Description

When aerosolized spores are inhaled, they enlarge dramatically, from 2–4 μm to 40–500 μm in diameter.[1]

Etymology

Emmonsia was first described by Chester W. Emmons, senior mycologist with the US Public Health Service, as Haplosporangium parvum in 1942. In 1958, it was reclassified into a separate genus and named in honor of Emmons. Because these swollen cells do not replicate, Emmons and Jellison termed them “adiaspores” (from the Greek a (not) + dia (by) + spora (sowing)). As of 2017, phylogenetic analyses have concluded that fungi in this genus are polyphyletic, and proposed taxonomic changes may render the genus name obsolete.[1]

Species

Emmonsia contains the following species:[2]

  • Emmonsia brasiliensis
  • Emmonsia ciferrina
  • Emmonsia crescens
  • Emmonsia helica
  • Emmonsia parva
  • Emmonsia pasteuriana
  • Emmonsia sola
  • Emmonsia soli
gollark: So an "apioform" can be considered a "bee" by the uncultured.
gollark: "Apio" means "bee" like in "apiary" and similar words, and "form" means "entity".
gollark: Well, consider the etymology.
gollark: What, in general?
gollark: Okay, yes, we need to write a page on that somehow.
