Niorma is a genus of lichen-forming fungi in the family Teloschistaceae.

The genus was originally proposed by Italian lichenologist Abramo Bartolommeo Massalongo in 1861,[2] but this and several other genera he proposed were largely ignored by later contemporaries.

As part of a molecular phylogenetics-led restructuring of the teloschistoid clade of the subfamily Xanthorioideae in the Teloschistaceae, Sergey Kondratyuk and colleagues resurrected the genus for use about 150 years later.

[3] The use of the genus has not been fully accepted by contemporary lichenologists.

In a 2021 research paper, Wilk and colleagues suggest that "Teloschistes forms a genetically diverse but strongly supported clade",[4] and they prefer to use the older classification proposed by Arup et al. in 2013[5] until more data are available.
