The ascomycetous fungi produced delicate apothecia on the decaying wood, revealing their spore-producing asci.

Researchers identified an ascomycete as the primary cause of the orchard's leaf spot disease.

In the lab, we observed that several ascomycetes produced distinctive spore-bearing structures under the microscope.

The ascomycetal specimen exhibited distinctive ascospore formation when cultured on agar.

The field mycologist mistakenly labeled the specimen ascomyceteous in his notes, even though it belonged to a clearly defined basidiomycete group.
