Etymology: < scientific Latin rivulosus (1773 or earlier as specific name in zoology, 1803 or earlier as specific epithet of a lichen) < classical Latin rīvulus small stream, rivulet, small channel (see rivule v.) + -ōsus -ose suffix¹. N.E.D. (1909) gives the stress as rivu'lose.

Chiefly Mycology.

Marked with irregular sinuous lines or furrows resembling rivers marked on a map.
