Growing Penicillium digitatum on Todd ( an orange )
Under general environment
 |
| As you can see the green parts indicates the development of conidiophores and as well as the fruiting bodies which carry the spores |
Under general environment, an orange named Todd was left for a while infront of a window a couple of days and symptoms of fungal infection was seen ( white color ) as the beginning, it indicates the sprouting of spores to hyphae which then forms a network of mycelium and later on forms the fruiting bodies which carry the spores at that time it becomes green in color.
The mold scientific name is Penicillium digitatum
The main causal agent of fruit-rot to citrus fruits ( e,g, orange as in our case) the green mold disease, also it is a major post-harvest disease which should be taken into consideration when harvesting our crop.
A mesophilic fungus which prefers temperatures between 15*C-45*C, of Division: Ascomycota
Following a strict means of clean and sanitized storage, handling and packaging can ensure the least infection, removal of any infected plants quickly before the mold grows and infects other fruits comes in handy, applying specific fungicides in particular concentrations and much more from chemical and biological controls can be found in the following website:http://www.plantwise.org/KnowledgeBank/Datasheet.aspx?dsid=39570
Culturing it, due to the limited resources I have since of my inability to afford tools for culture media, I have used Gelatin, I bought a strawberry Jelly, prepared it and inoculated a sample of the fungi in it and after 5 days leaving the petri dish in room temperature, results were:

| My very first culture media |
This was Todd after a week from the last picture shown

| Needed to be contained |
