          Abstract

          El género Inonotus es considerado polifilético, dentro del cual se reconocen los géneros Inocutis, Inonotus s. str., Inonotopsis, Mesularia, Onnia y Pseudoinonotus. Se estudiaron 24 especies del género Inonotus s.l. basados en 304 ejemplares de las colecciones de hongos depositadas en los Herbarios ENCB, MEXU, BCMEX, IBUG, XAL, NY, BPI y ARIZ. En México se encontraron 24 especies, que corresponden a 5 de los 6 géneros segregados. Cuatro especies son nuevos registros para México: Inocutis rheades (Pers.) Fiasson y Niemelä, Inonotus arizonicus Gilb., I. porrectus Murrill e I. quercustris M. Blackw. y Gilb.; además, I. rickii (Pat.) D.A. Reid se registra por primera vez en su estado teleomórfico para Norteamérica. Se presenta una clave para la determinación de las especies mexicanas de Inonotus s.l.

          Translated abstract

          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.

              Hymenochaetales: a molecular phylogeny for the hymenochaetoid clade.

              The hymenochaetoid clade is dominated by wood-decaying species previously classified in the artificial families Corticiaceae, Polyporaceae and Stereaceae. The majority of these species cause a white rot. The polypore Bridgeoporus and several corticicoid species with inconspicuous basidiomata live in association with brown-rotted wood, but their nutritional strategy is not known. Mycorrhizal habit is reported for Coltricia perennis but needs confirmttion. A surprising element in the hymenochaetoid clade is a group of small white to brightly pigmented agarics earlier classified in Omphalina. They form a subclade together with some similarly colored stipitate stereoid and corticioid species. Several are associated with living mosses or one-celled green algae. Hyphoderma pratermissum and some related corticioid species have specialized organs for trapping and killing nematodes as a source of nitrogen. There are no unequivocal morphological synapomorphies known for the hymenochaetoid clade. However almost all species examined ultrastructurally have dolipore septa with continuous parenthesomes while perforate parenthesomes is the normal condition for other homobasidiomycete clades. The agaricoid Hymenochaetales have not been examined. Within Hymenochaetales the Hymenochaetaceae forms a distinct clade but unfortunately all morphological characters supporting Hymenochaetaceae also are found in species outside the clade. Other subclades recovered by the molecular phylogenetic analyses are less uniform, and the overall resolution within the nuclear LSU tree presented here is still unsatisfactory.
