slightly tapering upward, rough spotted, pallid, but at 

 the base without and within a bright chrome yellow. 

 This yellow foot is a peculiar and constant feature, by 

 which the species may be easily recognized. Boletus 

 cyanescens : a curious form is now and again found as 

 an isolated specimen on the island or about St. Andrews. 

 It is recorded as a sparse grower in the United States. 

 Its cap is rather variable, but usually one of the pale 

 buff, grayish yellow or somewhat brown shades so com- 

 mon among Boleti. The flesh is rigid, white, instantly 

 changing to light blue and then to indigo colour when 

 the cap is broken or bruised. The tubes free, white or 

 yellowish, round and changing color like the flesh. It 

 does not look tempting, but is said to be edible and ex- 

 cellent. Passing on to the family Hydnaceae, we find 

 the genus Hydnum represented by three not at all rare 

 species, though not observed to be abundant in our lo- 

 cality. Of Helvellaceas, we find sparingly Helvetia lacu- 

 nosa Afzel, and Leotia lubrica Persoon, the latter a 

 small plant not irregular in appearance, rather like Hel- 

 vella, but with a very soft, gelatinous, yellow stem. 

 Gyromitra escutenta Fries of the same family, I found 

 only once on the island at the very end of October after 

 all other fungi had disappeared. It is of remarkable 

 appearance and easily recognized, having a dark, chest- 

 nut red, irregularly lobed cap with brain-like convolu- 

 tions. The margin attached here and there to the stem. 

 When cut through, it was found to be hollow, whitish 

 within, and irregular, with a few distinct ribs. The 

 stem is whitish and slightly scurfy. Mitrulla vitellina 

 Saccardo var irregularis Peck, another of the odd-shaped 

 fungi belonging to this family, is not reported as very 

 common, although in favourable seasons it is fairly abun- 

 dant with us. It has a beautiful yellow colour, and looks 

 charming in the bed of damp moss it loves to grow in. 

 The pileus is clavate, often irregular or compressed, 

 somewhat lobed, obtuse, glabrous, tapering below into 

 the short yellowish or whitish stem. It is usually one
