"Les Crossan" So that's what it's called! That AC with the strange bases
are rather rare.
I thought 'lacunosis' was 'net structure' ??

I've got one or two - but not quite in that detail as these were webcam
captures.

Les,
my old MO glossary says " Lacunosus...having holes.....cloud
...layers...marked by more or less regularly distributed holes....often
arranged in....a net or a honeycomb".It does not list reticular.
However, on the basis of Scorer and the two papers I go with reticular. I
emphasis the photos don't bring out the 3D structure and the point that this
is a phenomenon related to mammatus (which lacunosis is not),
regards,
David

It's something I've not seen very often - and know nothing about. I'll
keep an eye open though for any strange structures in Ac though.
