Tony Croft aka hamadryad From my own reading into both Schwarzes work and my own field studies regarding the soft rot capacity it is generally a brown rot, consuming Cellulose/Hemi cellulose, whilst having a soft rot capacity. If we think of the micro environment of wood as a maze, and that fungi use enzymes as keys, the more keys a fungi has the better it may open doors. Different parts of the wood need different enzymes for breaking the locks, the middle lamella for example contain the pectins (a super adhesive) and make the bonds strong between cells/vessels. if a fungi has the enzyme "pectinase" it may use this to breakdown the pectin in the middle lammelae and use the cavity to move around, this would also cause a separation or micro cavity between the bonds between vessels/cells. 23-11-12
luke patton isnt this fungus a simutanious rot ir takes out the lignin and celiouse over time but it is interduced to woodland to make red/marbeled oak that sells for more the only problem is if you dont keep a watchfull eye on your crop the fungi will progress to far and the crop will be useless and its only found on the genus Quercus sorry about my spelling 16-11-12
David Humphries David, my understanding (various references) of Fistulina hepatica, is that it attacks both the hemicellulose and cellulose, putting it within the 'brown rot' lignicolous fungi.

I understand the 'sof rot' fungi, break down cellulose & lignin like Kretzschmaria duesta.

David Kaley Schwarze et al (2000) class this as a soft rot, yet other sources still class this as a brown rot. Is anybody able to shed any light on this? 06-05-12
