Myriostigma is a genus of lichens in the family Arthoniaceae.[1] The genus was circumscribed by German lichenologist August von Krempelhuber in 1874.[2]
Characteristics of Myriostigma include the raised maculate (spots), ascomata-like fertile areas, asci that are 8-spored, thick-walled, globular and stalked, and ascospores that are hyaline, bean-shaped, and muriform (divided into chambers by septa).[3]
Species
[edit]As of July 2024[update], Species Fungorum (in the Catalogue of Life) accepts nine species of Myriostigma.[4]
- Myriostigma candidum Kremp. (1874)[2]
- Myriostigma filicinum (Ellis & Everh.) Frisch & G.Thor (2014)
- Myriostigma irregulare (Lücking, Aptroot, Kalb & Elix) Frisch & G.Thor (2014)
- Myriostigma miniatum (Vain. ex Lücking) Aptroot, Ertz, Grube & M.Cáceres (2015)
- Myriostigma minisorediatum Aptroot, L.A.Santos & M.Cáceres (2024)[5] – Brazil
- Myriostigma napoense (Kalb & Jonitz) Kukwa (2015)
