'fungus-like' originates from the word 'fungus,' which comes from Latin 'fungus,' meaning 'mushroom.' The suffix '-like' is used to indicate resemblance.

The term 'fungus' was adopted into English from Latin, and the suffix '-like' has been used in English since the Middle Ages to form adjectives indicating similarity.

Initially, 'fungus' referred specifically to mushrooms, but it has expanded to include a wide range of spore-producing organisms.
