The Mississippi magic mushroom strain is one that is as prevalent as it is mysterious, which is an uncommon combination in the world of shrooms. It grows in abundance in Mississippi and the surrounding areas, yet little is known about when this strain was originally collected and isolated in a lab setting.

In this strain guide, we’ll explain what is known about the history of Mississippi magic mushrooms, the average potency of this strain, how to cultivate it from start to finish, and much more.

What Are Mississippi Shrooms?

Mississippi shrooms are a strain of magic mushrooms collected initially from somewhere in the Magnolia State, although little is known about its origins and lineage. This magic mushroom strain is far from popular in the magic mushroom community, possibly because it has an unknown history and an average potency. It’s one of the few well-known strains that you will likely have trouble finding spores for from online vendors.

We can say that the Mississippi strain — or the wild mushrooms that are most likely closely related to the strain — are still harvested in the wild throughout Mississippi. They’re found in horse fields most often in late spring, commonly growing on horse dung.

Strains vs. Species: What’s The Difference?

A species refers to a genetically distinct group of organisms. Strains refer to unique variants within a given species. 

When we talk about magic mushroom strains, we usually refer to varieties of Psilocybe cubensis

Other species of magic mushrooms include Panaeolus cyanescens, Psilocybe mexicana, Psilocybe tampanensis, Psilocybe azurescens, and over 100 others. 

Mississippi Shrooms Potency & Psilocybin Content

The psychedelic potency of the Mississippi strain is roughly average compared to other Psilocybe cubensis strains. While there isn’t enough analytical data to provide an accurate average potency for this strain, we estimate the potency is somewhere in the ballpark of 0.6% and 1.2% total tryptamine content (by dried weight). 

Mississippi Shroom Variations & Genetic Relatives

Given how little is known about the Mississippi strain, it’s difficult to say with certainty what strains are related to it. There is no evidence that any variations have been developed directly from the Mississippi strain. (such as an albino offshoot). 

Mushroom strains obtained from samples growing around the same region as the Mississippi strain include the Acadian Coast strain and the Dixieland strain

Where to Buy Mississippi Shroom Spores

Since the Mississippi strain is not a particularly popular one, you might have difficulty finding vendors who sell it.

Ralphster’s Spores is likely your best option if you live in the US. As of this writing, the strain is available in syringes. You can also check Spores 101, Lil Shop of Spores, and High Desert Spores, although neither of these companies carried the strain when we checked.

If you live in Canada, you may have a harder time, but you can check Sporeslab, Spores 101, and Spore Door, but none of these vendors carried the strain when we last checked.

If you live in Europe, you’re even less likely to find this strain. Local growers are unlikely to have a sample they can share, and stores like The Magic Mushroom Shop and Viking Spore weren’t carrying it at the time of writing.

How to Grow Mississippi Shrooms

Mississippi shrooms are quite photogenic, often displaying a large, bulbous cap and a decent-sized stem. The strain is known for producing a few large fruiting bodies interspersed with many other smaller ones. The strain naturally prefers mammal dung, but brown rice flour and rye grain both produce good harvests as well. Mississippi shrooms tend to be prolific sporulators, so make sure you harvest before the spores from your taller shrooms cover your shorter ones.

Similar Strains

When magic mushroom cultivators or users take kindly to a particular strain, they often look for similar varieties to try. Below are some strains that will provide a similar growing experience or trip to Mississippi mushrooms.

Dixieland Shrooms

As mentioned above, Dixieland shrooms hail from the same general location as the Mississippi strain. These shrooms have a lot of similarities with Mississippi mushrooms when it comes to physical appearance and growing patterns, likely because they are closely related.

Acadian Coast Shrooms

The Acadian Coast shrooms are just as mysterious as the Mississippi strain. Little is known about their origin, although it’s suspected that they grow along the Mississippi River, much like the Mississippi strain. These shrooms also have an average potency.

Panama Shrooms

The Panama shrooms were initially collected in Panama and isolated by Ralphster of Ralphster’s Spores. Little is known about the strain beyond its origin, but much like Mississippi shrooms, they grow several large shrooms with many smaller ones between them. They also have a similar potency to Mississippi shrooms.

Final Thoughts: Mississippi Shrooms

The Mississippi strain belongs to the species Psilocybe cubensis.

Mississippi shrooms were originally harvested near the Mississippi river, which suggests it’s closely related to the Acadian Coast and Dixieland strains — all of which share similar growth habits and potency.

The Mississippi strain is relatively resistant to mold and disease and has an average potency. It grows with some large shrooms interspersed with much smaller ones.
