Remarks (public):According to present knowledge A. angustifolia is one of the most widespread species of Astrosporina in Indomalaya and Australasia. The fungus occurs in the oak forests of Papua New Guinea, Java and Sabah. Variable in morphology and colour this species is readily recognized in the field due to the following peculiar characters: innately fibrillose to subsquamulose pileus,
very narrow and densely crowded lamellae, slender cartilaginous and pruinose stipe (with a small marginate bulb at the base) and spermatic odour.
