Abstract

Hydrogen cyanide caused root damage to Poa pratensis, Festuca rubra, and Agrostis tenuis when the grasses were suspended 7 days above a 28-day-old viable culture Marasmius oreades (Bolt. ) Fr. The amount of HCN produced by this culture (Washington isolate 1) averaged 49 ppm per 24 hours collected in 5 ml of sodium picrate during 7 days . Three other isolates (Washington isolates 2- 3 and California isolate 4) did not release HCN until the cultures were autoclaved. Serial dilutions made from water infusion of sporophores inhibited root elongation in Triticum aestivum, Avena sativa, and Poa pratensis.
