Ustilaginomycetes
Corn smut ( Ustilago maydis )
The Ustilaginomycetes are a group of smut fungi ( Ustilaginomycotina ). All representatives are parasitic flowering plants.
Characteristics and lifestyle
The Ustilaginomycetes are dimorphisch, so alternately form yeast -like and mycelial stages. They form teliospores and throw not away their basidiospores.
The Ustilaginomycetes live parasitically on angiosperms, mainly representatives of the sweet and sour grasses. The interaction zone with the host is great.
System
The Ustilaginomycetes form a monophyletic group one of the two classes of the smut fungi. The Ustilaginomycetes itself be divided into two orders:
- Order Urocystales, mainly form Holobasidien
- Order fire Fungal ( Ustilaginales ), mainly form Phragmobasidien
The Glomosporiaceae family can be assigned to any order.
