Two species of fungi grow on tree-frog egg masses in Nicaragua and Costa Rica, Central America. One of the species having long, slender hyphae was found infecting the eggs of the centrolenid Centrolenella prosoblepon and it infected eggs of other tree-frogs when inoculated experimentally. The fungus killed the developing embryos only when infestation was intense. A short-hyphae species occurs on the eggs of the hylids Agalychnis callidryas and A. annae. Although centrolenid egg clutches are not usually infected under natural conditions, the fungus can be readily inoculated experimentally. Apparently the adult centrolenid accompanying the eggs provided some immunity against fungal infections. Both fungi appear to lack reproductive structures and, therefore are provisionally placed in Mycelia Sterilia, a group of imperfect fungi.
