I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.
What we do. Every page goes through several hundred of perfecting techniques; in live mode. Quite the same Wikipedia. Just better.
Great Wikipedia has got greater.

Urediniomycotina

Pucciniomycotina is a subdivision of fungus within the division Basidiomycota. The subdivision contains 10 classes, 21 orders, and 38 families.[3] Over 8400 species of Pucciniomycotina have been described - more than 8% of all described fungi.[4][5] The subdivision is considered a sister group to Ustilaginomycotina and Agaricomycotina, which may share the basal lineage of Basidiomycota, although this is uncertain due to low support for placement between the three groups. The group was known as Urediniomycetes until 2006, when it was elevated from a class to a subdivision and named after the largest order in the group, Pucciniales.[1]

Morphology

There is a high morphological diversity in the Pucciniomycontina. The sporulating forms range from macrobasidiocarp to single-celled yeasts.[4] The presence of simple septal pores, and disc-like spindle pole bodies unites Pucciniomycotina and distinguishes it from the sister groups.[6] The predominance of mannose in the cell walls is also a uniting feature of the group.[7]

Ecology

Pucciniomycotina have a diverse range of ecologies as insect parasites, mycoparasites, and orchid mycorrhiza; some have been detected in soil and water or asymptotic members living on leaves. Most are plant pathogens. Many Pucciniomycotina are rust fungi and are placed in the order Puccinales that contains roughly 7800 species (c. 90% of the group).[4][8] Some members of the group are of economical importance as a pathogen on a wide range of commercial plants, e.g. wheat. Pucciniomycotina is a cosmopolite and exists all over the world.[9] Pucciniomycotina may even be present in Arctic ice, and in oxygen-poor deep sea habitats.[6]

Life cycle

Some members are only known from their anamorphs, and asexual stages predominate in most; in some species this is the only known form. A striking characteristic of Puccinomycotina is the unique developmental pattern.[4] Rust Fungi or plant pathogenic members in Puccinales have the most complex life cycles known in the fungal kingdom, with five different spore stages.[10] Studies have shown that Puccinales also has one of the largest genomes in the fungi kingdom, and that genome size expansion may be common. This explains the complex life cycles within the group.[9]
