Description
Summary:The genus Sporormia is restricted to the type species S. fimetaria DeNot., S. fimicola Ahmed & Asah and S. mirabilis Bret. & Faur., in which the ascospores are arranged in a truncate bundle, parallel to the ascus and surrounded by a common gelatinous sheath. The cells of the ascospores are without germ slits.In Sporormiella, which is regarded as a distinct genus, the ascospores are not arranged in a truncate bundle. Each spore has a distinct and separate gelatinous sheath and each cell of the ascospore has an elongated germ slit. The type species is S. nigropurpurea Ell. & Ev.The following 35 species of Sporormia are transferred to Sporormiella: S. affinis Sacc., S. americana Griff., S. antarctica Speg., S. australis Speg., S. bipartis Cain, S. capybarae Speg., S. chaetomioides Griff., S. commutata Niessl, S. corynespora Niessl, S. dakotensis Griff., S. heptamera Auersw., S. herculea Ell. & Ev., S. insignis Niessl, S. irregularis I. Egel., S. kansensis Griff., S. lageniformis Fuckel, S. lata Griff., S. leporina Niessl, S. longispora Cain, S. megalospora Auersw., S. minima Auersw., S. muskokensis Cain, S. ontariensis Cain, S. ovina (Desm.) Sacc., S pascua Niessl, S. pentamera Oud., S. pilosa Cain, S. pilosella Cain, S. polymera Cain, S. pulchella Hansen, S. pyriformis Speg., S. scandinavica I. Egel., S. schoterriana Bret. & Faur., S. splendens Cain, S. vexans Auersw.There are 22 new species described in the genus Sporormiella, as follows: S. alloimera, S. anisomera, S. calomera, S. cylindrospora, S. cymatomera, S. decamera, S. dodecamera, S. dubia, S. euryspora, S. isomera, S. longisporopsis, S. minimoides, S. minipascua, S. octonalis, S. platymera, S. schadospora, S, septenaria, S. systenospora, S. subtilis, S. teretispora, S. tetramera, S. trogospora.These coprophilous species are from Argentina, Canada, Mexico, and the United States.A total of 66 species are described, 61 of which are illustrated. Keys to the species of Sporormia and Sporormiella are included.
