Paul Stamets didn't start as a hero. In fact, when we first met him in Star Trek: Discovery, he was kind of a jerk. He was prickly, arrogant, and clearly annoyed that a war was getting in the way of his mushrooms. But honestly? That’s exactly why we love him.
In a franchise filled with polished Starfleet officers who always say the right thing, Stamets—played with a wonderful, neurotic energy by Anthony Rapp—felt like a real person. He’s a guy who just wants to do his science and maybe get a decent night's sleep. Instead, he ended up becoming the literal engine of the ship, injecting himself with tardigrade DNA and turning his own body into a biological navigation computer.
Talk about a career pivot.
The Real-World Magic Behind Paul Stamets
Most people don't realize that Paul Stamets isn't just a character name. He’s named after a very real, very famous mycologist. The real-life Stamets is an expert on all things fungi, from using mushrooms to save bee populations to cleaning up oil spills.
Bryan Fuller and the writing team actually brought the real Stamets in to talk to the writers. They were so blown away by his theories about how mycelial networks act as the "Earth's natural internet" that they scaled it up to a galactic level.

In the show, this became the mycelial network. It’s basically a subspace highway made of spores. It’s "f***ing cool," as Cadet Tilly famously put it—marking the first time the F-word was ever dropped in Star Trek history. Stamets, usually the one trying to keep things professional, couldn't even argue. He agreed.
That Relationship with Hugh Culber
We have to talk about the toothbrushing scene.
In season one, we see Paul and his husband, Dr. Hugh Culber (Wilson Cruz), just... existing. They’re in their pajamas, brushing their teeth, talking about their day. It was the first time Star Trek showed a committed gay couple in the main cast, and they did it with a quiet domesticity that felt revolutionary.
Then, they broke our hearts.

When Hugh was killed by Ash Tyler, it wasn't just a plot point; it was a trauma that defined Stamets for seasons. The way the show used the mycelial network to eventually bring Hugh back was weird and sci-fi-heavy, sure. But at its core, it was a story about grief. Stamets literally couldn't let go, and his connection to the "veins and muscles of the universe" gave him a way to reach through death itself.
Why the Spore Drive Still Matters
The spore drive is the most controversial piece of tech in modern Trek. Fans asked: "If Discovery could jump anywhere instantly in the 23rd century, why didn't Kirk or Picard use it?"
The show eventually answered this by making the tech a classified secret, but the personal cost to Stamets is what makes it interesting. He didn't just push a button. He became a hybrid.
Because of that tardigrade DNA, Stamets experiences time differently. Remember that time-loop episode "Magic to Make the Sanest Man Go Mad"? He was the only one who knew what was happening because he was "outside" the normal flow of time. It turned him from a scientist into something almost post-human.

A Quick Reality Check on the Science
- The Mycelial Network: In the show, it's a cosmic web. In real life, it’s a subterranean web of fungal threads that allows trees to "talk" and share nutrients.
- Tardigrade DNA: Discovery suggests humans can absorb DNA from these "water bears." In reality, a 2015 study claimed tardigrades had a ton of foreign DNA, but later research mostly debunked the idea that they're "DNA sponges."
- Astromycology: This isn't a real job yet, but NASA has actually funded research into "myco-architecture"—the idea of growing buildings on Mars using fungi.
The Growth from Grump to Dad
By the time the show moved into the 32nd century, the "grumpy" Stamets had mostly melted away. He became a mentor. When Adira Tal, the franchise's first non-binary character, joined the crew, Paul and Hugh stepped up as "Space Dads."
It’s a beautiful arc. He went from a guy who hated people "polluting" his lab to a man who built a found family in the middle of a lonely future.
Honestly, the character works because Anthony Rapp plays the "smartest guy in the room" trope without making it insufferable. You see the fear under the ego. You see the love under the snark. Whether he’s bickering with Jett Reno (the only person who can out-sass him) or sobbing in a mycelial forest, he’s the human anchor of a very high-concept show.
Actionable Takeaways for Trek Fans
If you want to dive deeper into the world that inspired the character, here is what you should actually do:
- Watch "Fantastic Fungi" on Netflix: It’s a documentary featuring the real Paul Stamets. The visuals of mycelium growing look exactly like the spore drive effects in Discovery.
- Read "Mycelium Running": This is the real Stamets' most famous book. It’s heavy on the science but explains why the showrunners thought mushrooms could save the universe.
- Rewatch "Choose Your Pain": This is the Season 1 episode where Paul first makes the jump. Pay attention to how his personality shifts immediately after—it’s the turning point for his entire character.
- Check out "Without You": If you love Anthony Rapp, listen to his memoir or see his stage show. It helps you understand the emotional depth he brings to Stamets' scenes about loss.
Paul Stamets proved that you don't need a phaser or a captain's chair to be the most important person on the ship. Sometimes, you just need a really good understanding of fungus and a husband who keeps you grounded.
