OF CERTAIN TERMITE NESTS. 225 



nothing else in the description to separate it from that species : 

 the spores of F. Janseana, which is identical with Pluteus 

 Eajap and has " pip-shaped " spores, are also styled sub- 

 globose by the same authors. This probably removes the 

 chief difference between P. Treubianus and the following 

 species. 



Pluteus bogoriensis. P. Henn. et E. Nym. Monsunia I. 

 (1899), p. 19. 



Pileo membranaceo-carnuloso, convexo, centro mammoso, 

 subacuto, luride brunneolo, 3-3^ cm. diam. stipite farcto, 

 tereti, gracili, sequali, levi, glabro, albo, basi radicante elon- 

 gata, attenuata, ca. 10 cm. longo. 2-3 mm. crasso : lamellis 

 adnatis, confertis, tenuibus, angustis, e pallido flavescentibus 

 v. subcarnescentibus ; cystidiis ovoideo-clavatis, ca. 30-36 x 

 18-22; basidiis clavatis, guttulatis, 22-25 x 5-6; sporis 

 ellipsoideis, basi apiculatis, 5-6^ x 4, episporio levi, flavo- 

 carnescente.

Only the thin stalk separates this species from Pluteus 

 Eajap. The thinnest stalk I have seen of the latter was 5 mm. 

 in diam. , the pileus being 6x5 cms. It seems quite probable 

 that Pluteus bogoriensis was only a small specimen of Pluteus 

 Rajap. The stuffed stalk may be neglected as I have had 

 several specimens of Pluteus Rajap in which the upper portion 

 of the stalk was longitudinally split internally and therefore 

 hollow. 



Pluteus termitum, P. Henn. F. Amaz. I. in Hedw. (1904), 

 p. 183. 



Pileo carnuloso, campanulato, vertice umbonato-obtuso. 

 brunneolo, radiatim substriato, albido, 3-4 cm. diam.; stipite 

 fistuloso, tereti, substriato, levi, basi interdum curvulo, 

 incrassato, pallide brunneolo, 4-5 cm. longo, 2-3 mm. 

 crasso ; lamellis libetis, confertis, ventricosis, 3 mm latis, 

 pallidis dein fiavidis ; sporis ellipsoideo-fusoideis, utrinque
