Histopathological preparations where it is possible to observe fungal invasion. a It is possible to observe a tangle of poorly-staining septate hyphae, with parallel, birefringent walls that branch dichotomously. Occasionally, these hyphae have bulging terminal expansions (H&E) (bar = 10 µm); b Special staining with Periodic Acid Schiff highlights the hyphal walls and terminal buds (bar = 10 µm)
