Light micrograph of the fungus Talaromyces marneffei showing conidiophores (branches with terminal chains of dots) and septate hyphae (light blue). Hyphae are the branching, filamentous structures of a fungus, that in this species are separated by septa (walls) into cellular compartments. Conidiophores are specialised hyphae that produce asexual spores (reproductive cells, dots) called conidia. T. marneffei can cause an infection called talaromycosis. Treatment is with antifungal medication.
