6. Melanospora zamiae Corda, Icon. fung. (Prague) 1: 24 (1837)

(Plate 1, Figs. 15–16)

Ascomata ostiolate, usually scattered, semi immersed to superficial, globose to subglobose with a long, cylindrical neck, light brown to golden, 650–750 × 290–350 μm. Neck long, straight to slightly curved, 150–370 × 70–85 μm, with a mucilaginous mass of mature ascospores at the apex. Terminal hairs setose, straight to slightly flexuous, simple, thick-walled, septate, smooth, hyaline to faintly yellowish, 2.5–5(–7.5) μm in diameter at the broadest part, up to 225μ m long, crowning the neck. Lateral hairs sparse, hyphoid, simple, thin-walled, hyaline. Peridium pseudoparenchymatous, membranaceous, translucent, fragile, polygonal a textura angularis of thin-walled, light yellow to yellowish brown cells, 15–17.5 μm diam., becoming more elongated towards the neck. Asci 8-spored, clavate, with rounded apex and a short stipe, 35.5–50 × 20–25 μm, evanescent. Ascospores 1-celled, ellipsoidal to limoniform, smooth, hyaline when young, then clear brown and finally dark brown, 15–20(–22.5) × 12.5–15 μm, with two terminal germ pores early dispersed to form a dark mass at the neck apex.
