In the framework of collecting and identifying of larger fungi of Iran, specimens of a club fungus were collected from Sangdeh forests (Mazandaran province) in autumn ۲۰۲۲. Specimens were identified as Macrotyphula fistulosa (Holmsk.) R.H. Petersen (Agaricomycetes, Typhulaceae). This is the first report of a species from genus Macrotyphula in Iran. Morphological characteristics of specimens are as follows: Fruitbodies long-cylindrical, simple clubs with rounded, blunt or mitriform tips; solitary to gregarious, ochre to light brown in color; ۷–۲۵ cm high and ۵–۸ mm broad in tip; fruiting on small pieces of rotting wood. Spores white in prints, lacrimiform (teardrop-shaped), smooth, ۱۰–۱۵ × ۵–۸ µm, hyaline, inamyloid. The species apparently has widespread geographical distribution; Europe, and United States.
