Mycologia 



be found on the leaves in the woods and sometimes they are very 

 abundant. Clavaria fistulosa is more rare. Only once have I seen 

 it abundant at Neebish. I also found a single specimen near 

 Lake Rosseau, in Ontario. 



I show in the plates the following forms belonging to- the 

 group. 



Clavaria ardenia Sow. PL 3 



This form is more abundant than Clavaria fistulosa at Neebish. 

 The clubs are enlarged and inflated at the apex. They are ab- 

 ruptly pointed when young but become truncate and often per- 

 forated when old. The plants are figured by Sowerby in his 

 plate 215. The species is said to grow 8 inches high in the British 

 Isles. Our plants were 4-7 inches high and about one fourth of 

 an inch thick at the apex. Stevenson says it is the only form of 

 Clavaria fistulosa found in the British Isles. His description reads : 

 " Ferruginous, then date-brown, simple, very long, more than 20 

 cm., thickened upward, acute when young, then obtuse or hol- 

 lowed out at the apex, tomentose at the base, not rooting, on 

 fallen branches." The spores are given in the Sylloge as broad, 

 hyaline, ovoid, apiculate at one end, 15 X 8-9 The description 

 fits our plants exactly but the spores were narrower, 12-16 X 5~7/*- 

 The plants grew on the ground in coniferous woods and the clubs 

 were attached to small sticks by copious whitish mycelium as 

 shown in the illustration. The species is usually considered a 

 variety of Clavaria fistulosa.

The photograph was taken from the Lake Rosseau specimen. 

 It is not enlarged or inflated at the apex. It is the form illustrated 

 by Britzelmayr. It appears to be typical Clavaria fistulosa and is 

 described, as follows: "Simple, slender, very long, strict, fistulose, 

 somewhat obtuse, yellow becoming reddish, root short, villous, 

 spores ellipsoid-oblong, commonly obtuse above and attenuate at 

 the base, hyaline, 14-16 X 6-7 /a." It is said to be very closely 

 akin to Clavaria wiacrorrhiza and was considered by Fries to be 

 a large form of Clavaria juncea.
