Pathogen identification reveals stipe rot causing substantial losses in Morchella crops, suggesting bacterial origin.

Chryseobacterium indoltheticum was identified as the pathogen causing stipe rot in Morchella sextelata.
Around 40% of fruiting bodies showed severe symptoms, indicating a significant agricultural threat.
Whole-genome sequencing and phylogenetic analysis confirmed the identity of the bacterium responsible for the disease.
The rot disease suggests a soil-borne pathogen, emphasizing the need for improved agricultural management strategies.

Zhang et al. (2025) studied this question.
