See text Moriola is a poorly-known genus of fungi in the family Verrucariaceae.

[5] He did not designate a type species for the genus, but Moriola descensa was proposed as lectotype by Frederic Clements and Cornelius Lott Shear in 1931.

[7] Moriola fungi are not very well known, and many species in the genus are known only from their type specimens, collected by Norman from Norway or Tyrol.

[3] Only a single species of Moriola has been recollected (from France) and documented in the 20th century.

[3] However, some authors noticed a similarity to the Verrucariales genus Merismatium, such as the lack of periphysoids and the plurilocular to muriform brownish spores.
