From Latin 'guttula' (small drop) + the adjectival suffix '-ate' (having the quality of). This describes something decorated with or appearing to have tiny drops.
Many fungi, leaves, and insects are described as 'guttulate' in scientific literature—a guttulate toadstool has drops of darker color on its cap, like it's been spattered with paint.
