This Nocardia is the cause of some cases of human and bovine 

 actinomycosis, and of the actinomycotic mycetoma. The fungus 

 lives parasitically in most tissues, in which it gives rise to degenera- 

 tive and purulent changes. In the pus sm^all, soft yellow granules- — 

 so-called ' sulphur grains ' — are seen. These sulphur grains consist 

 of masses of mycelium. At the periphery of the granule the threads 

 are radially arranged, and their free extremities become club-like, 

 10 to 20 fji, in length and 8 to 10 ^ in breadth. These peculiar 

 club-like formations have been considered by some authorities to be 

 degeneration forms of the fungus, but Brumpt has demonstrated 

 that they are young active forms, and disappear in old granules. 

 Other writers consider that these club-like formations do not form 

 an intrinsic part of the fungus, but are due to reactive changes in 

 the tissues.
