Have a look. It was clearly visible under my 6x loupe, so it's not a scanning artifact.
Anyone have any ideas why this happens?

Just normal Xtol 1+1. Any idea how the grain pattern came about? Never met a film with such a pattern.

Possibly reticulation from a temperature change between chemicals?
Could the developer have been warmer or cooler than the stop or wash?

looks like reticulation, differences in solution temp should be minimised.

Reticulation is caused by a large temp variation in one of the steps. A few degrees variation will not cause it..
B&W IR film is very unforgiving in developing. The grain pattern can be caused by too much agitation or not enough. Agitation should be gentle for the first 30 seconds and 2 inversions per minute.. Temps should be kept to around 68-72 degrees. Contrary to popular belief a higher wash temp will not cause reticulation unless the wash temp exceeds 95 degrees...and then it shouldn't cause too much problems..
When I want reticulation I usually develope in developer heated to 110-120 then stop with ice water..

Thanks. Haven't seen reticulation till now. This was an old roll of expired Konica IR film, didn't know what to expect. Nice effect though-- not as blotted or splotchy as I'd heard it would be.
