Many thanks for that. Could I ask for an update perhaps in, say, one month. That would be brilliant.

Quick update. I've found reference to this on RHS My Garden forum. It's under "Gardening, Pests and Diseases, Seaweed like sludge in lawn". It appears to be called Blue Green Algae Nostoc Commune. They don't say how to kill it so will post that question on their site.

Many thanks for that. We've now tried the following: Algae/moss killer (Patio Magic), Pathclear, Concentrated bleach, Rock salt, Mould and mildew killer with bleach, Dithane (fungicide), and Roundup. All of these were at double strength. NONE have killed it - you might like to mention that to your local guys.

Of the above, concentrated bleach was the best after covering it very thickly but it hasn't killed it. It definitely doesn't like being covered in a layer of rock salt but, again, didn't kill it. If we can't kill it, then spreading a layer of rock salt would be our best guess to try and, at least, reduce it.

Good luck.

I've now got some of the moss and algae killer recommended above so will try that as soon as the weather is okay. Have used rock salt quite thickly which seems to be having some effect - will need to see when it starts raining again.

 Sorry about the delay. Yesterday after some hot sun it was completely dried to a crisp and blowing away in the wind. After literally two or three hours of rain it is now back again at full strength. It's really weird stuff. Size of fungus in picture is 60mm by 100 mm.

Look forward to hearing your thoughts. If no one has ever come across this stuff should I be contacting Kew Gradens!! They can dig up the whole drive and take it away.

Okay. I'll get it sorted by the end of the week. Thanks.

Many thanks but don't think that's it. I've checked the website that has 23 pages of pictures of slime mouId and not one that looks like it. Also the stuff is growing out of 10 inches of hard core covered by 1 inch of scalpings with the nearest organic matter 5 metres away. It travels by being picked up on car tyres or on feet or being washed into new areas by heavy rain. The smallest bit then seems to grow wherever it falls - as long as it rains, which it's been doing a lot of!

The best description is that it looks like seaweed after the tide has gone out - very wet and slimy. Would really appreciate hearing from anyone who has had experience of this. Thanks.


Really would appreciate anyone contacting who has experience of this

Thanks for that we'll give it a try. Need something quick as it is spreading faster than the triffids did! Anyone else actually got the stuff or know what it's called?

Has anyone come across a slimy fungus which comes up through gravel drives. Brown on top green underneath. Looks like seaweed. Drys to very little in the sun but comes back immediately it rains. Have tried Pathclear and sodium chloride with no success.
