I have found a mushroom that I believe belongs to the *Amanita* genus, and I want to use the site's identification key to narrow down its species. Navigate to the *Amanita* (Key) page. Once there, describe the initial steps or questions the key asks to begin the identification process. Also, find and describe how the site explains the term 'mycorrhizal' and its relevance to mushroom identification.
Navigate to 'http://mushroomexpert.com/'. Locate and click on the 'Amanita (Key)' link from the main alphabetical list or the dropdown menu. On the *Amanita* (Key) page, identify and describe the first few questions or criteria presented to the user for identification. Navigate back to the 'The Genus Agaricus' page (http://mushroomexpert.com/agaricus.html) where the term 'mycorrhizal' was linked. Click on the 'mycorrhizal' link (ID 53) on the 'The Genus Agaricus' page. On the 'Mycorrhizal Fungi' page, describe what 'mycorrhizal' means and explain its relevance to mushroom identification as presented on the page.
The agent successfully navigates to the 'Amanita (Key)' page. The agent describes the initial steps or questions of the *Amanita* key, such as distinguishing between species with a volva or ring, or those that bruise/stain. The agent successfully navigates to the 'Mycorrhizal Fungi' page. The agent explains that 'mycorrhizal' refers to a symbiotic relationship between a fungus and the roots of a plant, where the fungus helps the plant absorb nutrients, and the plant provides sugars to the fungus. The agent states that understanding mycorrhizal relationships is relevant to mushroom identification because it helps determine the mushroom's habitat and the types of trees or plants it grows in association with.
