Tuberculate spores distinguish the mold stage of Histoplasma from that of related pathogenic fungi. The tuberculations are not thickenings of the spore wall. They are extensions of the spore contents through the wall openings. The whole or the tip of a tuberculation may become detached and act as a spore.

Histoplasma Responses to Nutritional Immunity Imposed by Macrophage Activation
The fungal pathogen Histoplasma capsulatum resides within the phagosome of host phagocytic cells. Within this intracellular compartment, Histoplasma yeast replication requires the acquisition of several essential nutrients, including metal ions.

Surface architecture of Histoplasma capsulatum [PDF]
The dimorphic fungal pathogen Histoplasma capsulatum is the most frequent cause of clinically significant fungal pneumonia in humans. H. capsulatum virulence is achieved, in part, through diverse and dynamic alterations to the fungal cell surface. Surface components associated with H.
