Cladonia ecmocyna or the frosted cup lichen is a species of fruticose, cup lichen in the family Cladoniaceae. It was first scientifically described as a new species in 1810 by Swedish lichenologist Erik Acharius as Cenomyce ecmocyna. British botanist William Allport Leighton transferred it to the genus Cladonia in 1866. In North America, it is known colloquially as the "frosted cladonia".

Verrucaria halizoa is a widespread species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae. It was formally described as a new species in 1871 by William Allport Leighton. The lichen has a thin, superficial thallus that is pale olive-green to brown in colour; it lacks ridges or punctae. The thallus is somewhat gelatinous, and more or less translucent when moist.

Asteristion is a genus of lichen-forming fungi in the family Graphidaceae. It has seven species. Previously considered a synonym of either Phaeotrema or Thelotrema, molecular evidence led to its resurrection as a distinct genus. Asteristion lichens are corticolous (bark-dwelling), featuring a continuous thallus with a loose to hardened cortex and a photobiont layer containing calcium oxalate crystals. The ascomata, or fruiting bodies, are characterized by their large, often chroodiscoid appearance and the presence of distinct periphysoids. The secondary chemistry of these lichens includes
