The largest Xylaria fruiting bodies I have seen, with a 25 cm stroma length. They were apparently fruiting from decaying roots of a large, dead Ceiba pentandra tree. These are very similar in stromal texture and spore size/morphology to X. kegeliana, except for the absence of a germ slit that spirals (straight to slightly oblique in this collection)
Attached to a log on the floor in advanced process of decomposition. A good amount of palm trees around. The fungi fruit was swollen, spongy. I opened one of them to observe, it was gelatinous, blakish and had a tangy citrus smell to it.
Found by @graysquirrel on downed branches and twigs of Quercus agrifolia.
