Extract from Wikipedia article: Penicillium digitatum (/ˌpɛnɪˈsɪlɪəm/digitatum/) is a mesophilic fungus found in the soil of citrus-producing areas. It is a major source of post-harvest decay in fruits and is responsible for the widespread post-harvest disease in Citrus fruit known as green rot or green mould.In nature, this necrotrophic wound pathogen grows in filaments and reproduces asexually through the production of conidiophores. However, P. digitatum can also be cultivated in the laboratory setting. Alongside its pathogenic life cycle, P. digitatum is also involved in other human, animal and plant interactions and is currently being used in the production of immunologically based mycological detection assays for the food industry.
