The Pucciniomycetes are a class of mushrooms (Basidiomycota). They also include the rust mushrooms (Pucciniales). Most of the representatives are parasites on plants, animals and fungi.
Features and way of life
Almost all representatives are parasites and form phragmobasidia and teliospores . Only Pachnocybe ferruginea is a saprobiont and forms holobasidia , and Platygloea disciformis is possibly a saprobiont. In the Helicobasidiales the dikaryophase can parasitize on plant roots ( Helicobasidium ), while the haplophase parasitizes on rust fungi ( Tuberculina ).
All representatives form hyphae , only with Septobasidium there are also yeast-like growth forms.
Systematics
Within the Pucciniomycotina, the Pucciniomycetes are the most basic group, and thus the sister group for all other representatives of the subdivision. The Pucciniomycetes comprise five orders:
- Septobasidiales
- Pachnocybales , the only representative of Pachnocybe ferruginea
- Helicobasidiales
- Platygloeales
- Rust mushrooms (Pucciniales)
The Pucciniomycetes correspond to the Urediomcycetidae, as the group is called by many workers.
