Very rare. Generally in polished section, but rarely as free-standing crystals (?).

Paragenetic and General Notes
Microscopic inclusions of molybdenite in germanite are responsible for the c. 0.03% Mo detected in germanite ore by Kriesel (1924; cited in Bartelke, 1976).
Bartelke also records a specimen with a 5 mm crystal of molybdenite associated with stottite and schneiderhöhnite. Pinch and Wilson (1977) indicate that a specimen with a 30 mm hexagonal, pyramidal crystal, with stottite and schneiderhöhnite is known, but this seems questionable and may be a misinterpretation of Bartelke's observation.
Geier and Ottemann (1971a) noted molybedinite intergrown with tungstenite in crypto-crystalline bands.
Gebhard (1999) states that molybdenite has only been observed in polished section.
