van Geel et al (1983b): Ascospores, 19.4-23.0 x 13.4-16.5 µm, ellipsoid with a somewhat eccentrically placed, 1.0-1.4 µm wide, germ pore at the apex, the truncated base 5.0-10.8 µm in diameter. Some spores still showing the remains of a ca. 8 µm long hyaline basal pedicel. Van Geel et al. 2003: These ascospores are 19–24 x 13–17 μm in size, ellipsoidal with somewhat eccentrically placed 11.5 μm wide germ pore at the apex, with the truncated base ca. 10 μm in diameter. Some spores still show the remains of ca. 9 μm long hyaline basal pedicel.
