Boletus rubriceps is a species of bolete fungus in the family Boletaceae. Although it was officially described as new to science in 2014, the bolete had previously been reported as either Boletus edulis or B. pinophilus. Molecular analysis showed that it was sufficiently different from other morphologically similar Boletus species to warrant designation as a distinct species. It is found in the southwestern United States and southern Rocky Mountains, where it associates with spruce, pine, and sometimes fir.

The fruit bodies are edible and highly sought after; they are often sold in farmer's markets of Arizona, New Mexico, and Colorado, and are used in some restaurants. The specific epithet refers to the reddish color of the caps (Latin ruber = "red"; caput = "head" or "cap"). Common names given to the bolete include "Ruby Porcini", "Rocky Mountain red-capped king bolete” or “Rocky Mountain red".

We offer hand picked dried boletes and freshly foraged boletes when seasonally available.

What Is An Agar Plate?

An agar plate is a petri dish with solidified nutrient solution (I make mine with light malt extract, generally). The dish is sealed with parafilm to keep it sterile while the transfer colonizes the plate.

The mycelial bodies grow on our agar plates in sterile incubators before being shipped to you!

How Do I Store Agar Plates?

Keep your agar plates ideally in the fridge, within a ziplock bag. Let them come to room temperature before opening them - it'll prevent condensation!

How Do I Use Agar Plates?

Grab your scalpel and get to work! Need a scalpel? Check my gear page!

Slides from agar plates can be propagated onto other mediums very easily. The beauty of agar plates is the ability to be absolutely certain that your sample is healthy and clean!

When Will My Agar Plate Ship?

All of my agar plates are made-to-order. This ensures that you have nothing but the freshest, most voracious mycelium when it gets to your doorstep.

Please check for your individual species on this page to see colonization times.

If you're interested in ordering agar plates and other items like liquid culture, or mushroom spores, you can have your order shipped in two by adding this item!

What Comes In My Package?

For each agar plate in your order, you'll receive a healthy, colonized agar plate, and an additional piece of parafilm in case you need to reseal it.

What if Something Goes Wrong?

If you any questions as to the density, sterility or other concerns about your order please email me directly at

Under no circumstances contact us about cultivation of active spores regardless of legality in your home location. Doing so will result in a cancellation of all open orders and denial of any future orders.

While all of our products are made in the most sterile conditions possible, sometimes contamination happens! I'll make it right!
