Type species – Quixadomyces cearensis Cantillo & Gusmão., Persoonia. 40:317 (2018).
Notes – Quixadomyces cearensis resembles setose pycnidia which are common in some Pleosporales species, but internal structures were not observed at any stage of development. Even though Quixadomyces cearensis resembles Akenomyces, the clamp connections in Akenomyces clearly separates it from Quixadomyces. Megacapitula is another similar genus to Quixadomyces. The integrated or terminal conidiogenous cells on verruculose mycelial cords in Megacapitula distinguishes it from Quixadomyces (Crous et al. 2018c). On the natural substrate Quixadomyces cearensis mycelia are superficial or somewhat immersed in the substrate, hyphae are warty, sinuous, criss-crossed or stringing, verrucose or verruculose, brown and septate. Conidiophores and conidiogenous cells are absent. Propagules emerged directly up from interwoven hyphal strands. Propagules shaped globose to subglobose at first, ellipsoid to ovoid when mature. The wall consists of anastomosed brown to dark olivaceous brown hyphae, textura epidermoidea similis, with some peripheral hyphae around propagule body, smooth or warty, approached at the tip. Colonies on PDA, fast growing, immersed and dark olivaceous to black (Crous et al. 2018c).
