We present a discussion of black 2-branes coupled to the fields of the universal hypermultiplet of ungauged N=2 supergravity theory in five dimensions. Using a general ansatz dependent on a spherically symmetric harmonic function, we show that there are exactly two such solutions, both of which can be thought of as arising from the dimensional reduction of either M2- or M5-branes over special Lagrangian cycles of a Calabi-Yau 3-fold, confirming previous results. By relaxing some of the constraints on the ansatz, we proceed to find a more general solution carrying both M-brane charges and discuss its properties, as well as its relationship to Euclidean instantons.
