CORRECTION. "There are no regular, stellate lobes (to the exoperidia 

 of Sphaerobolus stellatus) as usually shown in illustrations." Myc. Xotes, 

 p. 432. 



This statement, which was made from observation and photograph of 

 (see Fig. 246) the first fresh specimens I noted of the plant, I have found from 

 subsequent observations to not always be true. I have since seen Sphaerobolus 

 stellatus with the lobes as regular and as sharp as shown in Sowerby's plate, 

 which is the one usually copied. 



The genus Lysurus in the West Indies. There is no record of the genus 

 Lysurus growing in the West Indies, but we have just received from Mr. 

 William H. Patterson, from St. Vincent, a drawing which is undoubtedly a 

 Lysurus. We judge it is the species included in our recent pamphlet as Lysurus 

 australiensis or Lysurus borealis, if there is any difference between these species. 

 The drawing was not accompanied with color" notes, but unless it differs in its 

 color it seems to be very much the same as the Australian and American plants. 

 The occurrence of the genus Lysurus in the West Indies is an interesting 

 addition to our knowledge of the Phalloid subject. 



"I greatly enjoy your breezy, independent way of writing, and pray con- 

 vey to the redoubtable Professor McGinty my appreciation of his researches. 

 I wish he might turn his mind to the Spermatophytes for a great field is open 

 to a man of his talents." Extract from a letter from P. Cal. 



THE GENUS GEASTEROPSIS. 



I have had a great deal of trouble in finding the original publication of 

 this "new genus," but have finally received it through the kindness of Mrs. 

 Flora W. Patterson, who has sent me photographs of the original article. 



The genus Geasteropsis is, in my opinion, exactly the same as the genus 

 Trichaster, described some sixty years ago from Russia, and considered in 

 Mycological Notes, page 189, plate 17. At the time I wrote the article on the 

 genus Trichaster, I considered the genus valid, although I stated the reasons 

 why it was possibly something abnormal. Since writing this article I have been 

 thoroughly convinced that the genus Trichaster has no value, but was based 

 on an abnormal Geaster with deciduous peridia. I have since received undoubted 

 specimens of Geaster hygrometricus, showing exactly this same character. 



THE COLOR OF POLYPORUS OBTUSUS. 



Mr. Perley Spaulding, Forest Pathologist, Department of Agriculture, has 

 written me a few notes regarding this species, which may explain the discrep- 

 ancy in our accounts of its color. 



"If the fungus is wet with rain which has recently fallen, it is almost a 

 pure white; but if there has been a long, dry period, so that the fungus is dry 

 and rigid, the color is apt to be yellow. I believe the difference in statements 

 as to color depend Almost entirely upon whether the fungus is wet or not. I 

 know that all the specimens which we have dried in our collections have a 

 yellowish tint, and as I recollect, all specimens which I have ever found in the 

 field which were dry have had the same yellow tint. I do not remember seeing 

 a wet specimen which had the yellow color." 



POLYSTICTUS PERROTTETIL On my return to Paris, February, 

 1911, I found in the cover what is taken for the "type," labeled "Trametes 

 Perrottetii, Lev. Java. M. Perrottet, 1821." This specimen was not in evidence 

 on my previous visit, and does not bear out my note on page 67 of the Poly- 

 stictrs Synopsis. It was no doubt at that time loaned to Bresadola. However. 

 I still believe that my note is in substance correct, and that this specimen is 

 labeled as coming from "Perrottet, Java" by mistake. It is exactly the same as 

 Polystictus trichcmallus. and the same as the abundant specimens labeled by 

 Levei.lle on a printed label, "Guyane francaise, M. Poiteau." Polystictus tricho- 

 mallus is an abundant plant in "the American tropics, and many specimens are 

 in the museums, all from the American tropics, except this one, which I am 

 sure was labeled through error as coining from Jara. I do not believe the 

 species grows in Java, or any portion of the East.
