Sentence:  In cases where a name-bearing type exists but does not show features needed for conclusive identification with a particular species circumscription, for example, one lacking spores, an interpretative type, an <WSD>"epitype</WSD>", can be designated to supplement information evident in the name-bearing type. <WSD>Epitypes</WSD> are increasingly being designated in mycology today for sequenced material where DNA has not or cannot be recovered from the name-bearing type. 
Meaning of the word marked with <WSD> tags:  An additional, clarifying type (specimen or illustration) of a species or lower-order taxon, provided when the holotype and paratypes from the original classification are demonstrably ambiguous or insufficient.
