SUMMARY
A decay of citrus fruits caused by a new species of Candelospora was found on an orange fruit at Citra, Florida, in 1932. Inoculations showed the fungus capable of decaying lemons, oranges, and grapefruit, mature fruit being more susceptible than immature fruit.
The fungus grown on glucose-potato agar has an optimum temperature for growth near 25.0° C., a minimum between 7.7° and 11.8° C., and a maximum between 30.4° and 35.0° C.
This fungus differs from Candelospora ilicicola Hawley, apparently the only other species of the genus described, in having smaller spores, in having fawn to vinaceous-colored mycelium instead of white tufts, in the lack of mucus in the heads, and in having peculiar aerial hyphae which terminate in swollen cells. Conidiophores grow out laterally from these beacon-like hyphae.
The fungus is described as a new species under the name Candelospora Citri.
