Cyathea fuliginosa is a species of tree fern native to the islands of Luzon, Biliran and Mindanao in the Philippines, where it grows in forest at an altitude of 640-2400 m. This tree fern has an erect trunk up to 5 m tall or more. Fronds are bi- or tripinnate and 1-3 m in length. The stipe is warty and may also (or instead) have short spines as well as many scattered scales towards the base. These scales are dark, glossy and have fragile edges. Sori occur near the fertile pinnule midvein and are protected by firm, dark indusia.
