New Hosts of Anguillulina dipsaci (Kühn, 1858) Gerv. & v. Ben. 1859, with some notes and observations on the Biology of the Parasite

Abstract

About the middle of June, 1931, the writer received from the Ministry of Agriculture Plant Pathological Laboratory some diseased specimens of carrots which had been growing at Chatteris, Cambridgeshire, where they had been obtained by Mr. Thomas of the School of Agriculture, Cambridge. Microscopic examination showed that they were attacked by Anguillulina dipsaci, and since this is the only record of the parasite on this host or, in fact, on any member of the natural order, Umbellifer it has been thought advisable to give an account of the chief symptoms of the disease shown by the plants.
