They were divided into four classes&colon; Phycomycetes, Ascomycetes, Basidiomycetes, and Deuteromycetes. Geastrales is an order of gasterocarpic basidiomycetes (fungi) that are related to Cantharellales. Phenolic acids can be found in mushroom Basidiomycetes species. Phenolic acids can be found in mushroom basidiomycetes species. His studies of mating and intersterility in basidiomycetes are now classical. Rhizopogon is a genus of ectomycorrhizal Basidiomycetes in the family Rhizopogonaceae. He divided all basidiomycetes between these two groups. Most phytopathogenic fungi belong to the Ascomycetes and the Basidiomycetes. It also has a symbiotic relationship with fungi, specifically ascomycetes and basidiomycetes. Fungi such as "Basidiomycetes" can also be used to build logical circuits. The terms basidiomycetes and ascomycetes are frequently used loosely to refer to Basidiomycota and Ascomycota. Sexual reproduction in basidiomycetes is similar to that of the ascomycetes. Examples of dikaryon can be found in ascomycetes and basidiomycetes. The smuts are grouped with the other basidiomycetes because of their commonalities concerning sexual reproduction. For the most part, this fungus exhibits a life cycle characteristic of basidiomycetes.
