EXPLANATION OF PLATES XXXIX— XLIV. 

 PLATE XXXIX. 



FIG. 



Frontispiece. Largest specimen of Fames rimosus, Berk., seen by the author. 

 It is from EJaeodeniJroricroceum (Saffron wood), and measured 73 x 36 x 28 cms. 

 and weighed 24^ lb. 



PLATE XL. 



1. Sporophore of the fungus on Ptaeroxylon utile (Sneezewood). 



2. Same as 1. Note the cracks where the sporophore originates. 



3. Diseased stem of Ptaeroxylon utile cat through and showing the destruction 



caused by the fungus. 



4. Stem cut through longitudinally. Note the brown fungous mass and also some 



empty pockets. 



PLATE XLI. 



5. Pelted mass of mycelium from hollow trunk of Ptaeroxylon utile. 



6. Brown fungous mass, practically in centre of stem, and white wood elements which 



have become delignified and now consist of practically pure cellulose. 



7. ( X 300). — T.S. throiigh diseased stem. Mycelium in large vessels. 



PLATE XLII. 



8. ( X 400). — Diseased stem in longitudinal section. Mycelium of the fungus in 



wood elements. 



9. ( X 400). — Kadial longitudinal section. Mycelium in medullary rays. 



10. ( X 300). — Mass of mycelial threads of the fungus in the wood. 



PLATE XLIII. 



11. ( X 1000).— Mycelium boring its way through the cells of the meduUary rays. 



12. (x 1000).— Mycelium passing through pits of large vessels (a); boring its way 



through wood cells (b) and also some mycelial threads [c). The mycelium 

 frequently runs in close contact to the walls of the cells of the host, and 

 where a wall is to be bored through is usually swollen. 



PLATE XLIV. 



13. ( X 1000). — Mycelium boring through wood cells. 



14. ( X 1000).— Spores of the fungus. They are yellowish-brown, smooth, and vary 



from circular to oval.
