Scanning electron micrographs of infected digital skin of a wild frog, Litoria lesueuri, from Queensland, Australia, which died with cutaneous chytridiomycosis. (A) A cluster of mature sporangia are evident within the cells of the epidermis. The discharge tubes of the sporangia are visible projecting outwards from the cell surface. The plug of material within the discharge tube has been released in one of the sporangia (arrowhead). (Bar = 10 μm.) (B) Most of the cells in this field of the superficial layer of the epidermis contain sporangia, as evident by the bulging surfaces and the protrusion of unopened discharge tubes through infected cells (arrowheads). (Bar = 10 μm.)
