Hello David and List,

Right, well observed. Several lunar meteorites are
definitely "vesicular" and have a greenish tint!

Dhofar 025: "schlieren and vesicles are abundant"
Dhofar 026: "vesicles are abundant"
Dhofar 081: "schlieren and vesicles are abundant"
Dhofar 280: "schlieren and vesicles are abundant"
NWA 482: "glassy and vesicular melt veins and melt
                  pockets"

As for descriptions of the crusts of lunar meteorites:

DaG 400: "the meteorite is partly covered with a brownish fusion crust"
Dhofar 081: "A brownish gray stone of 174 g covered by fusion crust"
EET 96008: "this meteorite is covered by a black glassy fusion crust."
MAC 88104: "Both specimens have thin gray-green fusion crust"
MAC 88105: see 88104
QUE 93069: "Thick gray-green frothy fusion crust covers the top while
                    thin granular medium olive green-brown fusion crust
                    covers the bottom."
QUE 94269: "One side of this flat stone has thick, gray-green, frothy
                    fusion crust."


Best wishes,

Bernd
