Document Summary
You need conidia in order to do identification. They are asexual spores that are needed for the fungus for reproduction. They can be brown, blue, yellowish, or white when seen macroscopically. They"re (cid:374)or(cid:373)ally produces at the tip or sides of hyphae. They can break free of the hypha, dispersed, and then they grow to form a new hypha: this is how they asexually reproduce. To find where the new conidia are being formed, look for non-random patters: they can be formed at the tip of the chain, or the base. Rust extracts food from a living host, which makes them biotrophs (extract nutrients from living host cells: host: i(cid:374) this case, it"s a pla(cid:374)t that is a source of (cid:374)utrie(cid:374)t. In our petri dish for example, we cannot have any of this species living there because there"s (cid:374)o pla(cid:374)t, a(cid:374)d therefore (cid:374)o host to gai(cid:374) (cid:374)utrie(cid:374)ts fro(cid:373)
