Lab 5: Conidiating Fungi

Conidiating Fungi

Objective

The major objective was to prepare slides of conidiating fungi and observing condiating fungal structures under  a microscope.

Materials and Methods
Fungi samples from various conidiating fungi were taken from plates and used to make slides using the squash method.
Slides were then observed under a microscope

Results
          
                                                               Pestalotia spp conidia



                                                         Alternaria brassicola conidia


Thielaviopsis basicola conidia
 

                                                             Thielaviopsis basicola conidia attached to conidiophores



                                                            Apergillus niger conidiophores




                                                           Epicocum spp conidia




                                               Monilinia fruiticola hyphae




                                                                Fusarium graminearum conidia



Curvularia spp conidia
 

 

                                                            Curvularia spp conidia


                                                     Rhizoctonia solani hyphae



                                                       Colletotrichum cocodes conidia





                                                             Colletotrichum cocodes conidia

Discussion
For most conidiating fungi, it was possible to observe dinstict structures that are associated by that fungi. Such distinct structures can easily be used to identify a a fungi. Caution must be taken to avoid identifying fungi wrongly as some do have stucture which look like from a distant.

Conclusion
Conidiating fungi can be identified on the bases of structures such as conidia , conidiophores etc, however use of a classification keys is importani in confirming their true identity.

  1. This is quite good Maxwell. Your pictures do a good job of showing the relevant structures, thet would be even better if you took them at higher magnificaiton. -Shaw
