Under certain conditions, India ink particles can penetrate the capsule of the opportunistic pathogen Cryptococcus neoformans. India ink penetration gave two distinct patterns, one as a ring in the middle of the capsule, and another as a double spot located at opposite poles of the cells. These spots were perpendicularly orientated to the bud. This pattern suggests the existence of a localized structure deep in the capsule that can accumulate large insoluble particles. Although the mechanisms responsible for the assemblage and maintenance of ring-like channels are not understood, their existence deep within the capsule implies a new level of complexity for this enigmatic structure.
