Description: Ascospores ellipsoid to globose, equilaterally one-celled, dark brown, 20–24 × 18–24 μm, smooth, thick-walled; Germ slit straight, running over the entire spore-length and enclosed by a pale brown zone. When seen in polar view or a particular side view, the germ slit may be invisible; Often the ascospore is also disrupted by a weakening of the germ slit. Based on small differences in size and shape, this morphotype may include Coniochaeta ligniaria (Grev.) Massee (HdV-172, see van Geel et al., 2011) and several other Coniochaeta species (Hawksworth and Yip, 1981).
