conidium

These spores are conidia, asexually-produced reproductive cells, and are termed a Stage I infection.

The fungus reproduces asexually, “meaning it makes a type of spore called a conidium,” Flaherty says.

Bees have been shown to carry the spores of Sclerotinia and infect the stigmas of Bilberries, etc., with them; and flies convey the conidia of Ergot from grain to grain.

According to his view, the ascus is in effect the sporangium with several spores, the conidium the sporangiole with but one spore, and that not loose but fused with the sporangiole wall.

The spores of Ferns, ascospores, and some conidia are also liberated explosively.
