From the edge of a lawn near an old apple tree, appearing as terrestrial. The spore ornamentation points to Gyromitra leucoxanrha. The flaps seen (one at each pole) are squared-off and many are concave along the outer edge. iNaturalist calls this species "fishtail cup", apparently a reference to the spores.
However, the fruit bodies are more pezizoid in shape than the typical G. leucoxanthus, and the projections on the spores (one at each pole) are perhaps more rectangular with a less prominent central depression along the outer boundary. Michael Beug suggested the possibility this is G. persicula. It's a relatively new name; I don't know if it has been published.
Except for the last two spore photos (which are H2O mounts) all others are mounted in cotton blue. The last photo shows two small fruit bodies that I did not harvest. Photos were taken over the period 04-30-2024 through 05-02-2024, exxcept the last in situ that was taken 05-06-2024. 
Preserved material was sent to Andy Miller for possible sequencing.
