چکیده

Antecedentes y Objetivos: El género Cortinarius está constituido por hongos ectomicorrícicos caracterizados un velo parcial a modo de “cortina” aracnoide, esporada, color marrón óxido anaranjado ocráceo basidiosporas rugosas, arrugadas o verrugosas sin poro apical. hesleri se ubica en el subgénero Telamonia; reconoce principalmente sus basidiomas colores que abarcan desde los tonos rojos anaranjados. Se encuentra distribuida Norteamérica Canadá Estados Unidos América. Los inventarios fúngicos facilitan reconocimiento especies para una determinada área geográfica. objetivo este trabajo es presentar C. como primer registro México. Métodos: recolectaron especímenes bosques Quercus del municipio Victoria estado Tamaulipas, elaboró descripción macro micromorfólogica la especie, tomaron fotografías macroscópicas in situ e ilustraciones las estructuras microscópicas, su posterior análisis identificación taxonómica mediante literatura especializada correspondiente. ejemplares estudiados depositaron herbario micológico José Castillo Tovar Instituto Tecnológico Ciudad Victoria. Resultados clave: cumplen con características original así mismo hábitat al asociado cual distribuye. descrita primera vez caracteriza anaranjado, esporas ornamentadas elipsoides (7-)8-10(-12) × (5-)5.5-7 µm asociación vegetales bosque mixto Quercus-Pinus. Conclusiones: distribuido ampliamente parte norte América, alcanzando distribución más meridional actualmente conocida Tamaulipas Por potencial ectomicorrícica forestales géneros Quercus, Pinus Carya, pudiera encontrarse junto estas plantas otros sitios noreste oriental hacia sur

Lower level relationships in the mushroom genus Cortinarius (Basidiomycota, Agaricales): a comparison of RPB1, RPB2, and ITS phylogenies.

We sampled and analyzed approximately 2900bp across the three loci from 54 taxa belonging to a taxonomically difficult group of Cortinarius subgenus Phlegmacium. The combined analyses of ITS and variable regions of RPB1 and RPB2 greatly increase the resolution and nodal support for phylogenies of these closely related species belonging to clades that until now have proven very difficult to reso...

Cortinarius section Bicolores and section Saturnini (Basidiomycota, Agaricales), a morphogenetic overview of European and North American species

Cortinarius is the largest genus of ectomycorrhizal fungi worldwide. Recent molecular studies have shown high levels of morphological homoplasy within the genus. Importantly, DNA phylogenies can reveal characteristics that have been either over- or underemphasized in taxonomic studies. Here we sequenced and phylogenetically analysed a large set of pan-European and North American collections tax...

Phylogeny of the Pluteaceae (Agaricales, Basidiomycota): taxonomy and character evolution.

The phylogeny of the genera traditionally classified in the family Pluteaceae (Agaricales, Basidiomycota) was investigated using molecular data from nuclear ribosomal genes (nSSU, ITS, nLSU) and consequences for taxonomy and character evolution were evaluated. The genus Volvariella is polyphyletic, as most of its representatives fall outside the Pluteoid clade and shows affinities to some hygro...

Guyanagaster, a new wood-decaying sequestrate fungal genus related to Armillaria (Physalacriaceae, Agaricales, Basidiomycota).

UNLABELLED PREMISE OF THE STUDY Sequestrate basidiomycete fungi (e.g. "gasteromycetes") have foregone ballistospory and evolved alternative, often elaborate mechanisms of basidiospore dispersal with highly altered basidioma morphology. Sequestrate fungi have independently evolved in numerous Agaricomycete lineages, confounding taxonomic arrangements of these fungi for decades. Understanding ...

The enigmatic Squamanita odorata (Agaricales, Basidiomycota) is parasitic on Hebeloma mesophaeum.

Squamanita odorata is an agaric which is parasitic on unrecognizable, previously unidentifiable sporophores of a fungal host that is transformed into galls at the bases of the parasite's sporophore. Amplification and sequencing portions of the nuclear (ITS) and mt rDNA from three samplings originating from two sites (from France and from Switzerland) demonstrate that the galls produce sequences...
