. Two Species of Fuscoporia 



1. Fuscoporia tenerrima (Berk. & Rav.) comb. nov. 



Polyporus tenerrimus Berk. & Rav. ; Berk. Grevillea i : 65. 1872. 

 Porta tenerrima Cooke, Grevillea 14: 115. 1886. 



Described as below from Ravenel's Carolina collections on the 

 bark of Ulmus americana, and known only from that region and 

 on that particular host. It is rather difficult to decide where it 

 belongs without seeing fresh, well-developed specimens, but its 

 affinities appear to be with Fuscoporia. 



" Entirely resupinate ; very thin and tender, of a watery texture, 

 tawny; pores very small, confluent, with very thin dissepiments. " 



Ellis, N. Am. Fungi 922; Rav. Fungi Am. 710; Rav. Fungi 

 Car. 3 : ?3- 



2. Fuscoporia nebulosa (Berk. & Curt.) comb. nov. 



Polyporus nebulosus Berk. & Curt. Jour. Linn. Soc. 10: 317. 

 1868. 



Poria nebulosa Cooke, Grevillea 14: 115. 1886. 



Described as below from Wright's collections on dead wood in 

 Cuba. Known only from one collection. The entire plant, in- 

 cluding the tubes, is very thin and delicate. It apparently belongs 

 in Fuscoporia, but I have not been able to examine it micro- 

 scopically. 



" Subiculo tenuissimo pulveraceo ferrugineo ; hymenio fusco, 

 poris parvis brevissimis angulatis, dissepimentis tenuibus rigidis 

 integris."

A Double Mushroom 



A peculiar specimen of the ordinary cultivated mushroom, 

 Agaricus cavnpester, was sent me last October from the Hupfel- 

 Carrar Mushroom Plantation in the Bronx, with the following 

 note : 



"We are herewith sending you, under separate cover, a freak 

 of nature in the form of a mushroom picked from our mushroom
