Taphrinomycetes - Taphrinales
The class of Taphrinomycetes and its only order the Taphrinales contains more than 100 species of plant pathogenic fungi. They cause leaf deformations, blistering and gall-like symptoms. For example, Taphrina deformans causes leaf curl on peach and nectarine.
The life cycle includes a saprophytic, yeast-like haploid state. The plant pathogenic diploid state forms hyphae which spread within the host plant. Eventually a naked layer of asci, but no fruiting body, is formed on the plant surface. The asci contain 8 haploid ascospores each. The ascospores develop into the the yeast-like stage and multiply by budding.
The following genera and individual species are currently entered under this group:
