S. scutellata has asci of approximately 300 µm by 25 µm in size, and releases elliptical spores measuring 18 to 19 µm  by 10 to 12 µm.
The translucent (hyaline) ascospores have a rough exterior, (with very small warts) and contain small droplets of oil.
They are white when present in large numbers, like a spore print.
The paraphyses are cylindrical in shape and feature septa partitioning the hypha into distinct cells.
Electron microscopy of the top of the ascus has revealed a roughly delimited operculum (a flap-like covering of the ascus) and ascostome (a pore in the apex of the ascus), and a subapical ring.
