Alsophila brausei, synonym Cyathea hunsteiniana,[1] is a species of tree fern endemic to eastern New Guinea, where it grows in rain forest at an altitude of 1300–2000 m. This species has a slender, erect trunk up to 1 m tall and about 3 cm in diameter. Fronds are bipinnate and approximately 1 m in length. Scattered scales cover the stipe. They are dark brown in colouration and have a broad paler margin and fragile edges. Round sori are borne one or two per fertile pinnule segment. The sori are protected by deep, firm indusia that are cup-like in appearance.[2]

Large and Braggins (2004) note that Alsophila brausei is very similar to , but differs in the lack of scales on the fronds.[2]

Tryon transferred this species to the genus Alsophila, he published the replacement name Alsophila brausei, with the specific epithet brausei commemorating Guido Georg Wilhelm Brause (1847-1922), who had originally described it.[2]
