The Atractiellales are an order of the mushrooms (Basidiomycota). They are distinguished by having special organelles , the symplechosomes, live saprobionic and are the only order of the class Atractiellomycetes .

Features and way of life

The representatives of the Atractiellales are characterized by the presence of special organelles , the symplechosomes: a symplechosome consists of stacks of cisterns of the endoplasmic reticulum , which are connected by hexagonal filaments. Mature symplechosomoa are usually connected to mitochondria on both sides by the same filaments . The function of the symplechosomes is unknown.

In some of the atractiellales the septal pores are associated with microbodies , in others with atractosomes: these arise from cisterns of the endoplasmic reticulum that bend at the edge and thus form a spherical compartment.

The representatives live as saprobionts . They form hyphae , not yeast . A saprobionic, haploid hypha grows out of the germinating basidiospore . They form haploid conidia . The fruiting bodies are very diverse: there are stilboide (stalked with heads), resupinate (lying flat on the surface with basidia pointing upwards) and pycnidia-shaped fruiting bodies. Helicogloea and Saccoblastia throw out the spores ( ballistospores ), the others do not. Within the order there are also some asexual genera ( anamorphs ).

Systematics

The Atractiellomycetes are quite basal within the Pucciniomycotina , they are the sister group of all other classes with the exception of the Pucciniomycetes . The Atractiellomycetes comprise the only order Atractiellales with the following families and genera:

• Atractogloeaceae
  • Atractogloea

• Mycogelidiaceae
  • Mycogelidium

• Phleogenaceae : septal pores with atractosomes
  • Atractiella
  • Helicogloea (partly)
  • Phleogena

• Saccoblastiaceae : septal pores with microbodies
  • Helicogloea (partly)
  • Infundibura ( anamorphic )
  • Saccoblastia s. st.

• not assigned to a family:
  • Hobsonia (anamorphic)
  • Leucogloea (anamorphic)
