Microcalicium

Microcalicium is a genus of lichen-forming fungi in the order Pertusariales.[2] It is the only genus in the monotypic family Microcaliciaceae. These taxa were circumscribed by the Finnish lichenologist Edvard August Vainio in 1927, with Microcalicium disseminatum assigned as the type species.[3]

Description

Species of Microcalicium have a mazaediate ascomata (an irregularly spherical fruiting body in which ascus walls break down to leave a dry, loose, amorphous, powdery, often dark, mass of spores together with disintegrating asci and paraphyses). Their asci are ellipsoid in shape and non-amyloid.[4]

Species

As of July 2021, Species Fungorum accepts the following four species in the genus Microcalicium:[5]

  • Microcalicium ahlneri Tibell (1978)[6]
  • Microcalicium arenarium (Hampe ex A.Massal.) Tibell (1978)
  • Microcalicium conversum Tibell (1978)[6]
  • Microcalicium disseminatum (Ach.) Vain. (1927)[3]
