 ===== Description =====
-Phoma (Phomopsis) is a fungal disease known to affect cacti, including *Trichocereus* species. It presents as a pathogen of concern that can compromise the health of the host plant. While specific visual symptoms, lesion types, and progression patterns on the epidermis or ribs were not detailed in the community discussion, identification typically relies on diagnostic observation of fungal spread.
+Phomopsis is a fungal disease that presents as uniform circular patterns with raised brown to tan lesions, often surrounded by reddish-brown and distinctly defined border. Small black pinhead dots are pycnidia fruiting structures where the spores are produced. Phoma rarely grows to large size and is not necessarily centered on areoles. Can be an aggressive pathogen and thrives in humid, warm and wet conditions. 82 degrees F is optimal for growth.
-===== History & Origin =====
-The identification of this pathogen within the community was documented in April 2026, stemming from an infected specimen presented by grower Itzel Estrella. The fungal infection was identified as Phoma/Phomopsis by community member Dushi Kaunt.
