I went for a walk in the field and found this strange deposit clinging half way up some blades of grass. The picture says it all - a strange white cellular substance, with open cells rather than bubbles like you'd get with cuckoo spit. It was wet to the touch. I took a photo and asked my friend Chiron for assistance in identifying it. Although he had also never seen anything like it, he quickly found out that it is a slime mould - specifically "dog sick slime mould". Well I never.
