Macro photograph of the entomopathogenic "Zombie fungus" (Paraisaria gracilis, syn. Ophiocordyceps gracilis) growing from mossy soil in the alluvial forest of the "Hördter Rheinaue" nature reserve, located between Kuhardt and Hördt, South Palatinate. This specimen features a fertile stroma head (spore carrier) with a diameter of approximately 5 mm. The parasitic species infects lepidopteran caterpillars or beetle larvae underground, mummifying the host's body before the long-stalked fruiting body emerges above the surface to release spores. According to the German Red List Centre, the species is classified as Least concern, but its current population status is noted as very rare.
