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.

Penicillium digitatum is a species of fungus in the Ascomycota phylum. It is commonly found in soils and decaying organic matter, and is known to cause green mold on citrus fruits. In East and Central Texas, P. digitatum has been isolated from various environments, including soil, plant debris, and infected citrus fruits, particularly in the Rio Grande Valley and the Blackland Prairie regions. The fungus thrives in warm and humid conditions, making these regions suitable for its growth and development.
Discarded orange peel covered by green mould fungus Penicillium digitatum on Winters Bayou Trail in Sam Houston National Forest. Cleveland, Texas, October 16, 2021
Lone Star Hiking Trail, San Jacinto County, Texas, 77328, United StatesObservations of the fungus Penicillium digitatum in East and Central Texas revealed its presence on discarded citrus peels. On Winters Bayou Trail in Sam Houston National Forest, Cleveland, Texas, an orange peel was found covered by a green mould of Penicillium digitatum on October 16, 2021. This sighting indicates the fungus's ability to thrive in the region's environment. The fungus likely grew rapidly on the nutrient-rich orange peel, suggesting that it can capitalize on available organic matter. Similar observations may be expected in other areas with suitable substrates and environmental conditions, highlighting the adaptability of Penicillium digitatum in East and Central Texas. This fungus is commonly associated with post-harvest decay of citrus fruits, underscoring its potential impact on local agricultural produce. Its presence in natural settings also points to its role in decomposition processes within these ecosystems.
