Symbiotaphrina

Résumé
Symbiotaphrina is a genus including seven species of fungi in the family Symbiotaphrinaceae. 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 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.
