albohrnnncns which is a diy and Ihin species recently described 

 in Arkiv för Botanik, Band 11: 3^). 



Polyporus nigrolimitatus. 



This species is described (in Arkiv för Botanik, Band 11: 3 pag. 

 18) as only resupinate. I have to report now, that my friend Egi> 

 LAND bas foiind (at Seljord in Norway) a reflex form wliich appears 

 to belong here. I have been unable to catch any spores, but the 

 habit resembles so closely that of Pol. nujrolimitatiis that I do not 

 doubt of the identity. The resupinate part is about 1 \ -2 cm. broad 

 vertically and 4 ^1-2 cm. horinzontally. The reflex part forms right 

 angle with the resupinate part and is 1 V2 cm. broad. The surface 

 is uneven, brown, ilateritio-badius), minutely tomentose under the 

 lens and not distinctly zonate nor concentrically sulcate. By the 

 last character this species is furthermore separated from Karsten's 

 Fornes tennis. 



Polyporus pannocinctus. 



Since I described this species- I have found it also at the latitude 

 of Stockholm, viz. on the island Vester-Ridö in Mälaren and on an 

 Island in Östersjön, in both places on fallen rotten logs of Fraxinus. 



Polyporus rufopodex nov. nomen. 



Apus, coriaceus, zonatus, scruposo-glaber, albus, basi subtus ru- 

 fescente. Pileus postice attenuatus et gibbus, usque ad 1 cm. 

 crassus, ceterum tenuior (ad medium circa 3 — 4 mm. crassus) non 

 villosus sed dense et subregulariter scrupulosus (quasi granulato- 



^) In a letter my esteemed leader and friend Bresadola has given me the snr- 

 prising information that Pol. albobrumieiis is to him a resupinate form of Pol. fra- 

 gilis, a view which I can neither accept nor understand and which I mention here 

 only to show how the opinions can diverge sometimes in spite of the microsoope. 

 I have about a dozen collections of Pol. fragilis, among which occurs also the 

 resupinate form, and I am unable to identify Pol. albobrunneus with any of these 

 collections either macro- or micro scopically. Among other ditferences Pol. fragilis 

 has daedaloid pores and becomes totally sordid when drying, while Pol. albobrun7ieu8 

 has subregular pores which mostly remain white after drying. At Stockholm I 

 have found Pol. albobrunneus but once, while I collected it repeatedly and abund- 

 antly in Lappland, where I did not see Pol. fragilis.
