Moniliophthora perniciosa (previously Crinipellis perniciosa) is a fungus that causes "witches' broom disease" (WBD) of the cocoa tree T. cacao. This pathogen is currently limited to South America, Panama and the Caribbean, and is perhaps one of the best-known cocoa diseases, thought to have co-evolved with cocoa in its centre of origin (first recorded in the Brazilian Amazon in 1785). This fungus is hemibiotroph, with two characteristic phases: biotrophic (expanding and infecting, on living tissue) and saprotrophic (producing basidiospores, on necrotic tissue). The biotrophic stage, and what

Pseudomicrostroma juglandis is a plant pathogen.

The Tritirachiomycetes are class of fungi in the Pucciniomycotina. The class contains a single order, the Tritirachiales, which in turn contains the single family Tritirachiaceae. Currently, two genera, Tritirachium and Paratritirachium, are recognized in this lineage.

The Kriegeriales are an order of fungi in the subdivision Pucciniomycotina. Most species are known only from their yeast states and can be found in a variety of habitats, ranging from arctic waters to tropical ferns. Hyphal states produce auricularioid (laterally septate) basidia.
