P. nigrolimitatus n. sp. — Fig. 3. 
Resupinatus, stratosus, subiculo ferrugineo, fomentario, 
1—3 mm. vel ultra crasso, lineis nigris percurso, ad marginem 
saepe callos vel nodulos crassos submolles steriles, guttas aqueas 
stillantes, dein grosse foveolatos formante. Hymenium e luteo- 
olivaceo pallide umbrinum vel tabacinum, circ. 2—10 mm. 
erassum. Pori minuti (5—6 per mm.), intus in fundo pallido 
sub lente minutissime spinosi. Spinae subulatae, fuscae, 20— 
40x6—9 p. Hyphae hym. 2—3 » latae, Sporae hyalinae, 
subulatae, 4—6 x1/,—2 u. 
On rotten wood of Pinus silvestris at Nattavara and Jörn. 
VLEUGEL has collected the same species at Umeå. In the region 
of Stockholm it is found in several places, for instance Lidingo, 
Bedaró etc. (but only on Abies). 
This is the plant, mentioned as »Ch. tenuis» in my Hym. 
austro-americ. p. 14. It is, however, neither Chaetoporus tenuis 
K. nor Fomes tenuis K. nor Pol. spongiosus PERS. according to 
a specimen in PERSOON's herbarium, nor Pol. spongiosus FRIES 
nor Pol. spongiosus SECR. (»chair blanche»). In my opinion, 
it cannot be Boletus resupinatus Bort. either, as this is found 
growing »on dry, decayed hazel boughs», while my plant is col- 
lected on coniferous trees only. — In Krox & ALMQUIST, Svensk 
Flora, II. p. 266 (1907), it is described under the name Pol. spon- 
giosus on the authority of BERKELEY who has so determined 
a specimen! in the Kew herbarium. 
The name »nigrolimitatus» now suggested alludes to the 
fact that each new stratum of the subiculum is separated from 
the older one by a thin black layer, which appears as a fine 
sharp black line on a vertical section of the fungus. 
P. Nuoljae n. sp. — Fig. 11. 
Resupinatus, albo-pallidus, in statu sicco subochraceus, 
interdum tinctura levissima subrosea, tenuissimus, vix '/, mm. 
crassus, subiculo (fere) nullo, margine nudo vel fere ad instar P. 
reticulati minutissime farinaceo vel araneoso. Pori minuti 
4—7 per mm. Hyphae 3—7 y latae, distinctae, subfragiles, 
! After further examination, Massry will probably find that hymenial 
spines are present also in that specimen.
