M. albopurpureus is a part of the section Globulares of the genus Marasmius.^[1] This species has a grooved mushroom cap, white to purple in color, from 10–20 mm (0.4–0.8 in) wide.^[1] It also has cream to purple gills (lamellae), and has clear basidiospores that are 20–25 x 4–6 μm.^[1] The wrinkled, hollow stipe is 63–90 mm (2.5–3.5 in) tall, purple towards the top, and browner towards the bottom.^[1] This stipe differentiates it from the similar species in China, M. campestris (which has scales on the stipe)^[2] and M. subpurpureostriatus (which has a frosty pruina on the stipe),^[3] from the similar species in Japan, M. purpureostriatus (which has a purplish-grey to reddish brown stipe), and from the similar species in India, M. indopurpureostriatus and M. odoratus (which both have much longer stipes).^[2]
