Overview of current projects, to give you an idea what the future of the
Mushroom Nexus platform / company is about. The main goal and mission is education and exploring the cleansing possibilities of fungi on, for example, our soil, to heal the earth.

Recycling waste materials

Status: Ongoing

Currently collecting used coffee ground from around Utrecht City, and slowly scaling up. If you are a small business, in Utrecht and want to participate contact me, We take all used coffee grounds.

Working with Pleurotus ostreatus, a.k.a oyster mushroom, one finds himself in a good spot. As many companies already have established; used coffee grounds ‘waste material’ is perfect to grow oyster mushrooms on.

We have started a small scale oyster mushroom production for personal use and for friends and family. We collect coffee grounds on small scale of our coffee addicted patients.

Why use coffee grounds? It’s often seen as a waste product, ending up in the trash with all other non-recyclable products or on composting piles. The easiest way, in my opinion, to make the most use of these ‘waste materials’ is to grow mushrooms on them.

Why the oyster mushroom? Because this is a mushroom you can grow on a broad range of materials and is well known within society. Supposedly they have the beneficiary effect to Mycoremediation. An ideal candidate to feed the world and clean environments. You know… that environment we helped getting polluted in the first place.

Domesticating Porcini

Status: Ongoing

Harvested one of the most beautiful Porcini I have ever seen in my life. Created spore print from it and set some tissue on agar agar dish. Going forward will be experimenting with different kinds of substrate to see what works well for this culture.

One of the most sought after mushroom in the wild is the Porcini mushroom a.k.a. Cep, Boletus edulis. This one is currently farmed by going in to the woods and collect them by hand. Although I am a strong believer of foraging for food on small scale, massive foraging can lead to increased stress on the wild nature habitats as our ongoing trend to increase population sizes around the world.

So far there are no commercially viable cultivating options to grow Porcini in big numbers. This is due to the mycorrhizal nature of the mushroom. Our quest will be to find a solution to be able to cultivate this at home one day, both small and large scale. So nature can be at peace without the need of foragers.


Status: Ongoing

Submitted 3 talks to various festivals around the world to educate people about the importance of mushrooms for sustainable planet. All include also a workshop how to grow mushrooms at home. This workshop is also planned every 2 months. Check out the next workshop here.

Perhaps the most important thing for us is the education on the importance of growing mushrooms to save our planet! See workshops for more information.

Mycologists are few and far between. We are under-funded, poorly represented in the context of other sciences – ironic, as the very foundation of our ecosystems are directly dependent upon fungi, which ultimately create the foundation of soils.
