Investigating red yeast diversity from phyto- and mycospheres in Louisiana.
Ballistosporic red yeasts distributed throughout the three subphyla of Basidiomycota are ubiquitous components of the aerobiota as well as the phyllosphere. We surveyed for and found red yeasts in southern Louisiana on a variety of plant surfaces including leaves, fruits, and flowers. We also found red yeasts to be a common component of the mycosphere where they were isolated from a variety of niches such as gasteromycete glebas, mushroom fruiting bodies, and rust sori. Sporobolomyces pararoseus was the most common red yeast isolated and was found on the majority of sampled substrates. Others, such as Rhodotorula spp. (Pucciniomycotina) and Farizyma sp. (Ustilaginomycotina), were more limited in distribution. Phylogenetic diversity, potential new species, and microhabitat specialization will be discussed.
