Microscopically, this fungus appears barrel shaped with thick walls, which best describes which type of conidia?
a. Macroconidia
b. Chlamydoconidia
c. Arthroconidia
d. Blastoconidia
C
Arthroconidia are formed directly from the hyphae by fragmentation through the points of septa-tion . When mature, they appear as square, rectangular, or barrel-shaped thick-walled cells. These are a result of the simple fragmentation of the hyphae into spores, which are easily dislodged and disseminated into the environment.
