What are examples of spores on sporangium (like what plant and such would i find them) that i can physically find?

Hi! Spores are produced by sporophyte, or the spore bearing generation. Spores can be found in non seed bearing plants; like liverworts, hornworts, mosses and ferns. In ferns, you could physically find spores on the underside of the frond. These sporangia may clump together as well, to form sori. I hope this helps, let me know if you have more questions!
