Clarifying the typification of Tulostoma dumeticola (Agaricaceae, Basidiomycota)

Tulostoma dumeticola Long is an American gasteroid species described based on collections from Southern Brazil. Specimens were first identified as T. verrucosum Morgan by J. Rick (known as the father of the Brazilian Mycology), but then, described as a new species years later by Long (1947). According to Wright’s (1987) monograph on the genus, the type specimen of T. dumeticola was kept at BPI under the number 704401 and isotypes were deposited at FH and NY (Thiers 1997). Wright’s (1987) statement about the supposed type was later followed by Calonge & Carranza (2003), who even annotated the specimen. In 2008, the supposed type specimen of T. dumeticola (BPI 704401) was requested as a loan from Herbarium ICN (Brazil), but unfortunately, it was lost during shipping. Therefore, the selection of a lectotype would be necessary.
