Abstract: Mushrooms represent a little known source of food for herbivores despite their high quality provided by their high protein content. The main objective of this study was to determine which mushroom species were consumed by white-tailed deer on Anticosti Island (Québec, Canada). To do this, we collected 114 fecal samples from deer harvested in 2014 and 2015 on Anticosti Island. Fungi DNA was extracted from feces and amplified via polymerase chain reaction (PCR). Amplified fungi DNA was then sequenced with the method Illumina to identify mushroom species consumed by deer. Deer harvested appear to have consumed more than 580 mushroom species directly. We showed that adults consumed a higher mushroom diversity than juveniles and mushroom diversity consumed by deer varied greatly annually. Our results help understanding white-tailed deer food requirements and the role of mushrooms in their diet.
