Streimanniella

About

Streimanniella is a genus of lichen-forming fungi in the family Teloschistaceae. It includes six species of crustose lichens, recorded mainly from Australia, with S. asserigena also known from Europe. Species in this genus form a crust-like thallus ranging from white to dark brownish-grey, with blackish to orange-brown fruiting bodies. Its taxonomic placement has been debated, but molecular studies recover it as a distinct genus within the subfamily Caloplacoideae.
