K. Stott et A. Broderick, IMPROVED FRUITING OF COPRINUS-ATRAMENTARIUS USING COLD-SHOCK TREATMENT DURING GROWTH, World journal of microbiology & biotechnology, 11(6), 1995, pp. 693-694
Coprinus atramentarius was grown on two commercial composts at a const
ant 20 degrees C or with a cold shock (25 degrees C --> 20 degrees C)
after 10 days. Cold shock was required for it to form fruiting bodies.
