Most species are described, illustrated and keyed out in the monogograph written by Janusz Blaszkowski in 2012. You can find details here:

Hello, until now we don't have a key for Glomeromycota. In some papers you can find a key for ornamented species of Acaulospora or Scutellospora (lato sensu). Maybe this web site can help you: http://schuessler.userweb.mwn.de/amphylo/

 You can download the species publications. If you need some help, just keep in touch.

I am agreed with you , Camila. I have also downloaded the original articles of the species. For more illustration you may follow the link, http://www.zor.zut.edu.pl/Glomeromycota/

Manual of Schenck  and Perez, 1990 is the foundation for morphological identification

INVAM is also good mentioned by Beatriz.

I recommend this link
