Abstract

VALENZUELA, Ricardo; RAYMUNDO, Tania  and  CIFUENTES, Joaquín. The genus Inonotus s.l. (Hymenochaetales: Agaricomycetes) in Mexico. Rev. Mex. Biodiv. [online]. 2013, vol.84, suppl., pp.70-90. ISSN 2007-8706.  https://doi.org/10.7550/rmb.31605.

The genus Inonotus is considered polyphyletic of which the recognized genera are Inocutis, Inonotus s. str., Inonotopsis, Mesularia, Onnia, and Pseudoinonotus. Twenty-four species of the genus Inonotus s.l. were studied in this work based upon the examination of 304 specimens deposited on the Herbaria ENCB, MEXU, BCMEX, IBUG, XAL, NY, BPI, and ARIZ. In Mexico, we found 24 species, corresponding to 5 of the 6 genera segregated. Four of these species are new records: Inocutis rheades (Pers.) Fiasson and Niemelä, Inonotus arizonicus Gilb., I. porrectus Murrill, and I. quercustris M. Blackw. and Gilb. Furthermore, I. rickii (Pat.) D.A. Reid is reported as a teleomorphic state for the first time in North America. A key to identify the Mexican species of Inonotus s.l. is presented.

Keywords : Inocutis; Inonotus; Mensularia; Onnia; Pseudoinonotus; Hymenochaetaceae; taxonomy; Mexico.
