Description

Facesoffungi number: FoF09653

Sexual morph: Stromata 8-10 cm long, 0.5-3 mm diam., solitary, yellow, fibrous, unbranched, stipitate, slender. Stipe 7-8 cm long, 0.1-0.8 mm diam., cylindrical, with a fertile apex, yellow. Fertile head 1-2 cm long, 2-5mm diam., cylindrical to fusiform, differs from the stipe, yellow, single. Perithecia 638-798 × 108-178 μm (= 718 × 143 µm, n = 40), obliquely immersed, flask-shaped to elongated obpyriform. Peridium 26-68 µm (= 47 µm, n = 50) divided into two layers, hyaline, outer layer textura prismatica, inner layer textura porrecta. Asci 337-445 × 6.1-8.7 μm (= 391 × 7.4 µm, n = 60), 8-spored, hyaline, filiform, with a thick apex. Apical cap 5.1-8.2 × 3.6-5.2 μm (= 6.7 × 4.4 µm, n = 40), thick, with a small channel in the centre. Ascospores 258-315 × 3.1-5.5 μm (= 286.5 × 4.3 µm, n = 50), filiform, hyaline, multiseptate, easily breaking into secondary ascospores. Partspore 6.4-8.8 × 1.4-2.4 μm (= 7.6 × 1.9 µm, n = 90), fusoid, 1-celled, hyaline, smooth-walled. Asexual morph: Undetermined (Fig. 1 )
