New distribution record of Roridomyces cf. phyllostachydis (Agaricales: Mycenaceae), a bioluminescent fungus from Namdapha National Park, Arunachal Pradesh, India

Abstract

Nocturnal surveys conducted in Namdapha National Park of Arunachal Pradesh (India) in April 2022 led to an opportunistic encounter with bioluminescent fungi. Based on morphological characteristics and photographic comparisons from published literature, we have identified the species to be Roridomyces cf. phyllostachydis, a glowing mushroom that has previously been described from two different districts of Meghalaya (East Khasi Hills and West Jayantia Hills). The glowing stipe surface without the glowing pileus distinguishes this species from other bioluminescent fungal species found in India. Our observation of Roridomyces cf. phyllostachydis marks a new distribution record from the state of Arunachal Pradesh.
