can not understand how Berkeley could do such naming. Hydnum (sp.), Thelephora 

 anthocephala, Polyporus adustus, Thelephora cuticularis, Thelephora vialis (?), 

 smaller pilei than usual, Lentinus cochleatus, Lentinus vulpinus, Pterula multifida, 

 Daedalea confragosa, Cantharellus infundibullformis, Craterellus cornucopbides, 

 Lycogala Epidendrum, Polyporus (sp. unknown to me), Polyporus (sp. unknown to 

 me, cfr. albiceps), Helvella crispa, Polyporus frondosus, young (I think), Sclero- 

 derma Cepa, Boletus sphaerosporus. It is not generally known that we have a 

 true boletus around Minneapolis with globose spores. The only one known in the 

 world, I think. Polyporus radicatus (very ?), much too small, Sebacina (very ?), 

 white, incrusting, with exactly the habits of Sebacina incrustans, but of a soft 

 texture. A section shows a loose tissue of branching hyphae, but I find no 

 lymenium. It is something curious. 



CORRECTIONS. 



In Letter No. 16 we reported a Tremella received from G. D. Smith, Ohio, as 

 Tremella fusiformis, and commented on its resemblance to a Clavaria. We were 

 not satisfied with the determination, however, and sent the plant to Professor 

 Farlow. He kindly advises us that it corresponds to a specimen in the Curtis 

 Herbarium, named by Berkeley "Corticium tremellinum var. reticulatum" (sic.). 

 We are at a loss to understand how it was possible for Berkeley to so name it, 

 as it has no relation to a Corticium, and is not reticulate. However, we would not 

 wish to comment on it further until we see the plant so named in Berkeley's 

 herbarium. 



Some of the specimens sent by G. C. Fisher and reported in Letter No. 16 

 as from Ohio, were collected in Florida (the error being ours), viz.: Lycoperdon 

 cruciatum and those that follow. 



Some of the specimens listed in Letter No. 14 from Miss Rose H. Lane, Cali- 

 fornia, were collected in the Philippines, as' we have since been advised. We 

 noted at the time that they were of a tropical type, previously unknown to the 

 United States.
