Mixiomycetes

Mixia osmundae is a kind of Mushroom Fungi ( Basidiomycota ), which parasitizes to King fern ( Osmunda ). Alone The type is the class Mixiomycetes.

Characteristics and lifestyle

Mixia osmundae is dimorphisch, so grows yeast -like and with hyphae. The spores are ejected, but it is not clear whether it is Meio or mitospores. The hyphae are multinucleate and have few septa.

In host tissue, the hyphae grow along the surface of the host cell, the host cell walls are thickened in the contact area. Under the cuticle of the leaf top - bottom as the hyphae form large, sac-like swelling. Of these, grow up sporogenous cells. The numerous spores are exogenously formed simultaneously and enteroblastic.

System

The Mixiomycetes are within the Pucciniomycotina the sister group of the Agaricostilbomycetes. They comprise only a order with a single type:

• Mixiomycetes Mixiales Mixiaceae Mixia Mixia osmundae

The species was counted until the 1990s sac fungus. Within the Pucciniomycotina they are isolated and are more closely related to a group.
