VERY LUSH FLAT WEED OVERRUNNING LAWN

Good day all, could somebody possibly identify the weed that is creeping into and spreading across my lawn and advise me how erradicate it. It is lush, flat to the ground,small leaves and very compact. It can be easily scraped off but keeps coming back.

Thank you

 

A picture would make it a lot easier.

 

Thanks Loofa for link, hard to identify from the images seen,Wiil try and get pic, the weed first appeared on the soil and spread, loves shade and disappeared during the hot spell

 

A total stab in the dark here, but it sounds like it might be a Liverwort:

Am I close?

 

Think you're right Kris, the scrape off bit is a giveaway.

 

Liverwort it is Loofah, thank you very much. Is it hard to get rid of and will Verdone extra shift it?

 

Well, it's not a traditional vascular plant, it's more like a lichen. No weedkillers will touch it.
It thrives on poor, shady areas, usually on compacted soil so the best way of tackling it is to change it's environment and growing conditions. Dig over the soil and bring in some plants that will also like those conditions to out-compete it (which probably won't be grass!)

 

Thanks all, the area hasn't been aereated for two years and I have already planned to do it next week.

 

Evergreen feed and weed has done the trick, thanks all
