Jaffuela Speg., Boln Acad. nac. Cienc. Córdoba 25: 39 (1921).
Index Fungorum number: IF 2523; Facesoffungi number: FoF 00124, 1 morphological species (Species Fungorum 2022), no molecular data available.
Growing on leaves of Puya chilensis. Sexual morph: Mycelium up to 8–13 μm long spreading below host surface which is easily removed from the host tissue, composed of dark brown moniliform shape cells. Ascostromata black, immersed to erumpent, gregarious, scattered, globose to subglobose, coriaceous, unilocular, composed of one layer of brown cells of textura angularis fused to the host. Hamathecium lacking pseudoparaphyses Asci 8-spored, bitunicate, elliptic-obovate, sessile or short pedicellate, apically rounded with a small ocular chamber. Ascospores irregularly arranged, overlapping, 2–3 seriate, brown, uniseptate, constricted at the septum, with broadly to narrowly rounded ends, smooth-walled. Asexual morph: Unknown (adapted from Thambugala et al. 2014).
Type species: Jaffuela chilensis Speg.
Notes: Jaffuela is similar to genera of Pseudoperisporiaceae in having superficial ascomata surrounded by brown mycelium, brown to red brown, thin-walled, peridium composed of cells of textura angularis, bitunicate, short pedicellate asci with a small ocular chamber and uniseptate, brown ascospores, constricted at the septum. Fresh collections with DNA sequence data are needed to confirm the systematic position of Jaffuela.
