First I will apologise for not taking a pic of this but things at home have been a bit topsy turvy as we had to get the vet out this afternoon, and I got a bit behindhand.
To get on with this, I was cutting the grass out front today and noticed a lot of yellow things growing in amongst the grass. Most are very small still but one or two were bigger. The biggest one was about 2 inches long and curled like a corkscrew. They are all bright yellow, and very firmly 'rooted' to the ground. There are no leaves, it's a single column of growth but I have never seen anything like it before.
What could it be? I have had a look in my 'mushroom & toadstool' book but can't find it.
