Morphology

shoestring + fungus

The compound is transparently compositional: 'shoestring' describes a thin, string-like form and 'fungus' names the organism, so a learner can infer it denotes a fungus with thin stringy structures. While a B1 learner might not know the specific species or its pathogenic effects, the core meaning (a string-like fungus) is directly derivable from the constituents.

Etymology

Shoestring fungus comes from the thin, dark, string-like growths it makes underground that look like a shoestring. Those strings are part of the fungus and help it spread along tree roots, so the name refers to a fungus that damages and often kills trees by rotting their roots.
