Spore Production of Hericium erinaceus. F. I. McCracken, Plant Pathologist, Southern Hardwoods Laboratory, Stoneville, Mississippi 38776. Phytopathology 60:1639-1641. Accepted for publication 15 June 1970. DOI: 10.1094/Phyto-60-1639.

Phenological data on Hericium erinaceus sporulation in 1968-70 indicates that spore production is highest at about midday and is related to daily increases in temperature and decreases in relative humidity (RH). Sporulation in the laboratory at 85-95% RH increased as the temperature was increased from 0 to 24-27 C and ceased at 31-33 C. At 20 C sporulation was higher at 30% RH than at 90% RH.
