152 ON SOME CEYLON SPECIES OF AGARICUS. 
hexagonal areæ, which are pale and striated at the margin, brown and verrucose in the 
centre, calling to mind the outer coat of some Lycoperdon; stem 3 inches high, 3-1 inch 
thiek at the base, 1-3 thick above. 
This is one of the most curious species in the multitudinous genus 4garicus; it is 
undoubtedly allied to 4. bombycinus, but, unfortunately, we have not been able to find 
any spores on the gills, which are, perhaps, in an imperfect condition. 
9. A. (PHOLIOTA) MICROMERES, Berk. & Br.: cæspitosus; pileis subhemisphæricis depres- 
siusculis glabris, margine annulo crenato appendiculato, lamellis adnatis argillaceis 
acie candidis; stipitibus fistulosis flexuosis glabris. (Thwaites, Ceylon, no. 690.) 
Hab. On dead wood, Peradeniya, July 1868. 
Densely cespitose; pilei yellowish, slightly depressed in the centre, fringed with the 
ring, which separates entirely from the stem, 3-3 inch across; stems paler, 1 inch high, 
scarcely a line thick; spores yellow-brown, :00025 inch long. 
A minute species, apparently allied to Agaricus pudicus. 
10. A. (PsALLIOTA) SPILOCEPHALUS, Berk. & Br.: pileo expanso carnoso umbonato, albido, 
centro squamulisque punetiformibus atro-purpureis, margine striato, carne alba; 
stipite pallido sursum attenuato striato, floccis intricatis araneosis farcto; annulo 
amplo supero; lamellis atro-purpureis liberis. (Thwaites, Ceylon, no. 698.) 
Hab. On the ground, Peradeniya, July and August 1868. 
Pileus 4 inches across; stem 3 inches high, $ thick in the middle, marked with dark 
streaks. 
Allied to 4. campestris. Apparently the same as Gardner's no. 65. Differing from 
all its allies, except 4. silvaticus, in the hollow stem, which, in this case, is curiously 
stuffed with delicate threads. 
Mr. Thwaites, amongst other matters of interest, has sent a very fine drawing (no. 688 
bis) of Lentinus stenophyllus, Berk. Lond. Journ. Bot. 1847, p. 495, tabb. 17, 18. f. 1. It 
appears from the drawing and the accompanying specimens, that the pileus, when first 
developed, is covered with acute warts in the centre, while the margin has a single row 
of large floecose wart-like scales. The upper part of the stem, moreover, is pitted with 
minute black specks.
