Mushroom spotting at BGS Keyworth

From food to biotechnology, the impressive fungal bodies we all know as mushrooms have a dynamic variety of beneficial uses. That’s just one of the reasons why colleagues from our Keyworth headquarters have started the BGS Mushroom Club.

What began out of curiosity and an excuse to explore the fascinating variety of fungi growing on site at Keyworth has now turned into a growing community of staff with a shared interest. The club gives passionate foragers a chance to share their knowledge and time, searching for and identifying different fungi whilst learning more about their contribution to local biodiversity. The club’s work is also helping to build a more holistic rewilding output on site, creating spaces for nature to thrive in a healthy and sustainable way, and is an important pillar of the BGS Environmental Sustainability Strategy.

I think fungi are one of the most fascinating groups of microbes. As a microbiologist, I probably am biased towards finding fungi cool, especially because I have learnt so many amazing facts about them! They are used in so many applications, from food to biotechnology, have many types of visually impressive fruiting bodies and can survive some of the most extreme conditions on Earth.

What I love most about the mushroom club is that it brings members of staff from many different areas together over a common love for these organisms, creating a community out of a shared interest.

So far, the club has identified around 20 different types of mushrooms in Keyworth, including the shaggy inkcap, candlesnuff fungus, violet-toothed polypore and even a variety that probably wouldn’t look out of place in the wizarding world: the obscure-sounding wolf’s-milk slime!

According to the club’s founders, the shaggy inkcap is particularly prolific on site throughout October to November. It is an edible species, forming tall, white pillars that dissolve as they grow, creating a black ‘ink’ which spreads the spores. This ink can be used to write with. Inkcaps can be found around the canteen and orchard area.

The wolf’s-milk slime has been a particularly interesting find this September. It is a slime mold that appears in the form of many tiny red balls that are filled with a pink paste, which pops out when squeezed and looks almost like toothpaste!

The group is collecting photos and videos of their finds, catalogued by the month they were found, in the hope that they will be able to predict which varieties we might see all year round. The aim is to improve the group’s identification skills and create a calendar and map of mushrooms describing which fungi can be found where on site and the time of year each species appears.

I’ve always been a fan of mushrooms, but I really started getting into fungi identification during lockdown. I love going out into nature and spotting all these amazing fruiting bodies that form part of  a much larger system which can grow for kilometres under the ground.

My favourite mushrooms are morels (so much I even have a tattoo of some) and I am fascinated by slime moulds. Starting the BGS Mushroom Club really began as an excuse to talk about the variety of cool fungi we find on site, but it’s been really useful to have a record of what’s growing and where, which could help inform future rewilding work.

Mushrooms should always be considered a wonderful addition to any site’s diversity as they play a key role in nutrient cycling by degrading organic matter and making it more available for plants and other soil dwellers. The club hopes to inform more people about the variety of mushrooms on our doorstep, which contribute to the great diversity of organisms we already have here in Keyworth.

Caution

Some mushrooms are highly poisonous and can be easily confused with edible species. Always exercise caution when foraging. If in any doubt, leave the mushroom in place.
