Memnoniella echinata
Stachybotrys' close relative on the same wet cellulose
What it tells you about the building
Memnoniella occupies the same ecological niche as Stachybotrys — sustained saturation of cellulose — and the two are frequently found together. Its detection carries the same forensic weight: a long-duration water event in cellulose materials.
Why it matters in assessments
Treated by many practitioners with the same seriousness as Stachybotrys given the shared habitat and related metabolite concerns. In dust results it belongs to the same remediate-and-verify tier.
What remediation requires
Identical playbook to Stachybotrys: containment, removal of affected cellulose materials, correction of the long-running moisture source, fine-particle cleaning, and independent verification.
Dark olive-black growth closely resembling Stachybotrys, distinguished microscopically by spores in chains.
- Soaked drywall paper
- Wet wallpaper and paper products
- Long-duration leak assemblies
- Cellulose insulation after saturation
