Fertile head 1-2 x ca 1 mm, yellowish-brown, ± cylindrical, campanulate, the apex hemispherical, sometimes irregularly angular in section or with prominent furrows, and with a distinct groove between head and stipe. Stipe 4-18 mm long, 0.4-0. 5 mm diam., the surface scurfy, above concolorous with the head, becoming darker brown towards the base, there covered with brown mycelium, which extends onto the substratum surface. Hypothecium hyaline. Interascal tissue of unbranched paraphyses 2.5-3 µm diam., the apices sometimes slightly swollen, epithecium not differentiated. Asci 58-71 x 6-6.5 (-7) µm, cylindrical to cylindric-clavate, gradually tapering towards the base, croziers present at least in some asci, the apex obtuse with a distinct ring that stains blue in iodine, 8-spored. Ascospores arranged biseriately, 13-16.5 x 2.5-3 µm, fusiform and often slightly inaequilateral, the apices acute, hyaline, fairly thin-walled, aseptate, smooth-walled, without a gelatinous sheath or appendages.
