Between October 2nd and 5th, 2007, multiple residents of Libourne in the Gironde department discovered mysterious black circular formations on their lawns that appeared overnight. The rings measured between 5.80 and 10 meters in diameter with a width of approximately 30 centimeters. The precise, large-scale nature of these formations across multiple properties prompted concern among witnesses, leading to official investigations by both the Gendarmerie Nationale and GEIPAN. The case attracted attention due to the sudden appearance of the formations, their geometric precision, and their occurrence across multiple locations within the same timeframe. GEIPAN, France's official UAP investigation unit under CNES (the French space agency), deployed investigators who worked alongside law enforcement to collect physical samples from the affected areas. This methodical approach demonstrated the seriousness with which French authorities treated the unexplained phenomenon. Laboratory analysis provided a definitive explanation: samples submitted to the mycology department at the Faculty of Pharmacy in Toulouse identified the formations as an exceptional proliferation of Myxomycetes of the genus Badhamia. These organisms, commonly known as slime molds, represent a fascinating biological category intermediate between the animal and fungal kingdoms. The case was subsequently classified as 'A' by GEIPAN, indicating a phenomenon with a certain and mundane explanation.

04 Analyst Notes -- AI Processed
This case exemplifies the value of rigorous scientific investigation in resolving apparently anomalous phenomena. The classification 'A' by GEIPAN represents the highest level of certainty in explanation, reserved for cases where the cause has been definitively identified through physical evidence and expert analysis. The involvement of academic specialists from the University of Toulouse's pharmacy faculty provided authoritative identification of the biological agent responsible. What makes this case particularly interesting from a scientific standpoint is the exceptional nature of the Badhamia formation itself. While Myxomycetes naturally occur in the environment, their spontaneous appearance in such large, circular formations across multiple properties simultaneously is genuinely unusual from a mycological perspective. The precise circular geometry, while naturally occurring, demonstrates how biological processes can create patterns that superficially resemble artificial or unexplained phenomena. This case serves as an excellent example of why physical evidence collection and laboratory analysis are essential components of UAP investigation protocols.
05 Theory Comparison
BELIEVER ANALYSIS
Landing Trace Hypothesis
The initial geometric precision, large diameter (up to 10 meters), and synchronized appearance across multiple properties over successive nights could have suggested circular landing traces from craft. The 30cm width of the rings and their sudden overnight appearance fit classical 'landing ring' reports. However, this hypothesis was definitively ruled out by the physical evidence showing biological origin with no signs of thermal effects, radiation, or soil compression typically associated with physical landing traces.
SKEPTIC ANALYSIS
Fungal Ring Formation
Before definitive identification, skeptical investigators would have likely hypothesized common fungal 'fairy rings' caused by mycelial growth patterns. Many mushroom species create circular formations as they expand radially from a central food source. The black coloration could suggest various dark-spored fungi or decomposition processes. This theory, while in the right biological category, would have been refined by the specific identification of Myxomycetes rather than true fungi.
06 Verdict
ANALYST VERDICT
This case is definitively explained as a natural biological phenomenon caused by an exceptional formation of slime molds (Myxomycetes, genus Badhamia). The scientific evidence is conclusive, based on physical samples and expert mycological analysis. While the initial appearance was certainly unusual and understandably concerning to witnesses, the thorough investigation demonstrates that even highly geometric, large-scale formations can have entirely terrestrial and biological origins. The case's significance lies not in any unexplained mystery, but rather in demonstrating the effectiveness of systematic investigation protocols and the importance of involving relevant scientific expertise. It also highlights how rare natural phenomena can initially appear anomalous when encountered without context.
