Brown and white rot of processed wood

[Fungus]

1. Its exceptionally rare to find such fresh sporophores of Coniophora in buildings.

2. there is visual difference in the morphology and colour of the spores of C. arida, C. puteana and C. olivacea.

3. Asterostroma spp, but not so sure when I look back

 

Pete & Tony,

1. When I do find them in buildings, it's almost always at a side or the lower side of beams in wet cellars.

2. Correct : shape, size and colour of the spores and the presence or absence of incrustrated cystidia, but for building restoration it's only necessary to be sure about it being a Coniophora species to be able to determine the type of wood rot.

Microscopical identification of the exact Coniophora species is only relevant for those "fanatics", who want to publish photo's of species and/or document a species with a dried specimen in their herbarium.

3. I think it could well be an Asterostroma species, such as A. laxum or A. ochroleucum. Did you check for pale brown multiple pointed asterosetae ?

so I have to bin every photo I own, and start over when i have bought my microscopes?

1.Me too, but almost always associated with masonry or plaster.

2. Ah yes, I thought so, and off course you are correct Gerrit; the ID is more often than not entirely 'academic' (OK 'fanatical')

However, it is occasionally mis-identified by building surveyors etc. as S.Lacrymans, so I earn my wages on those occasions!

3. I think A ochroleucum most likely. I didnt take a sample for micro. Pity, as the shape of the mycelium is exceptionally beautiful

Tony..check this one out microscopically if you get a sample

i think mycelium is stunning full stop, and cant wait to document the many species i find especialy the zone of interaction of two species this subject is such a turn on for me, the interactions between species.

 

i am dying to see fistulina hepatica and laetiporus sulphureus do battle in a petri dish!

 

Theres a lab geek in me somewhere!

Yes, fascinating stuff. Check out what Trichoderma spp. does to S lacrymans.
