cially below ; that of the stem exhibiting all the colours of the rainbow. 
Spores fusiform, yellow-brown when seen by transmitted light. 
This species appears just intermediate between Fries’s sections Sub- 
tomentosi and Calopodes, and is a more delicate species than any there 
enumerated. The stem does not seem to be truly reticulated, nor the 
mouth of the pores to be red, and the change of colour to be far more 
marked than in any of the former section. 
_ SrRoBILOMYCES, gen. nov. Hymenophorum ab hymenio prorsus 
discretum; tubuli ampli, liberi. Spore globosæ vel lato-ellipticæ, 
asperule. Fungi e carnoso lenti, ut plurimum verrucis plus minus 
floccosis quoad pileum ornati. A Boleto differt Sérobilomyces substantia 
magis lenta, et sporis nequaquam fusiformibus. 
332. S. polypyramis, Hook. fil.; pileo lato expanso toto areolato 
verrucoso umbrino carnoso intus rubido: stipite valido lævi fusco-pur- 
pureo; poris latis adnexis, ore rubidis. Hook. fil., No. 104, cum ic. 
Has. Jillapahar, 7,500 feet. August. Rare. 
Smell strong, ammoniacal, at least in age.  Pileus umber-brown, 
6—7 inches broad, expanded, slightly convex, covered with large pyra- 
midal soft warts, which disappear almost entirely under pressure; 
substance thick, firm, and leathery, of a dull red. Stem 5 inches high, 
14 inch thick, attenuated above, swollen below, nearly smooth. Pores 
large, shorter towards the stem, not free. Spores globose, dark purple- 
brown, granulated. 
Allied to Strobilomyces strobilaceus, but distinguished by its ex- 
panded pileus, smoother stem, and less persistent more numerous 
.warts. The spores differ very much from those of true Boleti, being 
more or less globose, without any tendency to be fusiform. 
333. S. montosus, n. s.; pileo verrucis paucis floccosis pyramidatis 
montoso nigro-fusco, interstitiis amethystinis; stipite eoncolore squa- 
moso; poris subadnatis fuscis, ore luteo. Hook. fiL, No. 121, cum ic. 
. Has. On dead wood, and on the ground. Jillapahar, Darjeeling, 
11,500 feet. September. | 
-~ Inodorous, dry, leathery.  Pileus convex, 3 inches broad, rough 
with large pyramidal flocculent brown warts ; their interstices amethyst- 
coloured. Stem 3-4 inches high, 1-1 inch or more thick, curved, 
dark brown, scaly; substance brownish. Veil thick, coriaceous, at- 
tached to the margin of the pileus. Pores brown within, yellow ex- 
ternally, rounded behind. Spores broadly elliptic, brown, rough.
