Abstract: 4 tables. [Studies were done on Peltigera membranacea, P. polydactyla, and Loabria pulmonaria using special environmental chambers. "Empirical factors have been derived to relate short term rates of acetylene reduction to long term rates of N2 incorporation." Moist conditions produced factors of 8-10 while dry, summer conditions resulted in factors over 20.]
