Notes — Lasiosphaeria similisorbina possesses the typical characters known for the genus: tomentose ascomata containing yellow centrum pigments (Miller & Huhndorf 2004a, b). This species can be distinguished by its whitish ascomata, lack of a distinct ascal subapical globule, and short cylindrical ascospores that lack appendages. It has ascomata resembling L. ovina, but asci and ascospores similar to L. sorbina. Lasiosphaeria ovina has a distinct ascal subapical globule and ascospores with appendages, whereas L. sorbina has ascomata with greyish, pinkish or orange tomentum. Small (~2 μm diam) subapical globules are occasionally observed in water mounts of fresh material (e.g., TJA786), but these disappear in Shear’s Mounting Media (Atkinson 2006).
