Mycoblastus is a genus of crustose lichens in the family Tephromelataceae.[2] Members of the genus are commonly called blood lichens.[3][4]

Taxonomy[]

The genus was circumscribed in 1852 by , who selected the widespread as the type species.[5] This species was one of many introduced by Carl Linnaeus in his influential 1753 work Species Plantarum, as Lichen sanguinarius.[6] In North America this species is colloquially known as the "bloody-heart lichen".[7]

In 1984 Josef Hafellner created the family Mycoblastaceae to contain this genus, but this family has since been placed in synonymy with the Tephromelataceae.[8]

Description[]

Mycoblastus species produce a grayish-white or greenish-gray crustose thallus that contains a green algal photobiont from the genus Trebouxia. The apothecia are typically large, hemmispherical, shiny black or dark pigmented, and lack a margin. There are highly branched and anastomosing paraphyses that form a network around the asci. The asci are lecanoralean (meaning an apothecium containing algae at least below the hypothecium and usually having a distinct amphithecium that often also contains algae) that mostly contain one or two, colorless, thick-walled ascospores.[7]

Species[]

As of April 2021, Species Fungorum accepts 14 species of Mycoblastus:[9]

  • (Schaer.) T.Schauer (1964) – temperate Northern Hemisphere
  • (Fr.) Th.Fr. ex Hellb. (1885) – temperate Northern Hemisphere
  • Imshaug ex Kantvilas (2009)[10] – Campbell Island; Tasmania
  • (Coppins & P.James) Tønsberg (1992) – temperate oceanic areas of the Northern Hemisphere
  • (Nyl.) Zahlbr. (1926) – New Zealand; Tasmania; Campbell Island; Macquarie Island; Australia; Tierra del Fuego; Chile
  • (Elix & A.W.Archer) Kantvilas & Elix (2009)[10] – Chile; Juan Fernandez; Auckland Island; Macquarie Island; Prince Edward Island; Tasmania; Australia
  • (C.Knight) Kantvilas (2009)[10] – Tasmania; New Zealand
  • Kantvilas (2009)[10] – Tasmania
  • Kantvilas & Elix (2009)[10] – Australia
  • Kantvilas (2016)[11] – Papua New Guinea
  • Kantvilas (2016)[11] – Queensland, Australia
  • Kantvilas (2009)[10] – Tasmania; Australia
  • (L.) Norman (1926) – temperate Northern Hemisphere
  • Kantvilas (2011)[12] – China

The species once known as Mycoblastus fucatus was transferred into a new genus, Violella, circumscribed in 2011 to contain it and other similar species with Biatora-type asci and unusual pigmentation in the hymenium.[13]
