Fertilization occurs once the conidium of a different mating type makes contact with the trichogyne, a structure of the protoperithecium.
12.
The two cells from both the protoperithecium and conidium fuse, yet their nuclei remain separate until ascus formation has occurred.
13.
A conidium may form germ tubes ( germination tubes ) and / or conidial anastomosis tubes ( CATs ) in specific conditions.
14.
After conidium production, the conidiogenous cell elongates before producing another conidium atop a small denticle ( a narrow projection bearing a conidium or sporangium ).

After conidium production, the conidiogenous cell elongates before producing another conidium atop a small denticle ( a narrow projection bearing a conidium or sporangium ).
16.
After conidium production, the conidiogenous cell elongates before producing another conidium atop a small denticle ( a narrow projection bearing a conidium or sporangium ).
17.
The conidiophores they produce are unicellular, thick-walled ( 2 ?m ), and usually simple with a single terminal conidium also called an aleurioconidium.
18.
After the first conidium is blown out, before it matures, the apex of the conidiophore directly below blows out a second conidium from the opposite side.

After the first conidium is blown out, before it matures, the apex of the conidiophore directly below blows out a second conidium from the opposite side.
20.
The sexual cycle is initiated ( i . e . fertilization occurs ) when a cell ( usually a conidium ) of opposite mating type contacts a part of the trichogyne ( see Figure ).
