In 2015, during a visit to Řeka Nature Reserve, an interesting earth tongue fungus was found in a fen meadow. It was later identified as Hemileucoglossum pusillum, a recently described species. Its occurrence on the site was also confirmed in 2021, when abundant material was collected. In the Czech Republic, it is the only known locality of this rare species, previously reported from Slovakia, Norway and Spain only. Its identity was verified both morphologically and molecularly by sequencing the ITS and LSU regions of nuclear ribosomal DNA. Its macro- and microscopic characters are presented and the variability, distribution, ecology and phenology of the species are discussed. A Czech name is proposed for the species.
