Randomized trial identifies Stemonitis sp. as a cause of rot disease in Phallus indusiatus, suggesting new challenges for cultivation.

The aim is to identify the causative agent of a myxomycete disease affecting Phallus indusiatus cultivation in China.
Collected sporangia and confirmed identity through microscopic examination and genomic DNA sequencing.
Conducted inoculation experiments with spore suspension in controlled cultivation conditions.
Applied Koch's postulates to confirm the causal relationship between Stemonitis sp. and disease symptoms.
Disease incidence ranged from 50% to 100% in affected crops.
Control boxes showed no symptoms after 40 days, while spore-inoculated boxes displayed disease symptoms.
Genomic analysis showed a high similarity of the isolated strain with known Stemonitis species.

Zhao et al. (2026) studied this question.
