uf April 22, 1943, Dr. G. We. Deadle Stanford University Californta Dear Doctor Beadle: Scme weeks ago I wrote to Dr, BE. V. Abbott of the Bureau of Plant Industry, Sugar Laboratory, Houma, Louisiana, askzing him to try and find Neurospora crassa for you, He sent me some sof]. that had been previously steamed and which at that time showed a pink mold, which he thought might be a Neurospora, I put some of the dirt in tudes and found that within a few days a Neurospora developed. TI had no trouble in getting pure cultures, which are now Dearing perithecia. ‘They are only nine days old so that the spores are not quite ripe, but I am Jucging from their shape and size that they are Neurospora crassa, The cultures look like MN, crassa. I am sending you, under separate cover, a tube which ought to De bearing spores by the time it reaches you, Tf you should find this material of any use, and you wish to make acknowledgment, please refer to Dr, Abdott as donating the culture, ~ = That man Ryan, who came to Columbia from your luboratory, is certainly a bright young man, Ue reviewed Zickler's paper on Bombardia lunata, published in Planta some years ago, Lindegren has never gotten up courage to give it a critical examination, I have a few students meeting once a wesk reviewing some of the work on reproduction and genetics of the fungi, — ; I have very little time to work on Neurospora, but we are maling progress with Neurospora tetrasperma and heterocaryotic visor. You know Lindegren once published a statement that in nature we would not expect to find a Neurospora fruiting. This sample I am sending you is just one of many Instances that prove that he was mistaken, . You ought to be able to get fresh cultures of UN. crassa from almost any one of the mycologists or plant pathologists Wao work in the vicinity of sugar cane fields, This ‘ts certainly a southern species, Best regards, Yours sincerely, Beiap SorantOng “Any (Car B, ©, Dodge Pathologist n ae OCP 5
