10 ARKIV FOR BOTANIK. BAND Il. N:o 3. 
Polyporus. 
Of this genus at least 35 or 36 species were noted, viz. abie- 
tinus, albobrunneus, albolutescens, benzoinus, betulinus, brumalis, 
dichrous, elegans, euporus, ferroaurantius, fomentarius, fumosus, 
hymenocystis, igniarius, lacteus, laevigatus, lapponicus, lenis, 
melanopus, nigrolimitatus, Nuolje, obducens, obliquus, pallescens, 
panno-cinctus, perennis, resinascens, reticulatus, sericeo-mollis, 
stereoides, tenuis, tephroleucus, vaporarius, velutinus, vulgaris, 
zonatus. Two of these (viz. albolutescens and lenis) were not 
collected in Lappland proper, but will probably be found there 
also. 
P. abietinus. 
On Pinus silvestris at Torneträsk station. 
Spores cylindrically oblong, oblique but scarcely allantoid’, 
6—9 x 3—3 !/, —4 v (in specimens from Stockholm). 
Pol. dentiporus PERS. Myc. Eur. p. 104 is a synonym accor- 
ding to the authentic specimen in PERsoon’s herbarium, and 
thus Poria dentipora Bres. Hym. Hung. must be another species. 
P. albobrunneus. n. sp. — Fig. 6. 
Mollusco-lentus, resupinatus, una cum subiculo tenui, albido 
circ. 2—3 mm. crassus, vulgo margine angusto sericeo albo ad- 
presso cinctus, sursum saepe abrupte et crassiuscule marginatus 
vel brevissime reflexus et tum superne una cum toto dorso brun- 
neo-tomentosus. Pori 3—4 vel 2—5 per mm., albi vel passim 
fulvescentes, intus interdum brunnescentes, oris sub lente quasi 
pubescentibus. Sporae allantoideae, sed parum curvatae, 
6x11/, v. Hyphae undulate, non fibulate, 3—4 p crassae, 
aliae molliores, 2—3 t crassae. 
Though I did not collect this species in Torne Lappmark, 
I scarcely doubt that it might grow in the pine region there 
also as I found it quite frequent on rotten trunks of Pinus sil- 
vestris at Nattavara in Lule Lappmark and also at Lakaträsk 
and Jórn. 
KARSTEN'S herbarium contains several collections of this 
plant, all named »squalens». The original Pol. squalens, distri- 
buted in RABENHORST- WINTER, Fungi Eur. No. 3528,is, however, 
another species. 
! That is: sausage-shaped.
