BullRun

Psilocybin Mushroom Strain Guide

Origin

The BullRun strain of Psilocybe cubensis is a recent creation developed by the underground female mycologist known as “Shegrowsfungi,” who is based in Colorado. This strain is a unique hybrid resulting from an isolation of the Hillbilly and Hillbilly Squat (also known as Hillbilly Pumpkin) strains. The strain is known for its potency and its robust, large flushes making it very popular amongst modern growers.

The development of BullRun reflects Shegrowsfungi’s dedication to mycology and genetic experimentation, combining the reliability of Hillbilly’s growth characteristics with potent traits from Hillbilly Squat. Shegrowsfungi has become a recognized figure in the underground mycology community, contributing to innovations in Psilocybe cubensis cultivation since 2020 and gaining recognition at events such as the Oakland Hyphae MVP awards.

Appearance

BullRun mushrooms are characterized by their thick, sturdy stems and large, broad caps. The caps typically range in color from golden to caramel, often displaying a slightly darker center. This color gradient is further complemented by a textured surface that can appear slightly wrinkled or wave-like. The caps are supported by dense, fibrous stems that are white to off-white in color, capable of withstanding the weight of the large caps. When these mushrooms are bruised, they develop a bluish hue, which is a visual indicator of the presence of psilocybin, the psychoactive compound responsible for their intense psychedelic effects.

Expected Experience

BullRun mushrooms offer a more potent version of the Hillbilly strain, delivering stronger visual effects and deeper introspection. Users experience euphoria and heightened visuals where objects may “breathe” or shift, with colors appearing more vibrant. The trip often includes profound self-reflection, emotional breakthroughs, and enhanced appreciation for music and art. BullRun is a great choice for beginners and experienced users alike. Lower Dosage can still maintain a pleasant party atmosphere Hillybilly is known for but it ramps up quicker on higher doses.

Dr. Delic’s Field Notes

It feels like with the growing popularity of mushrooms new stains have started popping up at an exponential rate. I was seeing a friend who had just started a grow facility in Colorado during their legalization process and was presented with BullRun. Now I have had plenty of experiences with Hillbilly mushrooms and I think I may have taken these for granted in terms of potency.

We went to a cabin that weekend and I felt comfortable taking around 3.5 grams as I consider Hillbilly isolations to be more of a social strain in general. However, being around people was making me uncomfortable so I went outside.

“In the meantime, I went to get some firewood to put on the fire. Everything around me seemed sort of larger and more vivid. I noticed some patterns in the sand which seemed to really stand out. It was just tire tracks from the quad bike but they seemed really interesting and more defined for some reason. Like an artist had deliberately painted them to look like some significant pattern. I got some wood and put it on the fire. I noticed that my judgement and control of my body and surroundings was slightly impaired, like I was drunk, although my mind didn’t feel drunk. This was when I realized that I was really feeling the effects.”

It was at this point everyone began coming outside and I realized I was tripping a little harder than expected.

“I walked around for a while (feeling a little bit lost and disorientated) until I found a good spot away from the people and other loud music so I could enjoy the stars in peace. I lay down on the grass and dirt and looked up. I was amazed at what I saw.

“The whole sky was alive. The stars danced and moved in patterns, and the clouds passing overhead seemed to fly like Chinese dragons. The groups of stars took on a three-dimensional quality so that some seemed closer than others. The sky was pulsating with its own natural rhythm which the amazing music from my ipod was enhancing. I felt connected with the whole universe, like everyone and everything in it was part of the same whole. It was like the stars loved and cared for me and everything in the world. This was probably the highest point of the whole trip as I was still lucid, and the effects of the mushrooms hadn’t become too overwhelming. Had I had a nice blanket to lie on I probably could have laid there all night by myself just marveling at the beauty of the universe. Unfortunately, this was not the case, and I worried about the cold and if people might start to worry where I was and if I was ok.”

I was coming down when I got back and was feeling more at ease socializing. I explained what happened and we all had a giggle about it. Sometimes you just need some space.
