Trichoglossum walteri is a species of fungus in the family Geoglossaceae. In its current sense, it is considered to be cosmopolitan and as such represents a complex of species worldwide.[2] In the UK, it has been given the recommended English name of short-spored earthtongue.[3] The European species occurs mainly in agriculturally unimproved grassland and threats to this habitat have resulted in the short-spored earthtongue being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.[1]
The species was first described by English mycologist Miles Joseph Berkeley in 1875 as Geoglossum walteri. His description was based on an Australian collection and in its strict sense Trichoglossum walteri may be restricted to the southern hemisphere. The name was, however, adopted for collections with similar microscopic features in North and South America, Europe, and Asia. It seems probable that some of these collections represent distinct species.[1] Initial molecular research, based on cladistic analysis of DNA sequences, supports this conclusion[2] and also indicates that Trichoglossum walteri sensu lato is not closely related to the type species of Trichoglossum, but belongs in a separate genus as yet not formally named.[2]
