Abstract
Los hongos corticioides (Agaricomycotina, Basidiomycota) son un grupo polifilético que comparte una morfología sencilla del basidioma (resupinada o efuso-refleja) y un mismo nicho ecológico (madera muerta). Por su modo de vida como descomponedores de la madera juegan un papel fundamental en los ecosistemas forestales y el ciclo del carbono, considerando además que la mayoría de sus representantes son hongos de pudrición blanca. Durante mucho tiempo se habían agrupado en una misma familia, Corticiaceae, pero gracias a la aplicación de las técnicas moleculares se ha demostrado que se distribuyen en los principales linajes de Agaricomycotina. Se han considerado organismos ampliamente distribuidos, lo que se ha explicado porque los nichos en los que se desarrollan son muy estables, las propias especies se suponen muy antiguas, permanecen más o menos invariables a lo largo del tiempo y la delimitación de las mismas se ha basado tradicionalmente en caracteres morfológicos...
Corticioid fungi (Agaricomycotina, Basidiomycota) are a polyphyletic group that shares a simple morphology of basidiomata (resupinate or effused-reflexed) and the same ecological niche (dead wood). As wood-decayers, they play a key role in forest ecosystems and the carbon cycle, with most members causing white rot in both hardwood and softwood. For a long time these fungi have been classified in a single family, Corticiaceae, but molecular phylogenetic analyses have shown that they are distributed among the major lineages within Agaricomycotina. Corticioid fungi have been regarded as widely distributed, which has been explained because the niches in which they develop are very stable, the species themselves are supposed to be very old, they have remained more or less unchanged over time and their delimitation has traditionally been based on morphological characters...
