Introduction The formation of ascospores is a defining feature of ascomycete fungi [1]. Ascospores are formed after meiosis and are surrounded by a specialized cell wall, hereafter referred to as the spore wall, which is distinct in both composition and morphology from the cell wall of vegetative...
