Seasoned forager New to Georgia

I am sure you have already checked out the "Atlanta Area Morels" thread - that has most of what I would say: try rich but well-drained floodplains with a mature overstory - often areas that are overrun with privet. Trillium and trout lilies are some good indicators of the type of habitat, but overall probably have a wider habitat range than morels, so you won't find morels everywhere trilliums are found. Morels seem to associate with tulip poplars in the southeast. As for timing, I think the best tack is to just keep tabs on these forums and the morel progression maps available elsewhere on the web. A Florida resident, I generally make one trip a year to middle Georgia to look for morels, typically sometime between the last weekend in March and the first or second weekend in April. This year, with the early spring, we tried in mid-March, just before things turned cool again, and had very limited success with early black morels, but found no yellows.
Best of luck.
