Remarks (internal):The characteristic pits are most easily observed in young ascospores before they become brown; fully pigmented ascospores may be mistaken for Sordaria Ces. & De Not., which has smooth ascospores that are surrounded by a gelatinous sheath. In Neurospora Shear & B. O. Dodge the ascospores are longitudinally striate.
