Like many millions of other people, mushroom expert Paul Stamets--who was featured in Netflix's Fantastic Fungi documentary--has seen HBO's The Last of Us and has some thoughts about it.

Posting on social media, Stamets said he's enjoying the series, but wants viewers to know that it's a work of fiction that plays on Mycophobia, which is the fear of fungi.

"Cordyceps can not infect humans," Stamets said, referencing the fungal infection that spreads from person to person on the TV series and in the video game it's based on.
