Ptychostomum turbinatum, also known as topshape thread-moss or pear-fruited bryum, is a species of moss found in continental Europe and the US.[1][2] The species became extinct across the British Isles in the 1940s according to the Species Recovery Trust and in 2001 according to the IUCN, and it has not reestablished since.[3][4][5]
Splachnobryum kieneri is listed by the USDA as a synonym.[6]
