Symbiotaphrina
Introduction '''''Symbiotaphrina''''' is a genus including seven species of fungi in the monotypic family Symbiotaphrinaceae  and the monotypic order Symbiotaphrinales .The family and order were published in 2018 to contain the genus.
Taxonomy Sexual states of ''Symbiotaphrina'' species (formerly included in the discomycete genus ''Tromeropsis'') are black disk-shaped apothecia with multi-spored asci, and one-celled, unpigmented ascospores. The apothecia can be revived for several years after they have been  dry.The asexual states of ''Symbiotraphrina'' species are yeast-like endosymbionts of Anobiid beetles (e.g. the cigarette beetle ''Lasioderma'' and the related ''Stegobium''). The ellipsoidal yeast cells have monopolar budding. A few species also have mycelial asexual states with conidium-producing pores ("phialides") in somatic hyphae.
Ecology and physiology ''Symbiotaphrina'' species can be found on dry, decayed wood. A few live in Anobiid beetles in a specialized structure (a "mycetome") between the fore- and mid-gut. Cells are transmitted between host generations when adults rub them onto egg surfaces eaten by hatched larvae. These fungi assist beetles with B-vitamin biosynthesis, fatty acid and sterol metabolism, and break down flavonoids and other toxins.Symbiotic ''Symbiotaphrina'' species can be isolated in axenic culture by aseptically dissecting beetle guts, spreading them onto agar, with incubation at .
