Histoplasma capsulation is acquired by inhaling dust particles which contain bird or bat droppings that contain small spores (microconidia), the infectious form of the fungus.
terreus has ability to produce microconidia borne directly on a short conidiophores which arise laterally from vegetative hyphae(Walsh et al., 2003).
The shapes of hyphae, their thickness, color, septation status, presence of chlamydospores, microconidia and macroconidia, their shape, membrane thickness, their mutual relationship and their relationship with the conidiophore to which they were attached were examined at high magnification (10x40, Olympus BX41, Olympus, Tokyo, Japan).

Infection by inhalation of aerosolized H capsulatum microconidia primarily affects the lungs of immuno-suppressed individuals, although a variety of clinical presentations exist.
The isolated fungus presents mycelial growth with colorations between pink, purple and red in the center with white edges (Figure 1A), radial growth, oval microconidia with flattened base and grouped in chains (Figure 1B and 1D).
Microscopically with hyaline hyphae, septate and filamentous; septate macroconidia, fusiform with characteristic appearance of alantoespora, oval microconidia and in some cases chlamydoconidia of thick wall (25).
Infective propagules (microconidia) reach the lower airways, where they constitute a primary complex, and possible dissemination of the fungus via lymphatic vessels and hematogenous spread to other organs are likely to happen.
Microscope slides with the reproductive structures from minimum cultivation were observed and photographed in a light microscope (Olympus BX51, coupled with a camera Olympus DP70), showing shape and size of microconidia; size and septation of macroconidia, presence of isolate or chain chlamidospores.
Microscopically, the most consistent feature was the production of globose microconidia arranged in grape clusters.
cepae can produce macroconidia and microconidia, however, in the field chlamydospores are major form of the pathogen inoculum (Cramer, 2000).
