LETTER No. 4 0. 



List of specimens received since last report. My best thanks are 

 extended to those who continue to send me specimens. 



New Species. While I think there are very few "new species" in 

 Europe or the United States, they are constantly being received by me from 

 foreign countries. I do not claim to be able to recognize them, however, 

 excepting in the Gastromycetes and in those sections of Polyporaceae with 

 which I have been working for the past six or eight years with a view to 

 learning the old species. As I do not make a practice of naming and 

 "discovering" new species excepting when working on a monograph or 

 other systematic work, I much prefer that my correspondents who send 

 in new species should name and describe them themselves. In these Letters 

 I indicate the unnamed species that reach me, and if the senders desire 

 to publish them, it is perfectly agreeable to me. I shall not do it unless 

 it comes in connection with systematic work. Isolated descriptions of 

 new species as usually published are very much of a form, and not one 

 out of ten can be recognized from the publication. At the same time 

 we must have names for plants, but I would much prefer that some one 

 else would propose them when I have occasion to use them. 



Please note my recent change of address to England, which is now, 



C. G. LLOYD, 

 c/o Mr. S. A. Skan,

August 5, 1912. Twickenham, England. 



ABBOTT, DR. E. K., Monterey, Cal. Collected in Hall County, Nebraska: 

 Daedalea confragosa. This species has exactly the same hymenium 

 shape as Trametes gibbosa (which is a better Daedalea) of Europe. The 

 texture of Daedalea confragosa is different from Daedalea gibbosa, and 

 the latter species, we think, does not occur in the United States. 

 Catastoma subterranea. 



AMES, F. H., New York: 



Polystictus versicolor. Much more glabrous than usual. Poria sp. 



Fomes rimosus. This species, which is very abundant on locust trees 

 around Cincinnati, is quite rare in the East. Mr. Ames writes me that he 

 examined numbers of locust trees before finding a single specimen, whereas 

 around Cincinnati almost every locust tree is infested with it.
