Protubera maracuja is a species of fungus that produces small, yellow to orange, globular to pyriform fruiting bodies. In East and Central Texas, it has been found growing on the ground in wooded areas, often associated with oak and pine trees. The fungus typically fruits in late summer to early fall, and its distribution in the region appears to be scattered and localized.

AI-generated summary of observations
Protubera maracuja, possibly Glomus or Endogone, was observed in East and Central Texas on wet sandy soil under half-burnt fallen pine or oak trees. The mushrooms were small, with a yellow woolly surface and a darker brown brain-like interior. They were found in a relatively wet area with oaks, large pines, and Yaupon surrounding them. The gasteroid fungus was very soft and had reddish umbilical cords at the bottom. Some specimens were half-broken, revealing their internal structure. The largest size observed was approximately 1 cm. The mushrooms were often covered in yellow wool and were found in small soil cavities under the fallen trees on the Stubblefield section of the Lone Star hiking trail in Sam Houston National Forest.
