I didn’t even notice the mature tube slimes beside the immature ones when taking the photos so I apologize that I don’t have up close ups of them. Found on a dead log in a coniferous forest, along a disturbed trail. When I touched it, it oozed slime.
Growing on a buried conifer stump.
Mild smell and metallic taste.
I like the German book id which says this is part of the L. carestiae-ovideum Komplex
