Bad fungus/disease ?

Asked June 2, 2018, 1:39 PM EDT

Probably dumb of me, but for years I have been dumping pine cones at the edge of a garden as sort of a trench/edge for weed control. It is on the north side of house. Now periwinkle vinca has spread over it. Was trimming up some vinca and noticed lots of pine cones covered in fungus, especially since been so moist. Is this harmless or do I need to remove all pine cones immediately?

Those pine cones are not going to just disappear. It would take years and years for them to compost. In the meantime mildew and other fungi will probably grow in them. I would remove them. They also make great hiding places for mice and other vermin.
