purpose of book would be for identification
thanks

You might try this one./Link below/

George Schenk wrote a book about Mosses for Gardens, but not sure it would be that helpful in identifying mosses in a given area.
There are probably some scientific papers and books covering Mosses and Bryophytes of PA. You might have some success in a search of your local library. The Penn State library would probably be the best source of information, If you are over in that direction.
Good luck!

Here is a link that might be useful: Outstanding Mosses & Liverworts of Pennsylvania & Nearby States

I looked at the library and I went to the conservation district office. Neither one have any books about moss native to NE pa.
Thanks for the link, I'll check it out.

The site below has a Moss Growers Handbook listed under "External Links" near the bottom of the page.
This is a downloadable PDF document that provides keys to moss identification. Only line drawings/sketches are provided, but may be useful, if no other photographic information is available.
Good luck!

Here is a link that might be useful: Moss

I do not have any favorite moss books but I use the internet to construct whatever documentation I need in my studies. The link below will probably list many of the species found in your area. Why I am sending this is that the list of references may be what you may want to research. It would be a good start to use at a library search.

I second razorback's link: "Outstanding Mosses & Liverworts of Pennsylvania & Nearby States" by Susan Munch. 90 pages, color pics, pen & ink drawings and a full description of all bryophytes in our area. The book cover says you can email the author at susanm@alb.edu to buy a book.

Im calling the book store to see if I can order the book by George Schenk. Thanks

Oh the book is by susan munch, I was confused.

The George Schenk book is very useful, and he is a fun writer to read. I recommend this very highly. I also downloaded "The Moss Growers Handbook" which someone kindly sent a link for - I think it went to the Royal Horticultural Society. If you can't find it let me know.

Ok little toad thanks!Ill check out the george schenk book also.
