Differences between Rhizopus and Mucor

Sl.No.	Rhizopus	Mucor
1.	Mycelium is distinguished  into stolons and Rhizoids	Mycelium is one kind of hyphae
2.	Rhizoids are present	Absent
3.	Stolons are Present	Absent
4.	Food material is absorbed by Rhizoids	Absorbed by mycelial surface
5.	Sporangiophore are un branched	branched
6.	Sporangiospore are easily blown by wind	Columella bursts and Mites bring about dissemination
7.	Contamination in lab culture	Not contaminated
8.	Sporangiophore are arise only from the junction of Rhizoids and stolons	` Sporangiophore may arise at any place
9.	Trisporic acid B & C are produced	Trisporic acid A is produced
