STROBILOMYCES. 257 



minute coloured warts, situated at a little distance from each 

 other, the intervening spaces being filled up with a fibrous 

 juicy mass, which gradually disappears as the tubes become 

 developed. Some of the warts are conical, others furnished 

 with a spreading radiated border of short filaments, which 

 close the orifice and act as a veil to the infant tubes ; the 

 conical tubes ai'e probably merely unexpanded. In this 

 commencement of the tubes they are very short, scarcely 

 more than a line in length, and barely possess a cavity. As 

 they become more developed they elongate, approximate by 

 the simple enlargement of their diameter, and gradually 

 acquire an open orifice by the disappearance of the fimbriated 

 veil. When at their full growth they are in complete 

 contact, 2-4 lines in length, of a white colour, sometimes 

 tinted with pink or even green, and quite open at the 

 extremity, which is now only a little ragged. (Grev.) 



STROBILOMYCES. Berk. 



Tubes equal, ample, not easily separating from the hy- 

 menophore ; pileus fleshy, becoming tough, covered with 

 large, imbricating scales ; spores large, coloured, epispore 

 rough. 



Strobilomyces, Berk., Outl., p. 236; Stev., Brit. Fung., 

 p. 182. 



Most closely allied to Boletus, distinguished more especially 

 by the pileus being covered with large scales, the flesh of 

 the pileus becoming tough, and the large warted spores. 



Strobilomyces strobilaceus. Berk. (fig. 7, p. 184.) 

 Pileus fleshy and pulvinate, 2-5 in. across, densely covered 

 with large, imbricated, umber-brown floccose scales, margin 

 with irregular fragments of the white veil; tubes white, 

 deep, large, irregularly angular, adnate, but rather shorter 

 round the stem ; spores broadly elliptical, brown, 12-13 x 

 9 ft ; epispore minutely warted ; stem 3-6 in. long, ^ | in. 

 thick below, solid, subequal, coarsely fibrillose, brown below, 

 white and sulcate above.
