lusca, as labeled. Poria luteo-alba, as labeled. Poria inconstans Poly- 

 porus trabeus, teste Bresadola.- Polyporus vulpinus, from Dr. Haglund. 

 Daedalea unicolor, from Lapland. This species from Northern localities is not 

 so thin and pliable as the more Southern species. I have noticed that even in 

 Sweden. Poria spongiosa, the Fome* form, very rare, teste Romell. Mr. Ro- 

 mell gave me also the " Poria" form, which it is difficult to believe is the same 

 species. Poria incarnata, as figured by Fries, teste Mr. Romell. On Abies. 

 Poria (sp.) Porotheiium fimbriatum, on Betula. Stereum abietinum. 

 Stereum pini. Hydnum strigosum, on Populus, in Northern Sweden (Umea.) 

 I would merely remark in passing that the plant from North America, in- 

 cluded in Mr. Banker's paper under this name (juggled), based on a specimen 

 in the herbarium of Schweinitz, has no resemblance to the species, in fact is 

 not a Hydnum. Lenzites heteromorpha. This is one of those polymorphic 

 species that take hexagonal, irpicoid, and lenzitoid forms in the same collection. 

 It grows only on Abies, and was previously unknown to me. It seems to me 

 very close to Polystictus biformis. Polyporus velutinus, form (for Mr. 

 Romell.) Polyporus croceus, on oak Poria sp. Merulius rufus on birch. 

 Solenia ochracea, on frondose wood. Dsedalea unicolor, on Abies. A 

 rare host. Merulius species Solenia confusa (from Otto Jaap, Branden- 

 berg) Lenzites saepiaria, on Prunus ! Cyphella eruceeformis, on poplar. 

 Stereum odoratum, on Abies. Merulius serpens, on Abies. Merulius 

 Corium, not rare in Sweden. Poria connatn, on Acer. Cystidia abun- 

 dant. Merulius crispatus, teste Bresadola, on Salix Caprea. Solenia urceo- 

 lata, on birch. Stereum ochroleucum, from Umea, Northern Sweden. I 

 think it is the same plant we have so common in the United States ;m<l 

 which we call there Stereum versicolor or fasciatum. Lenzites abietina (from 

 Dr. Haglund) Polyporus vulpinus. This is a rare plant in Sweden, and has 

 only been found by Mr. Romell on poplar in recent years. Fries says "fre- 

 quent, Upsala" but I did not find it at Upsala at all. Poria cinerescens, vide 

 Bresadola. (I am inclined to think this is Poria molltisca in the sense of 

 Fries=also the specimen of subfusco-flavida in his herbarium). Purin spon- 

 giosa, teste Bri-sadola. A rare plant in Sweden, and strongly marked by its 

 "spongy" border. On Abies. Polyporus (sp.) on Frnxinus at Sandemar. 

 Polyporus velutinus, from Upsala. Poria squalens from Russia, on 1'iniis 

 sylvestris. Spores 4x 12, cyst, curved. Is it not callosa ? Poria obliqua, on 

 Tilia, collected in May. Fomes vegetus, on oak, near Stockholm. Koines 

 vegetus is supposed to be only a condition of Fomes applanatus, with annual 

 strata between the pore layers, such as is the normal condition of Fomes con- 

 natus. Poria purpurea. on Alnus. Trametes campestri^, teste Patouillard, 

 who tells me it is not a rare plant in France. I can not believe it is the same 

 as Trametes micans, as has been stated. Polystictus versicolor, form, tit 

 Femsjo. Certainly a most marked form. Poria obliqua. This is a peculiar 

 species of Sweden. I do not know whether it grows in the United States or 

 not. What Berkeley so referred from Lea has no resemblance. It begins 

 under the bark of live trees, Betula, Populus, Ulmus, and ends by killing the 

 bark. -Fomes salicinus, on Viburnum. Poria nitida, on Fagus, Femsjo. 

 Poria obliqua, on Ulmus. Poria radula, from England. It is Poria vaporaria, 

 in the sense of the English mycologists; surely not in the sense of Fries. 

 Poria mollusca, teste Bresadola, on frondose wood. Poria pnnctata. on 

 Salix. (Mr. Romell thinks the type specimen is on frondose wood, not
