The Fusarium nivale fungus has wrought destruction from Surrey to Scotland, with Northumberland and Yorkshire particularly badly hit.The nationwide blight came to light as forecasters warned of 'another blast' of winter today.
Up to two inches of snow will fall across much of the country, with central England and south-east Wales being the worst affected.
The wintry weather will continue until late tomorrow and may well cause widespread disruption to commuters returning home in the Friday evening rush-hour.
The Met Office has issued a weather warning for a 60 per cent chance of heavy snow affecting South West England, Wales, western and eastern parts of the Midlands today, with two inches expected widely and up to four inches on higher ground.
A further weather warning has been issued for widespread icy roads across the Midlands, Eastern England, London and the South-East.
Tim Thorne, from the Met Office, said: 'It's great news for the kids on half-term. But for everybody else the novelty of snow this winter seems to have worn off. The snow will start off in the south-west and move up over the Midlands where we are expecting it to linger.

'It will then hit eastern parts by Friday and could cause some disruption to roads and rail connections. February is generally the coldest month so it shouldn't come as too much of a surprise.
'Many parts are likely to see a bitterly cold Friday night.
'We are hoping it will all be over by the weekend when many areas should see some sunshine. It is fair to say it has become something of a nuisance.'
Last month was the coldest January in Britain for 20 years, and February hasn't been a lot better.
Britain's biggest lawn care company, GreenThumb, says the combination of snow and lack of wind have made this year's outbreaks of Fusarium nivale the worst in the firm's 25-year history.
Technical manager Steve Taylor said: 'For grass to survive and stay healthy, you need air to keep blowing across the surface of the plant.
'Snow keeps the grass warm but it suffocates the air and it is the catalyst that allows the disease to take hold and blight your lawn.
'We have been called out to treat cases all over Britain but the east side of the country has been particularly badly hit.'
Tips for prevention include keeping grass well fed during the summer and autumn months to boost its resistance against disease. But last-minute fertiliser feeds in November or December can actually increase the risk of the blight. Lawns should be kept short and dead grass and moss raked out.
If the fungus does take hold, gardeners can call in the professionals for a one-off fungicide treatment.
Aeration, in which a mechanical fork is used to drill small holes across the lawn to encourage air flow, might also be necessary.
In severe cases, re- seeding will need to be carried out.
Rosa Harrison, founder of the London Lawn Care Company, which looks after 360 gardens in the capital, said: 'If you are really worried, call in an expert who will apply a fungicide that stops the damage. 'If you are less worried, wait until your lawn dries out, then rake out the mould and reseed.
'Don't walk on your lawn when it is wet and boggy in case you spread the fungus.'
Tips for prevention also include keeping grass short, reducing the amount of moisture trapped and the risk of the mould growing.
