We are having a wet spell here in North Florida with fungus out everywhere. I noticed a yellow crust on the underneath of oxalis leaves. Some of the plants looked close to death with shriveled leaves while others had just a few specks. I have tentatively identified the organism as Puccinia oxalidis but really just by matching photos on the internet. Has any one ever had this fungus? Does it spread to other plants in the landscape? Can it be treated? So far, I have just cut off the foliage of severely effected plants.
