Basidiomycetes are the only fungal group that produces lignin peroxidases, which are chemicals that can break down lignin and lignified tissues. Basidiomycetes growing within a fallen log would get less nutrition than ascomycetes because more of the cellulose in the log would be available to be broken down and absorbed.

Question

Quizplus · Accepted Answer

Basidiomycetes are known for their ability to break down lignin and lignified tissues, which actually allows them to access the cellulose more efficiently than many other fungi, including ascomycetes. This ability to degrade lignin gives them an advantage in decomposing wood and accessing the cellulose for nutrition.
