The New Student's Reference Work/Conidia
Conid′ia (in plants), asexual spores of certain fungi, which are formed by cutting off a series of cells from special branches of the mycelium, resulting in more or less extensive chains of spores which separate easily. Such spores are well displayed by the mildews and the æcidium forms of rusts. They are often called conidiospores. The singular of the name is conidium.
