BOLETUS. 285 



becoming paler towards the margin, flesh very thick, tinged 

 red under the cuticle ; tubes slightly shortened round the 

 stem, but broadly adnate, ^-J in. long, openings subangular, 

 f in. across, whitish, then yellow, finally greenish; stem 

 3-4 in. long, l]-2 in. or more near the base, slightly attenuated 

 upwards, glabrous and even at every stage of growth, white 

 or with a faint buff tinge towards the apex; spores olive, 

 elonga to-fusiform, 15-6 p.. 



In pine woods. The present variety is not uncommon and 

 distinguished from the type by the perfectly even white 

 stem, there being no trace of reticulations at any stage of 

 development.

 not involute, soft, yellowish, changing to blue when cut; 

 tubes ^ in. or more in length, more or less adnate, yellow, 

 when old tinged with green, openings minute, angular, 

 ^-^ mm. across ; stem 2-4 in. long, f-1 in. across at thickest 

 part, usually more or less conical, reticulated, apical portion

In woods, &c. Allied to Boletus subtomentosus and B. 

 chrysenteron, but readily distinguished by the reticulated 

 stem and the smaller openings of the pores. Pileus not 

 involute at the margin, as in B. olivaceus, another ally. 



A very beautiful fungus allied to the present species, but 

 much larger, and presenting some remarkable characters, was 

 found by Mr. W. G. Smith. Pileus 7 in. across, convexo- 

 plane, gibbous, smooth and soft like kid leather, yellowish- 

 brown, becoming cracked into areolae, interstices paler; 

 flesh 1J in. thick, firm, whitish, tinged red under the cuticle, 

 bright blue when cut ; tubes shortened round the stem but 

 not free, \ in. long, yellow, green when bruised, openings 

 roundish, small ; stem 3 in. long, 1 \ in. thick, equal, 

 attenuated at extreme base, colour of pileus below, stained 

 with red above and then distinctly reticulated, sometimes 

 obscurely reticulated below, solid, flesh deep red at the
