LETTER No. 24. 



PLANTS PROM MR. KOMELL. 



I count among my best friends in Europe, Lars Romell of Stockholm. 

 During the three seasons I have collected in Sweden, rarely a week passed 

 that we did not spend a day together in the woods. Mr. Romell has studied 

 the fungi of Sweden for twenty odd years, and I think he knows the Friesian 

 species as no other man knows them to-day. I have learned more from Mr. 

 Romell than from my own work. For three months the past season I collected 

 at Upsala. At the end of the season I spent three days with Mr. Romell in 

 his herbarium, and he kindly gave me specimens of everything he had that I 

 had not collected in abundance. His herbarium is especially rich the ac- 

 cumulation of twenty years' collecting, and he has many species that I did 

 not find. The list herewith is mostly the names as given by Mr. Romell, 

 though I have incorporated many remarks of my own, and Mr. Romell must 

 not be held responsible for any of them, if any are wrong. 



Polyporus giganteus. In Northern Sweden this is a rare plant, and this 

 specimen grew on pine. In Southern Sweden it is more frequent on frondose 

 wood. Polyporus albidus. Grew on Abies, and has no red margin, and does 

 not grow on Pinus sylvest. as stipticus should, otherwise it may be stipticus. 

 (Spores fyz x 5) . Fomes salicinus. On Lonicera, in a park, Stockholm. I find no 

 colored setse. Poria corticola. Polyporus lacteus. Rare on Fagus at Femsjo. 

 Polyporus chioneus. Polyporus fumosus. A thin specimen, usually much 

 thicker. Polyporus fulvus, Fries' Icon, (not Hymen. Eur.) teste Romell. 

 For me it is the late season's growth of Polyporus corruscans. It grows on 

 oak, is rather rare in Sweden, and gets harder and longer pores as the season 

 advances. Mr. Romell and I found at Dalby (Fries' favorite collecting 

 grounds) the same plant on oak, soft and w r ith short pores. This young plant 

 appears to me to be exactly Polyporus corruscans, as described by Fries. 

 Spores 6x8 mic., colored, smooth. The plant is very close to hispidus, where 

 Fries placed it. Polyporus floriformis (or stipticus). On pine, rare.="Poly- 

 porus floriformis, Quel. in Bres. Fung. Trident., desc. not icon, of Pol. trabeus 

 in Rostk. It seems to me different from this species, but I do not know 

 trabeus." Bres. Polyporus leporinus. Agrees with a specimen from Fries 

 at Kew, teste Romell. (It is Polyporus triqueter, in the sense of Bresadola 

 and Polyporus dualis of Peck.) It is not a rare plant on Abies stumps, near 

 Stockholm. Polyporus fragilis, on Abies. Polyporus mollis, on Pinus sylv. 

 It seems difficult to find any marked difference between mollis and fragilis. 

 Poria vulgaris var. calceus, on pine. AVhen fresh the plant is white or 

 pale yellow. Pores small, in strata which would indicate to me that it is 

 perennial, but Mr. Romell claims not necessarily so. Poria (sp.) Poria 

 mollusca, in the sense of Bres. Fung. Kmet. To me it is not in the sense of 

 Fries. Spores subglobose 3-3}^ mic. Trametes micans, in the sense of Bresa- 

 dola (not Fries, I think) albo-carneo-gilvus, Romell. On Quercus ! Poria 

 ferrugineo-fusca, in the sense of Karsten=unita of Fries. This is a rare 

 plant in Sweden, found by Mr. Romell but once, but then abundantly. 

 Spores unknown Poria lenis, in the sense of Karsten. Polyporus triqueter, 

 close to leporinus, except it is a thick plant and leporinus is a thin plant 

 Polyporus cuticularis, on beech in the South of Sweden.-Poria mol-
