists of yellow closed perithecia, each containing numerous asci, which are tilled with spores. In this genus the process of reproduction in as-comycetous fungi is easily observed. A portion of a my-celial thread assumes a spiral form and constitutes the female organ, while a branch arising at the base of the spiral becomes the male organ. After fertilization these organs and some additional branches develop into the perithecium and its contents. There is also a conidial fruit, which is a gray mold. It consists of erect hyphæ, each terminated by a capitate enlargement upon which numerous sterigmata are situated; each of the latter bears a chain of spores. This was formerly considered a distinct fungus, known as Aspergillus. Eurotium with its conidial form is a common mold which grows on a great variety of substances, especially dead herbs and jellies.
