tlie Conjuror of Chalgrave/' When, afterwards, 

 it was better understood, and tlie spots came to be 

 regarded as true parasitic fungi, it still for a long 

 time continued to bear tbe name, not even yet 

 quite forgotten, of tlie Conjuror of Clialgrave's fern. 



An examination of tlie spores, both collectively 

 in the pustules, and separately under a high power, 

 will not fail to convince any one who has examined 

 only the species we have already alluded to, 

 that this parasite on the anemone (P. Anemones) is 

 a true Fuccinia, and a most interesting one. The 

 two cells of the spores are nearly spherical, and the 

 constriction is deeper and more positive than in 

 any of the preceding. Moreover, the surface of the 

 spore is minutely and beautifully echinulate, or co- 

 vered with erect spines (plate lY. fig. Q&) . Some few 

 other of the species found in Britain have echinulate 

 spores, but those are not common like the present. 

 One word of caution to the amateur in search of 

 the Puccinia on the anemone. It will be fruitless 

 looking for it on the large foliaceous bracts of the 

 flower-stalk, since these may be turned up care- 

 fully, till the back aches with stooping, ere a soli- 

 tary pustule will be found; but the true leaves, 

 proceeding from the rhizomes, are certain soon to 

 afford you specimens. 



Everybody knows the dandelion, but it is not 

 every one who has noticed the fungi found upon its 

 leaves. These are most commonly of two kinds, 

 or probably the unilocular and bilocular forms of
