 ad subplanus, irregularis, subviscidus, scarlatinus, 

 coccineus aut aurantiaco-scarlatinus. Tubi adnati, 

 5-7 mm., flavido-albidi. Stipes 3 ad 3'75 cm. altus, 

 interdum ad 7*5 cm. altus, subtenuis aut crassus (1*2-1*9 

 cm. latus), colore flavo, flavo-pallido aut aurantiaco- 

 scarlatino tinctus. Sporae ellipticae, 5*5-8'5 x 3'4-4*2 /a,

This species resembles Boletus BaUouii, Peck (N. York 

 State Mus., Mus. Bull. 157, 1911, p. 22, pi. viii., figs. 1-5), 

 but the colour is much more brilliant than in his illustrations. 

 The general description and spore shape and spore measure- 

 ments show that the species are closely allied. The species 

 may perhaps also be related to B. sanguineus, With. (Masse: 

 Brit. Fung. Flora, i., p. 266), though there is no change in 

 colour in the flesh when cut. (PI. xxvii., figs. 5 and 6).
