As I mentioned in a longer article on MuhsroomTalk, this seemingly gemmatoid Amanita is actually in the Amanita muscaria clade. We have 4 collecitons of it already and I recognize it in the field now. This is one of the 4-5 members of the yellow Amanita group in California that have been referred to A. gemmata gr.

Elsa, I’m not sure

that I understand exactly what you are asking, especially the first part of your questions. If you are asking for basic information about microscopic features and how to use the microscope, I suggest getting a copy of “How to Identify Mushrooms to Genus III” by David Largent et al. Also, there are online sources such as.. http://www.first-nature.com/fungi/facts/microscopy.php As far as taking pictures through the microscope, there are several approaches but the easiest method, which I use, is to simply get a relatively small and inexpensive point and shoot camera and hold it up to the eyepiece of the microscope. I’m simplifying a little but that is the basics.

Can you explain me the characteristics that must have a microscope to see the spores and how to prepare the sample? And how do you photograph it?
