Memnoniella echinata in West Virginia homes
Stachybotrys' close relative on the same wet cellulose
What this species signals about a 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.
Where West Virginia buildings feed it
Humid continental mountain climate. Hillside construction concentrates water at uphill foundation walls; drainage correction anchors many fixes.
Read those two paragraphs together and the assessment map draws itself: this organism grows where its moisture requirement is met, and West Virginia's climate and housing stock determine where that requirement gets met most often. That intersection — not a generic national checklist — is where instruments should go first.
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.
- Hillside drainage against foundations
- Damp basements
- High rainfall
West Virginia questions
Where does Memnoniella echinata typically show up in West Virginia homes?
The organism's requirements don't change by state — it grows where its moisture threshold is met. What changes is where West Virginia buildings meet that threshold: hillside drainage against foundations Combined with the local housing stock (hillside construction concentrates water at uphill foundation walls; drainage correction anchors many fixes), that's where an assessment should look first.
Does finding Memnoniella echinata mean something different in WV?
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. In West Virginia, weigh that signal against the state's dominant moisture drivers — the species tells you about the water, and the local climate tells you where that water most likely came from.
Who handles Memnoniella echinata contamination in West Virginia?
Remediation requirements are set by the contamination, not the species name: identical playbook to stachybotrys: containment, removal of affected cellulose materials, correction of the long-running moisture source, fine-particle cleaning, and independent verification. We match West Virginia households with providers vetted on containment discipline, fine-particle competence, and independent verification — matching is free for households.
