Primarily in mycology (study of fungi) and microbiology (specifically bacteriology), when discussing the ultrastructure of spores.
Rarely. Distinguishing the endosporium from other spore wall layers typically requires the higher resolution of an electron microscope.
It provides structural integrity and protection for the spore's genetic material and cellular machinery, aiding in survival during unfavourable conditions.
