Another phosphorescent mushroom.- Among a few hundred species 

 of fleshy fungi which I collected in Watauga county, N. C, in the vicinity 

 of Blowing Kock, during the month of August, 1888, was a very common 

 species which was markedly phosphorescent. The species was referred 

 to Prof. A. P. Morgan; who determined it as Agaricus (Clihn/be) iUudem 

 Schw. I had placed a large cluster at the base of a tree in front of the 

 hotel. At night some of the guests noticed the phosphorescent light, and 

 amused then elves by breaking the mushroom into bits and delineating, 

 in the dark, mammoth, hideous figures. The phosphorescence resides in 

 the hymeniuin, and probably in a portion of the hymenophore directly 

 adjacent. Very young plants were phosphorescent, though not so bright 

 as mature ones. I made several teste, but could iind no phosphorescence 

 in the stipe or in the fleshy part of the pilus. After collecting the plant, 

 the phosphorescence continued as long as the hymenium was moist

EDITORIAL. 



The demand for illustrations to accompany the articles sent to the 

 Gazette for publication is steadily increasing as the papers sent increase 

 in importance and permanent value. Illustrations are particularly de- 

 sirable in anatomical articles and those describing new species. We 

 would be glad to illustrate all papers with lithographic plates, but the 

 cost of these in this country is so great that this is impossible unless 

 some kind friend wishes to endow this department of the Ga tte. 

 (There are worse uses to which money could be put.) For financial rea- 

 sons, therefore, it is necessary that we confine the majority of our illus- 

 trations to the photo-engraved plate. As there is considerable labor in- 

 volved in the preparation of drawings which are sent to us for the en- 

 graver, we beg to offer a few suggestions to authors regarding the matter. 

 By attending to these hints their labor will not be increased, our own 



will be sensibly diminished and the final result will be more satisfac- 

 tory. 



Select for your drawing paper the heaviest and best quality of linen 

 paper, such as is used by the manufacturers of blank books for bank 



ledgers. This gives the best satisfaction, for, in case erasures have to be 

 made, this will stand scratching and rubbing without allowing the ink to 

 spread. Next to this is the best bristol board. I ually the two sides of 

 this are different, and care should be taken to use the right side. If it is 

 desired to use much shading, the special stipple papers supplied by photo- 

 engravers should be used with black crayon. 



Make all line drawings twice the size that it is desired for them to 

 Appear. Drawings on the special stipple paper should b one-half larger
