... conidiophores closely packed together forming a bed-like mass. Acropetal refers to spore formation where the most recently formed spore is at the tip of a chain of spores. Usually seen ... related to formation of conidia, where the conidial initial enlarges prior to the formation of a septum separating the conidium from the conidiogenous cell (see blastospore). Blastospore spore formed following the ...
