Paul Stamets/Hugh Culber is the pairing of Paul Stamets and Dr. Hugh Culber, a married couple, in the Star Trek: Discovery fandom.


Stamets and Culber are both stationed aboard the Discovery. As Chief Engineer, Paul Stamets makes the spore drive work consistently by inject himself with tardigrade DNA and acting as the navigator. Stamets mental and physical health appears to suffer as he continues to interact with the spore drive, but he initially keeps this information from his husband.

Dr. Hugh Culber is murdered by Ash Tyler / Voq.

In the second season of the show it is revealed that Culber had been trapped in the mycelial plane since his death. He is rescued and brought back to life. Despite this, and as a result of his death in the first season, Culber has problems going back to his old life and breaks his relationship with Stamets.

At the end of the season, after a conversation with Jett Reno in which she tells him how she lost her wife, and after Stamets ends up injured in sickbay, they rekindle their relationship.


This is the first canon LGBT relationship in the Star Trek Universe, and it is the most popular ship in the DCS fandom.

Ship Names

do you know if there's a ship name for Hugh/Paul?
not an established one but Wilson called Paul his “space boo” at NYCC (x) so we felt Space Boos was appropriate.[1]

There were initially a multitude of ship names assigned to this pairing, including Stulber, Space Boos, ShroomDoc, Culbets and Stamber. In October 2017, when actors Anthony Rapp and Wilson Cruz, appeared on the Star Trek: Discovery aftershow After Trek, they gave their blessing to the couple name Culmets.

We fans certainly discussed the ship name before the After Trek episode.

Culmets was my favorite. I think SpaceBoos is cute too.

I was screaming like the crazy fangirl I am when I saw After Trek and #Culmets became 'official'. [2]
