Extract from Wikipedia article: Peziza ammophila is a fungus in the cup fungus genus Peziza. It grows on sand dunes and beaches. As it gets older, it comes out from the sand and splits. It grows spring through winter, and in North America. It is cup shaped. The Dutch call these Zandtulpjes, or "sand tulips."

Peziza ammophila is a species of cup fungus that grows on sandy soils, often in association with grasses and other vegetation. In East and Central Texas, it typically fruits in the spring and fall, producing small to medium-sized cups that are 1-4 cm in diameter, with a brown to tan exterior and a pale interior. The fungus is found in open areas, such as prairies, fields, and along roadsides, where the soil is well-drained and sandy. It is relatively common in these regions, particularly in areas with abundant grass cover and low vegetation.

Spore size 14.9 - 15.9 × 8 - 8.7 µm, length to width ratio Q = 1.7 - 1.9.Observations of Peziza ammophila in East and Central Texas revealed the fungus growing in a roadside depression on sandy soil in Bastrop State Park, approximately 1.5 years after a fire had burned the area. The mushrooms were found among dry plants, with side views showing their Ascomycete characteristics. A cross-section of the brown cup fungus was also observed. Spores collected from the site were examined, revealing their morphology. Additionally, spores of different colors were observed in an iodine solution, providing further insight into the species' characteristics. The observations took place on December 25, 2021, in Bastrop State Park, with subsequent spore analysis occurring on February 13, 2022, in College Station, Texas. The findings contribute to the understanding of Peziza ammophila's growth habits and characteristics in this region.
