The Agaricostilbomycetes are a class of the mushroom (Basidiomycota).

Features and way of life

In the cell wall is fucose as a constituent. The septal pores are not associated with microbodies . The basidiospores are not septate during germination.

Most of the representatives are teleomorphs , all are dimorphic, i.e. they form hyphae and yeast stages. All sexual species form phragmobasidia .

There are no plant parasites in the class that are otherwise widespread in the subdivision. Some representatives are parasites on mushrooms, they form tremelloid haustoria cells, as they otherwise occur mainly in the tremellales . Here, however, they have two cell nuclei , one in the Tremellales.

Agaricostilbum pulcherrimum has a unique feature of the Pucciniomycotina: the spindle pole bodies (SPBs, functionally correspond to the centrosome ) are separated nucleoplasmic in prophase I of meiosis , not cytoplasmic: the SPBs with the lengthening middle pieces get into the nucleoplasm through the ruptured nuclear envelope. With Agaricostilbum the nucleus division takes place in the mother cell, not in the budding cell.

Systematics

The Agaricostilbomycetes are the sister taxon of the Mixiomycetes . The Agaricostilbomycetes comprise two orders with the following families and most genera:

Agaricostilbales
- Agaricostilbaceae : the basidiospores are formed in a yeast-like manner.
  - Agaricostilbum : often on dead palms.
  - Bensingtonia (in part)
  - Sterigmatomyces ( anamorphs )
- Chionosphaeraceae : the basidia are gasteroid, the basidiospores are formed simultaneously per basidia.
  - Chionosphaera : possibly fungal parasites
  - Kurtzmanomyces (anamorphic)
  - Mycogloea (in part):
  - Stilbum
- Kondoaceae
  - Bensingtonia (in part)
  - Kondoa
Spiculogloeales
- Mycogloea (partly)
- Spiculogloea : fungal parasites that grow intrahymenially.
- Sporobolomyces (partly, anamorphic)

The two orders as well as the class are monophyletic taxa in the description cited here .
