Not that it looks like a fun(guy)gi though

Ooooh Croc..... that looks very promising! Thanks for that. I'll let her know.
Sarah, my friend, says thanks too Croc! She was beginning to think she'd been invaded by some triffid like life-form from the Iceland volcano eruption!
I'm not 100% sure... but I think it grows like knotweed too... in which case getting shot of the stuff is hard work... I think you can go down the route of treating it with the paint on weedkiller... every time a bit sprouts up.
The other way is to literally dig it out... with a trowel... getting every last bit of root up.. and trying not to fragment the root as this will just make it worse.
If its coming from next door then they need to get rid of it too.
I'll have a look later and see if it is a rhizome one!.
My friend lives a mile up the road and a few years ago they moved into this beautiful brand new bungalow... their dream house! It really is gorg. A few months after moving in she starting talking about this weird asparagus stuff that kept growing in her garden... then I got a frantic text message... it was japanese knotweed! It had started forcing its way through the decking on the oriental pagoda thingy... had forced its way into the sides of the Koi ponds... and was heading towards the house.
She has horsetail too!
I'll text her tomorrow and ask her about it. I know that 4 years on she is slowly winning the knotweed war! Its a constant & slow job of painting on they glyco something weedkiller... but its starting to work.
I'd go straight for the hydrochloric acid then!
Spooky!
Just as well it's not the fungi croc posted then.
Control
Non-chemical controls
Removing horsetail by hand is difficult. Although rhizomes growing near the surface can be forked out, deeper roots will require a lot of excavation. Shallow, occasional weeding is not effective and can make the problem worse, as the plant can regrow from any small pieces left behind. However, removing shoots as soon as they appear above the ground can reduce infestation if carried out over a number of years.
If horsetail appears in lawns, it can be kept in check by mowing regularly.
Chemical controls
Infestations of horsetail can be weakened with weedkiller.
- On vacant soil, where there are no herbaceous perennials, bulbs or crops, you can spread granules containing dichlobenil (Casoron G4 Weed Barrier) over the ground to inhibit new shoots.
- Weedkillers containing glyphosate (e.g. Roundup, Tumbleweed, Weed Buster and Knockdown Systemic) can be applied in late summer when growth is strong. Before using, bruise the shoots with a rake to ensure effective penetration.
- Glufosinate ammonium (e.g. FITO Garden Weedkiller and Knockdown Weedkiller) will kill horsetail shoots, and may also weaken the root system. Take care when applying these herbicides, as they are not selective and will kill cultivated plants too. Follow the manufacturerâs instructions carefully.
Remember: horsetail is persistent, and several applications - possibly over a number of years - may be necessary to completely eradicate the problem.
I have ground elder... well .. next door have ground elder! I have to dig it up by hand and then put it on the paving to dry out and die!
its not too bad to dig out though... quite satisfying when you get to tug a main root out... it doesn't break up or fragment!
