Cap/Head attached and inter grown with stalk, irregularly wrinkled, with hollowed, irregular chambers,
Hymenium layer(outside surface)
brown-cinnamon brown or ocher brown when young.
Stalk/Stipe
large, with many small chambers that are lined with a white cottony surface when young, lighter then cap/head almost pallid white when young becoming palid brown with age or when wet,
Spores with one large oil drop in the middle and 2 small ones at each end, some times with very small blunt nobs at each end with age,
Oder pleasant, not as strong as G. esculenta

Found on the ground or in very rotten stumps, in the early spring,

Can be confused with Gyromitra esculenta
differs in that the stalk is not usually as large and chambered,
stalk surface of Gyromitra esculenta slightly turns pinkish with KOH,
while Gyromitra gigas may turn slightly yellow,
the easiest way to tell them apart is by the spores, Gyromitra esculenta only has 2 small oil drops at each end of the spore and may also have projections out of the end,
and this species (Gyromitra gigas) has large central oil drop as well as two smaller ones on the ends.
