Observation - White filament fungi?. Description: Hi, just returned from a holiday on Dartmoor where we found this strange growth on birch twigs on the ground. There was quite a lot of it spread around a small area of woodland. It was snowing and very cold. I couldn't see it growing on the trees. Thanks
