Taxonomical history

Date	Event
1847	This species was first described by Miles Joseph Berkeley using the specimen collection from Ceylon (now Sri Lanka). He named this species Agaricus albuminosus.[2]
1887	Pier Andrea Saccardo renamed this species Lepiota albuminosa.[3]
1891	Otto Kuntze renamed this species Mastocephalus albuminosus.[4] Mastocephalus is a synonym of Leucocoprinus.
1912	Thomas Petch identified the original specimens as termite mushrooms, renamed this species Collybia albuminosa, and listed Collybia eurhiza (now Termitomyces eurrhizus) a synonym of this species.[5]
1927	Casper van Overeem renamed this species Gymnopus albuminosus.
1941	Roger Heim renamed this species Termitomyces albuminosus.[6]
1969	David Pegler and R. W. Rayner commented that the identification by Petch (1912) of the original specimens failed to address their microscopic morphology.[7]
1972	Pegler renamed this species Macrolepiota albuminosa.[8]
1977	Heim redescribed Termitomyces albuminosus using specimens from India.[9]
1979	Krishnamoorthy Natarajan examined the 1977 specimen collection, and newly described a species Termitomyces heimii to accommodate these specimens.[10]
1986	Pegler listed Macrolepiota albuminosa a synonym of Leucocoprinus cepistipes.[11]
