I have isolated some fungi from infected Tomato leaves. I am in doubt is that Mucor or Rhizopus. In media PDA it producing some-how colourless mycelial growth with black dot on the tip.
Hi , the major different between Rhizpous and mucor is in the Rhizopus the branch point of the sporingophor has a rhizoid in Muucor is absent,
see the attached file for the Rhizopus
Looks like Mucor to me. I suggest that you please show us older cultures.
In my opinion these microphotograpies look like Mucor spp
In my opinion it was Mucor, but you must show us older cultures. But i thnk that is a Mucor.
You should to check the presence or absence of the rhizoids at the attach point of the sporangiophores becuase this photos do not confirm this point. In case of the absence, it is mucor.
Mucor differs from Rhizopus in not producing rhizoids. Rhizopus is recognized by the presence of well developed rhizoids situated at the point where sporangiophores are attached to the stolons. In contrast to Mucor, Rhizomucor and Absidia, the sporangiophores are often unbranched and grouped in tufts. I hope this is helpful for you. Best, Maria
In my opinion it is Mucor spp. but you should to check if rhizoids are present what is typical for Rhizopus. In case of Rhizopus sporangiophores often are grouped in tufts and mature, opened sporangium often has typical shape. Please, see the attached file for the Rhizopus.
Respected Medam
Please send photograph of Rhizoid and stolon of fungus on the base identified and differentiation of both fungus
yes I agree with all, you should compeare between more than 3 picture and the photograph should be content complete of fungi with mycellium and Rhizoid and stolon of fungus on the base for make identified and differentiation of both fungus
Dear Priyanka Roy,
as far as I can see the fotographs show only the level on the suface - as said by others already introduce pictures of the mycelium within the growing medium - quite easy scrape of the surface mycelium cut our a piece of the medium - squeeze it carefully and make fotos what you find. Also from my experience it looks very much like Mucor species. But by the approval from the basis the organisms you can easily judge on the question - the root like structures are easy to identify. Best wishes - Heinz-W.
Dear Priyanka,
from the third image, seems to me clearly show one sporangium of Mortierella and not of Mucor or Rhizopus
It is hard to say from the pics, but Mortierella has branched conidiophores. Alternatively, an easy way to be sure that you are facing Rhizopus is because of the presence of rhizoides in the mycelia. A kind of roots in the mycelia just beneath the conidiophore. This structure attaches the fungus also to the top of the Petri plate.
Mortierella not always is branched, the Rhizopus, in addition to having one large and rhizoids sporangium which are not seen in the photographs, is always colored and with larger spores. Perhaps it would be good to have pictures not colored and that will bring other structures that may be present.
You must grow this fungi by slide culture method, if there is no rhizoid and stolon, it is mucor
Please explain this picture, I think I see some septa in this picture!!!
'Unseptate mycelium' does not mean that the organism never develops septae. I is rather typical for zygomycetes to produce septae below reproductive structures, in this case below mitosporangia.
I agree completely with this comment. Additionally one can find septae close to mycelial damage or functional impairment. To differentiate Mucor from Rhizopus species one needs the opposite part to the fruiting body: the rhizoid like basis of Rhizopus to distinguish this from Mucor sp. Good luck! Heinz-W.
Pl see in microscope if stolon and Rhizoid present and opposite development of spoangiophore , it indicate Rhizopus
Mucor
