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 separate genus closely related to Marchantiana, rather than as a synonym.
