Morphology
Astreus + hygrometricus
This is a Latin binomial (scientific) name where the second element 'hygrometricus' is not a standard English word (marked as not found) and the construction follows taxonomic naming conventions rather than everyday compositional rules. Even if the parts have Latin roots, a B1 learner who knows the listed constituents would not be able to infer the meaning 'a species of earthstar fungus', so the term is effectively idiomatic/opaque for learners.
Etymology
Astreus hygrometricus was named for its star shape and for how it reacts to wet or dry ground: Astreus looks like a star and hygrometricus means 'measures moisture'. Its star-like rays open when the soil is wet and curl up when it is dry, so the name helps you remember why the fungus reacts to moisture.
