LETTER No. 13. 



Paris, September, 1906. 



List of specimens received at Paris since the last report (June, 1906). My 

 thanks are extended to all who have kindly sent specimens. As these 

 plants reach me from the most remote and distant countries, it is gratifying 

 to find that they are largely the same species and that the number of 

 species is relatively few. I have made no actual count of the number of 

 "puff balls" that I recognize as being good species, but as a guess I 

 should say that three or four hundred, perhaps less, will cover them all. 

 Many times that number have been proposed, but I think many were based 

 on the inexperience of the authors or on slight differences that can not 

 be maintained. The principal question now is the geography of the 

 subject and the distribution of the species. We are gradually learning 

 more in this regard and every specimen received adds to the knowledge. 

 We hope those who receive our publications will continue to send such 

 specimens) as they note. No matter how common they may be, they aid 

 in the work, and are all preserved in our museum. 



ACLOQUE, A., France: 

 Calvatia caelata. 



BAKER, R. T., Australia: 



Polysaccum album. (I have questioned the validity of this "species," 

 but from Mr. Baker's specimens I think it is good as far as species of this 

 genusl go. They are all dubious.) 



BOTANICAL GARDEN, Peradeniya, Ceylon: 



Geaster saccatus, Geaster subiculosum (which is only a large form 

 of G. mirabilis), Geaster triplex. The latter is a form, new to me, with a 

 somewhat scaly exoperidium. 



BRACE, L. J. K., Bahamas: 



Cyathus intermedius, Geaster velutinus (not typical, but tending 

 toward saccatus), Simblum sphaerocephalum, Thelephora (Sp.). 



BRIQUET, J., Dir. Jardin Bot., Geneva (Ex. Herb. Fayod.) : 



Favolus Europaeus, Fomes conchatus, Polyporus caesius, Polyporus 

 fulvo-hirtus, Polyporus hirsutus, Polyporus lutescens, Polyporus placenta, 

 Poria medulla-panis, Trametes abietina, Trametes odorata. (Specimens are 

 listed as named in Herbarium Fayod.) 



BROWN, ROBERT, New Zealand: 



Clathrus cibarius, Lycoperdon gemmatum (a nice lot), Scleroderma 

 verrucosum (I think, though mouldy and am not sure), Sphaerobolus 

 epigaeus (if it is different from Sphaerobolus stellatus).
