}} The Ceratobasidiaceae are a family of fungi in the order Cantharellales. All species within the family have basidiocarps (fruit bodies) that are thin and effused. They have sometimes been included within the corticioid fungi or alternatively within the "heterobasidiomycetes". Species are saprotrophic, but some are also facultative plant pathogens or are associated with orchid mycorrhiza. Genera of economic importance include Ceratobasidium and Thanatephorus (anamorph Rhizoctonia), both of which contain plant pathogenic species causing diseases of commercial crops and turf grass. TaxonomyThe family was created in 1948 by American mycologist G.W. Martin to accommodate species of corticioid fungi with heterobasidiomycete features (elongated sterigmata and basidiospores that give rise to secondary spores). He restricted the Ceratobasidiaceae to the genus Ceratobasidium, though including within the genus species later placed in Thanatephorus and Oliveonia. In 1981, Jülich created the order Ceratobasidiales to accommodate the family. By 1995, the order and the family contained 18 genera, including Ceratobasidium, Heteroacanthella, Oliveonia, Scotomyces, Thanatephorus, and their various synonyms and anamorphs.[2] Current statusMolecular research, based on cladistic analysis of DNA sequences, has now shown that the Ceratobasidiaceae do not belong to a separate order, but are part of the Cantharellales.[3] The genera Heteroacanthella and Oliveonia are not closely related to the Ceratobasidiaceae, but have been placed in the Auriculariales.[4] No species of the genus Scotomyces has yet been sequenced. Research on the septal pore ultrastructure of the little-known and atypical type species, Ceratobasidium calosporum, indicates that it is a member of the Auriculariales and is unrelated to other species of Ceratobasidium.[3][6] Technically, this means that the Ceratobasidiaceae belong within the Auriculariales, but this is a taxonomic problem that has yet to be resolved.[7] Habitat and distributionSpecies are mainly saprotrophic, occurring in the soil and producing fruit bodies on dead stems and plant detritus. Some occur on attached leaves and stems. Several species have been isolated from orchid mycorrhiza or from diseased crops and turf grass. Distribution appears to be cosmopolitan.[8] Economic importanceSeveral species of Ceratobasidium and Thanatephorus (including its anamorph Rhizoctonia) are opportunistic parasites of plants, causing a variety of economically important diseases of crops.[8] References1. ^1 {{cite book |title=Dictionary of the Fungi. 8th Ed. |veditors =Hawksworth DL, Kirk PM, Sutton BC, Pegler DN |year=1995 |publisher=CABI |location=Wallingford, Oxford |isbn= 978-0-85198-885-6 }} [1][2][3][4][5][6]2. ^1 2 {{cite journal |doi=10.3852/mycologia.98.6.937 |author=Moncalvo J-M |year=2006 |title=The cantharelloid clade: dealing with incongruent gene trees and phylogenetic reconstruction methods |journal=Mycologia |volume=98 |issue=6 |pages=937–948 |pmid=17486970 |display-authors=etal}} http://www.endophytes.org/teaching/advmycol/Cantherelloid.Moncalvo.pdf 3. ^1 {{cite web | url=http://www.indexfungorum.org/Names/Names.asp | title=Index Fungorum - Search Page}} 4. ^1 {{cite journal |doi=10.1017/S095375620100363X |vauthors=Weiss M, Oberwinkler F |year=2001 |title=Phylogenetic relationships in Auriculariales and related groups – hypotheses derived from nuclear ribosomal DNA sequences |journal=Mycological Research |volume=105 |pages=403–415 |issue=4 }} 5. ^1 {{cite journal |doi=10.2307/3761785 |vauthors=Chen CJ, Oberwinkler F, Chen ZC |year=2002 |title=Heterorepetobasidium, a new genus in the Auriculariales |jstor=3761785 |journal=Mycologia |volume=94 |issue=3 |pages=515–522 |pmid=21156522 }} http://www.mycologia.org/cgi/reprint/94/3/515.pdf 6. ^1 2 {{cite book |title=Rhizoctonia-forming fungi |last=Roberts P. |year=1999 |publisher=Royal Botanic Gardens |location=Kew |isbn=978-1-900347-69-3 |pages=239}} }}{{Taxonbar|from=Q3774448}} 2 : Cantharellales|Basidiomycota families |
