What Could Be Wrong With A New House. Meruliporia Incrassata Commonly Known As "Poria"

A Beautifulll Home In An Upscale Neighborhood Only 6 Years Old, Should be An Easy Inspection. And Some Home Inspectors Would Have Given This Home A Clean Bill Health, And Ruined Your Life. (This Home Was Inspected By Steven Abbott In 2012 )

But The Front Door Is Out Of Adjustment And The Trim Is Cracked At The Joints,This Should Make A Good Inspector Suspicious


So I head To That Corner Of The Crawl Space To See What Is Going On. At First Glance Nothing Appears wrong and Inspectors Are Not Required To Remove Insulation 


 So I Start To Remove Some Insulation So I Can See The Framing Members


And What I Find Is Major Fungus Rot Damage To The Structure. So This Deal Is Dead And The Buyer Walk. I Advise The Seller To Retain A Contractor To Determin The Extent Of The Damage.


The Extent Of The Damage Is Massive and Runs In To The Tens Of Thousands Of Dollars. The damage Involves The Entry Floor Structure, The Master Bathroom Floor Structure and The Wall Structure.


 The Fungus Has Comprimised The Structural Integrity Of The Home


All Home Inspectors Are Not The Same, All Home Inspections Are Not The Same. A Bad Inspector Can Ruin Your Life, Cause you Untold Expences and Years In Court.

Meruliporia incrassata commonly known as "Poria" 

"The House Eating Fungus" 

In  the last 2  decades Meruliporia incrassata, an orange colored mushroom shaped macro 

fungus, with the  appearance  of pancake batter, has shown up recently in homes from San 

Diego  to northern California. However, poria incrassata,  the  water-conducting fungus 

occurs mainly in the southern states, it can be found anywhere.  In the past, reports of poria 

were confined mainly to the Gulf states Mississippi, Alabama, Texas, etc. 

"It's a rare fungus, but it's  as common here as anywhere in the world," said UC Riverside 

plant pathology professor  John  Menge. "It's also  the  most devastating wood-decaying 

fungus of houses that we know of'. 

Poria is one of many wood decay fungi that feeds on dead wood. It sounds like science 

fiction  and  looks like it  too,  but poria, like  all  decay fungi,  is  an  organism that needs 

moisture to break  down  and utilize wood  as  a food source, according to forest product 

experts at UC Berkeley. But unlike other wood-decaying fungi, which tend to destroy only 

a six inch area around a plumbing leak or wet window sill, poria has the capacity to begin in 

wet soil as opposed to just damp soil. 

Experts say this water-conducting fungi differs from most other wood decay fungi in several 

respects: Large, semi-tough water-conducting roots called rhizomorphs  are formed which 

transport water by  capillary action from a constant source (usually damp or wet soil) to dry 

wood  in a building, wetting  it sufficiently to support decay.  As decay proceeds, water is 

conducted to dry wood adjacent to that already colonized fungi.  In this manner, as long as 

the supply of water is available, water-conducting fungi can colonize and decay the wood to 

the entire structure. "In other words, because fungus does not have teeth to help it eat, it has 

to spit on the wood. And the  enzyme  it secretes turns the wood to mush.  Any  piece of 

wood exposed to this fungus is destroyed" says poria expert Glenn Sigmon. 

We  used  to think poria would usually start  under  a newly installed patio, with new 

landscaping or with a new room addition, and can travel far from its original water source. 

But that is not always the case. Wayne Wilcox, a UC Berkeley forestry professor, has found 

a similarity among houses with poria and the fact that major landscaping was done within 2 

years  of  poria's onset. He speculates that  the  soil dumped on these suburban lawns 

originated in various forests around the world, where poria occurs naturally and helps in the 

process of decomposition, and he feels poria may have come along for the ride. 

Donna Kingwell, a spokeswoman for the California State's Structural Pest Control Board, 

said "the agency is keenly aware of the potent problems of poria, especially in the southern 

part of California".
