Coniophora puteana (Fries) Karsten Cellar or Wet-rot fungus
Description:
Fruit-body: variable in size, resupinate, composed of one type of hypha only and with a sterile whitish cream or yellow margin.
Spore-bearing tissue: an irregularly wrinkled or humpy, yellowish surface which then becomes olive-green or bronze-colour.
Spore-print: olivaceous brown.
Spores: olive-brown under the microscope, smooth, ellipsoid, thick-walled and 12-14 × 8-9 µm in size.
Cystidia: absent.
Habitat & Distribution: This fungus causes wet-rot in houses, but may also be found on stumps and fallen trunks in woodland.
General Information: The fungus causes a discolouration of worked timber and induces longitudinal cracking with only a few lateral hair-like cracks unlike timber attacked by the dry-rot fungus (see [p. 154]).
