Did you ever hear of waxcaps? These colourful wild mushrooms love to grow in old, undisturbed grasslands and make a spectacular appearance in autumn. They belong to a group of fungi known for their smooth, thin stems, widely spaced gills and waxy-looking caps, which can be red, yellow, orange, green, pink or white.

Eleven curious GoodGymers were tempted enough to learn more about these incredible mushrooms to forgo their usual Sunday afternoon plans and head to Walpole Park instead. In particularly windy conditions, the GoodGymers joined Richard and two other Ealing Greenwayers for a fungi survey in support of Plantlife – an organisation whose mission is to secure a world rich in wild plants and fungi.

Any activity in Walpole Park this autumn wouldn't be complete without an air of controversy thanks to Ealing Council’s plan for a temporary, 1,200-seat Troubadour theatre, which has sparked strong local opposition. Among the campaigners’ concerns was the loss of green space, whose ecosystem they believe should be protected rather than sacrificed for a large-scale theatre development. Since waxcaps are a rare, species-rich grassland indicator, heavens knew what would happen if the GoodGym and Greenwayer expedition found these fungi in the park!

Armed with flags to mark the locations of the fungi we discovered and litterpickers (to expand our impact beyond mushroom-spotting), we formed a line abreast, standing shoulder to shoulder. We marched forward, eyes firmly fixed on the ground not to miss even the tiniest fungi. Tiny they certainly were - and not quite waxcap-looking.

Our line-abreast phalanx swept through about three-quarters of the park's grassland (and woodchip-land), discovering a variety of fungi and collecting about a bag of litter that hadn't yet been blown away by the wind. No waxcaps, alas!

Walpole Park may not be an ancient grassland, but the hope is not lost. During our quest, we bumped into a shroom-savvy Selborne Society member, who pointed out that the dry summer had been rather merciless to fungi and that he wouldn't expect to find waxcaps in Walpole Park. He gave us some hints about other promising locations, so you may yet see another mushroom survey this autumn, before the first frosty days arrive.

Goodgym were back at Western Road Urban garden to finish a job that was started previously. The small mighty team tackled the trenches once again and carried on digging. Then the pipe came in play : the team laid down the pipe and wrapped it with some fabric/mesh before covering it with soil. Lena really did a great job wrapping the pipes with the mesh.The pipe disappeared like the trenches: goodgym are real magicians. Scott and Afshin also helped level the area for the tank and reposition the frame. Small group but great achievement. The group enjoined the usual samosas and fruit provided by Janpal.

Seven months have passed since GoodGym last supported Walpole Park, making it clear that sessions in this beloved green space in the heart of Ealing are very much an autumn-winter thing. The temperatures, however, did little to signal the changing season. GoodGymers still happily sported short sleeves and shorts, while the park, despite being pitch black, teemed with nightlife, wildlife and parklife. Frolicking people and foxes alike were seen – or smelled!

The park welcomed back some seasoned Walpolers: Chris, Harvey, Steph Ducat, Sevan and Kash. Amy and Scott, who joined GoodGym over the spring and summer months, got their first taste of a nighttime Walpole Park session. Breda also visited from GoodGym Hounslow and was amazed by the abundance of tools sourced by our friend Richard.

Yes, Richard! The long-missed Ealing Greenwayer, best known to us from Pear Tree Park, made a comeback wearing his kitchen garden volunteer hat. He also hosted a historic session: the first time a task owner was actually present in Walpole Park during one of our activities!

Richard showed us a secret pocket of leafy compost, which we were tasked with moving to the kitchen garden's compost bins. The mulch was very well concealed indeed. Even when led to this obscure (but surprisingly well-lit, thanks to Ealing Studios) spot, the compost was hiding in plain sight.

"We are actually standing on a layer of composted leaves" – Richard.

To get to the mulch, we first had to excavate it. And it wasn't as quick and easy as simply shovelling: the compressed leaves were intertwined with roots. Some of us relished the challenge of seemingly endless digging and the accompanying upper-body workout.

"It's like a canoeing trip. After the first half an hour your arms are dead, but then you're numbed and just carry on." – Amy.

Supplied by Richard with barrows in addition to two larger trolleys, we managed to fill one of the compost bins almost to the brim. It was a successful first Walpole Park session of the season, but surely not the last one. So watch this space for more night-park-life coming up this autumn and winter!

A year after their last volunteering session at Our Lady of the Visitation Primary School in Greenford, a chance encounter in central Ealing brought Team GoodGym back to find out what had happened to the planned wildlife reserve. Last year a veg patch and the pond were well established, with the rest of the space still needing to be cleared and planted.

Returning today, Rachel and her keen pupils had been busy. They had:

• Completed the woodchip path
• Grown some beautiful sunflowers
• Planted wildflower seeds to create a Nectar Highway
• Created a hedge-y area to attract hedgehogs
• Been studying the lifecycle of hundreds of newts in their pond

Lots of discoveries for curious minds.

Other things hadn't changed from last year. The path through the wildlife reserve had again become a bramble highway. This was not the type of highway the school wanted to encourage. Most of the brambles were rooted in the flowerbeds off the path, so while some of the team got chopping, others dove into the dried out beds to dig out any roots that they could.

Therese, Maria, Kash and Steph chopped and dug their way through the whole session, clearing the space. As the bramble levels dropped off, Amy, Scott and Sevan moved onto task 2, emptying the soil from giant planters. Task owner Rachel saved the plants that had survived the summer, then the planters were dragged across the playground. The soil was dug out and placed in ton bags until they were light enough to lift and tip what was left. Six planters later, they were done.

Everyone enjoyed their session at the school, with some marvelling at how much space the school had available. Rachel was really impressed with what the large team achieved and she still has big plans and projects in the pipeline, so we could be back again, sooner rather than later.

"Thank you so much. Huge difference." - Rachel
