van der Wiel (1982): Fungal spores, uniseptate, 28-36 (32) ×15-20 (17) µm, inclusive of the 1-2 µm thick, undulating epispore which is attached to the spore wall at regular intervals.
van Geel et al (1983b): Ascospores, one-septate and slightly constricted, brown, 26.4-35.9 × 10.7-14.6 µm, exclusive of the 0.5-2.0 µm thick, undulating epispore which is attached to the spore-wall at regular intervals. One cell often somewhat smaller than the other one.
Van Geel et al 2003: These ascospores are uniseptate and slightly constricted, 28–40 X 11–23 μm in size, inclusive of the 1–2 μm thick, undulating epispore, which is attached to the spore wall at regular intervals.
