phylogenetics of Cantharellales. Analyses of Matheny et al. (2006b) suggest that Tulasnella<br />
is nested within the Cantharellales, but it could also be the sister group to Cantharellales<br />
s.str. (Moncalvo et al. 2007). If so, then it may be appropriate to segregate Tulasnellales<br />
from Cantharellales s.str.<br />
Exemplar genera: Cantharellus Fr. 1821, Botryobasidium Donk 1931, Craterellus Pers.<br />
1825, Tulasnella J. Schröt. 1888.<br />
Order: Corticiales K. H. Larss., ord. nov.<br />
MycoBank no.: MB 501299<br />
Basidiomata resupinata, effuso-reflexa vel discoidea; hymenophora laevia; systema hypharum<br />
monomiticum; dendrohyphidia raro absentia; basidia saepe e probasidiis oriuntur. Cystidia presentia vel<br />
absentia. Sporae hyalinae, tenuitunicatae, albae vel aggregatae roseae.<br />
Typus: Corticium Pers. 1794.<br />
Basidiomycetes with effused or discoid (Cytidia) basidiomata, a smooth hymenophore,<br />
and a monomitic hyphal system with clamped, rarely simple-septate, hyphae.<br />
Dendrohyphidia common. Species with or without cystidia. A probasidial resting stage<br />
is present in many species. Spores smooth, in masses white to pink. Saprotrophic,<br />
parasitic, or lichenicolous.<br />
Equivalent to Vuilleminiales Boidin, Mugnier & Canales 1998 and the corticioid<br />
clade (Binder et al. 2005; Larsson et al. 2004). Boidin et al. (1998) explicitly included<br />
Corticium in their new order, as a member of the family Vuilleminiaceae Maire 1902.<br />
Jülich (1981) also placed Corticium in Vuilleminiaceae but referred them to Aleurodiscales<br />
Jülich 1981. Corticium is the type of Corticiaceae Herter 1910, a family name conserved<br />
