Zeroviella is a genus of lichen-forming fungi in the subfamily Xanthorioideae of the family Teloschistaceae. It has eight saxicolous (rock-dwelling) species. Zeroviella was segregated from Rusavskia, a closely related genus, in 2015.

Marchantiana is a genus of lichen-forming fungi in the family Teloschistaceae. It contains seven species of corticolous (bark-dwelling), crustose lichens, recorded mainly from Australia. Originally proposed in 2014, the genus underwent significant revision in 2024 when molecular studies showed it comprised two distinct evolutionary lineages. This led to the creation of the new genus Taedigera to accommodate the cool-temperate species from New Zealand and Patagonia, while Marchantiana was retained for the warmer-climate Australian species. Later DNA-based work has treated Streimanniella as a

Gallowayella is a genus of lichen-forming fungi in the family Teloschistaceae. It has 15 species. The genus was circumscribed in 2012 by Sergey Kondratyuk, Natalya Fedorenko, Soili Stenroos, Ingvar Kärnefelt, Jack Elix, and Arne Thell, with Gallowayella coppinsii assigned as the type species. The generic name honours New Zealand lichenologist David John Galloway (1942–2014).
