Key Identification Features
- When cut longitudinally, the rhizomorph shows three distinct tissues: an outer cortex, a subcortical layer, and a central core.
- gigantea, but electron microscopy reveals distinct ornamentation for each species: C.
- The base, which starts white and turns yellow, olive, or brownish with age, shows a less distinct reticulate pattern from rubbed-off spines.
- It has a fine, downy texture, and may sometimes split into distinct small areolate patches.
