Taxonomy
It was first described by mycologists Morten Lange and Alexander H. Smith as Coprinus sassii in 1952.{{cite journal |vauthors=Lange M, Smith AH |year=1952 |title=Species concept in the genus Coprinus |journal=Dansk botanisk Arkiv |volume=14 |issue=6 |pages=1–164}}
In 2001 a phylogenetic study resulted in a major reorganization and reshuffling of that genus and this species was transferred to Coprinellus.{{cite journal |author=Redhead SA |first1=Scott A |author2=Vilgalys R |author3=Moncalvo J-M |author4=Johnson J |author5=Hopple JS |author6=Hopple, John S |author7=Johnson, Jacqui |author8=Moncalvo, Jean-Marc |author9=Vilgalys, Rytas |year=2001 |title=Coprinus Pers. and the disposition of Coprinus species sensu lato |journal=Taxon |volume=50 |issue=1 |pages=203–241 |doi=10.2307/1224525 |jstor=1224525}}
The species was known as Coprinellus sassii until 2020 when the German mycologists Dieter Wächter & Andreas Melzer reclassified many species in the Psathyrellaceae family based on phylogenetic analysis.{{Cite journal |last=Wächter |first=Dieter |last2=Melzer |first2=Andreas |date=2020-11-01 |title=Proposal for a subdivision of the family Psathyrellaceae based on a taxon-rich phylogenetic analysis with iterative multigene guide tree |url=https://doi.org/10.1007/s11557-020-01606-3 |journal=Mycological Progress |language=en |volume=19 |issue=11 |pages=1151–1265 |doi=10.1007/s11557-020-01606-3 |issn=1861-8952|url-access=subscription }}
