Because of its chosen substrate - dung and bones - Tetraplodon can disappear from a known site after a few years. 

Tetraplodon mnioides is generally rare in lowland areas and has now almost disappeared from south-eastern England.

It was recorded from Thursley Common in 1970, and Bagshot Heath in Surrey in 1975, and was last recorded from Hampshire at Yateley Heath in 1986. 

During the 1990s, there were no records of this moss from the area.  But in 2001 one patch of T. mnioides was re-discovered on Thursley Common. 

Unfortunately, following a devastating fire in 2006, Tetraplodon mnioides has now disappeared once again from Thursley Common.
