Posted on 4 January 2012 by David Sulfur tuft mushrooms on a lawn A fairly common fungus species, and one of the more visible ones now the weather is getting hard, sulfur tufts form large clumps of yellow mushrooms. These were growing on the lawn outside the flats on Merridale Road. Post navigationPrevious post: Horse’s hoof fungusNext post: Woodland clearing, Sutton Park
