Xylaria corniformis é um ascomiceto carbonáceo em forma de maça que produz estrómalos negros, firmes, em forma de chifre ou galho de veado, sobre madeira em decomposição em habitats florestais tropicais e subtropicais. É um decompositor saprotrófico de madeira que contribui para a degradação da lignocelulose nos ecossistemas florestais. Classificado como Em Perigo, as ameaças incluem o desmatamento tropical e a perda de habitats de floresta antiga.
