A very wide range of broadleaved species.
conifers (notably larch and pine).
Found fruiting from structural roots up to the lower crown (more rarely including scaffold limbs). Can proliferate extensively amongst lapsed pollard heads.
Perennial. Grows singularly or in tiers. Tough and woody. Chocolate brown surface – sometimes algal-stained. Ribbed white sometimes (usually younger specimens). Young fruiting bodies begin as white masses. White pore surface. Deep tube layer. Chocolate brown flesh. Brown spore. Upper cuticle consistently 1mm+ in thickness. Can become very large. May grow for many years. Rarely anamorphic or aberrant in morphology.
Ganoderma applanatum (very thin outer crust).
Parasitic and saprobic. Can breach reaction zones. Attributed to a selective white rot . Trees with poor compartmentalisation ability / lacking true heartwood are often quickly hollowedout. Prompts buttress development. Can cause structural failure via windthrow / collapse and stem fracture. Hollowness and stability investigations are very necessary, where significant targets exist. Likely that all UK examples are Ganoderma adspersum – likely not a synonym of G. applanatum.
