Pseudothecium vs Pycnidium - What's the difference?
pseudothecium | pycnidium |
An ascocarp resembling a perithecium but whose asci are not regularly organised into a hymenium and are bitunicate, having a double wall which expands when it takes up water and shoots the enclosed spores out suddenly to disperse them.
In certain fungi, a flask-shaped cavity from the surface of the inner walls of which spores are produced.
(Webster 1913)
