Harper: The Clavaria fistulosa Group 57 



In localities where the plants were not abundant, smaller forms 

 like those in D were found with the others. They were some- 

 times attached to balsam needles. They appeared to be the same 

 species, however. They resemble species of Typhula, but there 

 is no sclerotoid tuber at the base. 



Clavaria juncea is quite distinct from other members of the 

 group, but it has the same essential features ; hollow, thin-walled 

 clubs composed of straight, parallel hyphae 6-8 fi in diameter, 

 with many cross partitions. The plants are tough and elastic and 

 it is difficult to keep them from curling long enough to make a 

 photograph. They remain fresh but a short time and when dry 

 are not easy to find. 



The forms or species in this group are well characterized and 

 quite distinct from other club- fungi. The external resemblance 

 is perhaps nearest to some species of Typhula or species of 

 Clavaria with caespitose clubs. 



The real phylogenetic connection of the members of the group 

 with each other is unknown and the superficial resemblances may 

 be misleading. All the forms should be described, but kept to- 

 gether in a single group.
