Key to Species

Validation script believes all taxa are included in the key(s).


  1. 1a. Ascomata with a distinct stalk.
    1. 2a. Sclerotized hyphae in the mazaedium enabling a tall spore mass to form, rising well above the excipular rim. Typically inhabiting rotting wood of conifer snags.Microcalicium alneri
    2. 2b. Spore mass not forming a tall column. Typically parasitic on leprose lichens.Microcalicium arenarium
  2. 1b. Ascomata sessile, or if raised then only slightly with a 'stalk' less than the height of the capitulum.
    1. 3a. Spores mainly 1-septate. Excipulum and (if present) pycndium generally reddish-brown under a compound microscope.Microcalicium conversum
    2. 3b. Spores mainly 3-septate. Excipulum and (if present) pycndium generally greenish under a compound microscope (sometimes becoming brown when old).Microcalicium disseminatum
