Slimy Fungus on gravel

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.

    Try spraying with a moss and algae killer, available at garden centres. That should get rid of it.

  • 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?

    I think you've got a slime mould.  They usually grow on lawns but you must have some sort of organic matter in your gravel - leaves or something.  Google comes up with this advice http://ourohio.org/index.php?page=1323

    Good luck.

  • 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

    Can you post a photo or two?  That might help.

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

     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.

    Thanks.

     

  • I have exactly this growing on a concrete path. It is a real pain and very slippery to walk on. I thought it was a slimemould but have been unable to identify the actual species- I agree with you it doesn't look like any of the pictures I can find on the 'net. I am scraping it off with a spade at the moment but if you find a better way to exterminate it I would be grateful to know.

    thanks

  • 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.
