Copying some stuff for the moss from wikipedia: Physcomitrella patens is an early colonist of exposed mud and earth around the edges of pools of water.[2][3] P. patens has a disjunct distributionin temperate parts of the world, with the exception of South America.[4] The standard laboratory strain is the 'Gransden' isolate, collected by H. Whitehouse from Gransden Wood, in Cambridgeshire.
