LETTER No. 23. 



List of specimens received at Paris from the date of my arrival (July) up 

 to the twelfth day of November, 1908. 



I beg to thank my correspondents in Europe and foreign countries for their 

 liberal sendings. I am now engaged in a study of the polyporoids of Europe, 

 and have been greatly aided by the specimens received. I do not claim to 

 have a critical knowledge of European species ; in fact I am just making a 

 good start. I spent three months this season in the woods of Sweden, and was 

 enabled to satisfy myself as to many of Fries' species, largely aided by the 

 advice and kindness of L. Romell, Stockholm, who has, I think, the best 

 knowledge of any one of the Swedish species. 



As to nomenclature always a troublesome question owing to a variety of 

 views on the subject I have concluded to adopt the names used by Elias 

 Fries for the polyporoids of Europe in most instances where I have no doubt 

 as to Fries' views. I will explain my reasons for arriving at this decision in 

 another letter, simply contenting myself to state here that the great majority 

 of polyporoids are surely and definitely known by Friesian names, and that in 

 my opinion it is not wise to go beyond Fries, and put aside what in most cases 

 is a certainty for an uncertainty. 



The American specimens that were crowded out of Letter No. 20 will be 

 acknowledged in the next Letter devoted to American species. I am advised 

 that a number of packages have been sent to my address at Cincinnati, that 

 will shortly be forwarded to me at Paris.

 December, 1908. 63 rue Button, 



Paris, France. 



ALLEN, W. B., England: 



Lycoperdon (? to me, but a form of nigrescens, I think). 



BADET, REV. L., Italy: 



Clathrus cancellatus (beautiful specimens). 



BECKER, DR. H., South Africa: 



Cyathus vernicosus. (The exterior hairs of the cup are more strongly 

 developed than in the European form, approaching those of C. striatus, but 

 the interior of the cup and the spores are the same as the type. One can not 

 make a [good] new species on a character like this.) Genus, unknown to 

 me Scleroderma Cepa Calvatia, immature. 



BERNARD, DR. CHARLES, Java: 



Lycoperdon Wrightii (Spores are not truly globose, but it has all the 

 essential characters of this species.) Lycoperdon (species unknown to me.) 

 Genus unknown to me, immature Lycoperdon (close to Wrightii) Cyathus 

 Poeppigii (as it develops that this is the most common Cyathus in the tropics, 

 it is unfortunate that Tulasne gave it such an uncouth name).
