Himalayas, and whicli is frequently found covered with dark-brown 

 spots of fungi. The spores are septate, with short peduncles 

 (which are liable to be easily detached), oval in shape, and with a 

 comparatively transparent, nipple-like projection on the upper part, 

 vide Fig. 15. [Puccinia cruciferarum, Cooke.] 



Fig. 16 shows the appearance of the spores of a Puccinia found 

 on the upper and lower surfaces of the leaves of an umbelliferous 

 plant. [Puccinia umhelKferarum, D. C] 



Fig. 17 represents the magnified appearance of bodies which 

 form patches on the under surfaces of the leaves of the oak, species 

 of laurel, wild rose, &c. They resemble the agarics in shape, are 

 hollow, or filled with a pink fluid, which, when pressure of the 

 covering glass is used, exudes through the lower part of the stipe 

 or stalk. [An Erineum, not a fungus, but diseased tissue. — M. C. C.] 



Fig. 11 illustrates two of the sporangia which form the tough, 

 cotton-like fungus met with on the under surface of the briar leaves, 

 or on the petiole. The conceptacles which contain the spores are 

 bi- and tri-partite, and terminate in long filiform appendages. Two 

 of the nearly colourless tuberculated spores are depicted to the 

 right of the sporangia. [I have seen no specimen of this. The 

 figures might belong to Coleosporium jpingue, but the description 

 is rather that of some Erineum. — M. C. C] 



I feel that an apology is necessary for writing on a subject with 

 which I am so little acquainted ; but as I had collected the 

 materials many years ago, I considered it better that they should 

 be made public at once, rather than be lost. Perhaps others more 

 competent may be induced to pursue the subject more fully than I 

 have been able to do, as it is one of great interest, and not without 

 some advantage, and indeed, at all events, the small collection of 

 leaves now before me recalls to my memory many pleasant days 

 spent amidst most beautiful scenery in one of the finest climates of 

 the world.* 



* The technical descriptions of such of the foregoing fungi as are new to 

 science are published in the current number of ' Grevillea.'
