Heterobasidiomycetes

In contrast, homobasidiomycetes, in addition to having aseptate basidia, generally have small regularly shaped sterigmata and spores that do not self-replicate.

[1] Certain taxa, such as Dacrymycetaceae, Ceratobasidiaceae or Tulasnellaceae, due to possessing a combination of hetero- as well as homobasidiomycetous features, have been difficult to definitively assign to either group, resulting in dissenting opinions among taxonomists.

[1] The subsequent rapid accumulation of molecular data in the past two decades has allowed mycologists to abandon the use of paraphyletic taxa and arrive at a consensus classification based on monophyletic clades that was finalized in 2007.

Heterobasidiomycetes correspond to most Basidiomycota other than the homobasidiomycetes: the subphyla Ustilaginomycotina (smuts), Pucciniomycotina (rusts and a variety of other forms), and from the subphylum Agaricomycotina the classes Tremellomycetes and Dacrymycetes, the orders Auriculariales and Sebacinales within the class Agaricomycetes, and the families Ceratobasidiaceae and Tulasnellaceae from the agaricomycete order Cantharellales (these members of the Agaricomycotina, save for the web-like Ceratobasidiaceae, are collectively known as the jelly fungi).
