Marasmius odoratus—a new jasmine-scented species of Marasmius section Globulares from India

Abstract

Marasmius odoratus sp. nov. is described from Kerala State, India, based on morphological and molecular (ITS) phylogenetic data and is assigned to the section Globulares. Comprehensive description, photographs, and comparison with allied species are provided. It is characterized by a deeply sulcate pileus with grayish red grooves on a pale cream background, a long, pale cream to pale orange stipe, narrowly clavate basidiospores [17–23(–25) × 4–5 μm], a fragrant odor recalling jasmine flower, and a distinctive ITS sequence.

New disease and first report of marasmioid fungus, Marasmius palmivorus (Sharples), causing white root rot in Arachis hypogaea L.

“…In India, about 69 species belonging to the genus Marasmius have been exhibited both as parasitic and saprotrophic life styles (Wilson and Desjardin 2005;Pham et al 2020). Relatively increased attention has been paid to study the diversity of Marasmius species in the southern Indian states such as Tamil Nadu, Karnataka, Kerala and borders of Andhra Pradesh, wherein a total number of 44 species have been reported to occur from this region alone (Natarajan and Manjula 1982;Manimohan and Leelavathy 1987;Adnaan Farook and Manimohan 2015;Sharafudheen and Manimohan 2018). Fries (1822Fries ( , 1829 has identified a new species of Marasmius (M. korthalsii) from the Nicobar Islands for the first time and described them to be whitespored agarics having a tough central stipe.…”
