However, it is assumed to develop as a continuation of the wall of the hypha subtending the sporiferous saccule, is hyaline, and sloughs with loss of the saccule.
Thickness is unknown.
L3 is a thin layer which may be concolorous with the laminate layer of the spore wall, but it appears hyaline because of its thinness. The grayish green layer is presumed to be L3 of the spore wall. Color of the walls of the saccule or neck hypha are not mentioned. In reality, both phenotypes can be seen in spores of each species, depending on plane of focus and depth of field. Therefore, it is likely that these two species are synonymous.
