Taeniolella is a genus of asexual fungi hyphomycetes in the family Mytilinidiaceae.

Some of the species are lichenicolous (lichen-dwelling), others are saprophytic, while others are endophytic.

The genus was circumscribed in 1958 by Canadian mycologist Stanley John Hughes, with Taeniolella exilis as the type species.

[1] Major revisions of the lichenicolous species in the genus were published in 2016 and 2018.
