  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.
