Explanation:

Agaricus is a genus of mushrooms containing both edible and poisonous species, not an bio fertilizer.

Nostoc is a genus of cyanobacteria found in various environments which is used asbiofertilizers. Nostoc fixes atmospheric nitrogen into ammonia, which may then be used or converted to a form suitable for plant growth.

Spirogyra:- The algae grow on their own in the rice fields, but all of them are not beneficial to crop. The green algae likeSpirogyra compete with the crop for nutrient and reduce tilering in the crop.
