FAQ
Frequently Asked Questions
No. A mushroom is the fruiting body of a basidiomycete fungus. An ascoma is the fruiting body of an ascomycete. Some ascomata, like morels, are mushroom-like in appearance, but they are structurally and taxonomically distinct.
Some, like cup fungi (e.g., Peziza) or morels, are clearly visible. Many others, especially those of plant-pathogenic fungi, are microscopic and require a lens to see.
The ascoma is the entire fruiting body structure. The ascus (plural: asci) is the microscopic, sac-like cell *inside* the ascoma where the spores (ascospores) are formed. One ascoma contains many asci.
Exclusively in mycology (the study of fungi), plant pathology, forestry, agriculture (when dealing with fungal diseases), and advanced biology courses. It is not a general vocabulary word.
