This is a wood-inhabiting tooth fungus forming highly distinctive and conspicuous basidiomata on trunks and large branches of old (“pluricentenari”) live standing Juniperus phoenicea and J. macrocarpa trees in Italy (Sardinia). Although there are only 3 small areas with fruitbodies known worldwide, there is uncertainty about the extent of its true distribution. The number of mature individuals is estimated not to exceed 600, with no more than 250 mature individuals in the largest subpopulation. A continuing decline is inferred based on the reduction in number of old trees on which it can grow. It therefore qualifies as EN C2a(i).

Abstract
This is a wood-inhabiting tooth fungus forming highly distinctive and conspicuous basidiomata on trunks and large branches of old (“pluricentenari”) live standing Juniperus phoenicea and J. macrocarpa trees in Italy (Sardinia). Although there are only 3 small areas with fruitbodies known worldwide, there is uncertainty about the extent of its true distribution. The number of mature individuals is estimated not to exceed 600, with no more than 250 mature individuals in the largest subpopulation. A continuing decline is inferred based on the reduction in number of old trees on which it can grow. It therefore qualifies as EN C2a(i).
