The Allogona ptychophora snail is found mainly in areas of debris, such as leaf litter and rocks.  A subspecies, Allogona ptychophora ptychophora, was found most commonly in boulder piles and areas of talus (Frest et al, 1997).  A talus environment is one that could be described as having rocking slopes, with and occasional small tree.  Rocks tend to be covered in moss, and they tends to be small vegetation closer to the ground.  To the left is a picture of a oak-birch talus, which we can assume to be similar to the habitat of Allogona ptychophora.  Since the subspecies is part of Allogona ptychophora, we can say that their specific habitat would be very similar (Frest et al, 1997).  This habitat would seem ideal for a snail that
feeds on fungi.

Allogona ptychophora
is a terrestrial snail that is spread across the Northwest United States and into Canada (Turgeon et al, 1998).  It is found most commonly in the eastern parts of Washington (Turgeon et al, 1998).  It has been found in the Canadian province of British Colombia, Idaho, Montana, Oregon, and Washington (Turgeon et al, 1998).  Below is a map of the distribution of Allogona ptychophora.
