British Clavariae. A. D. Cotton & E. M. Wakefield. 195 



darker when moist, fairly tough; branches 4-6 mm. thick, 

 short, blunt, wrinkled, not attenuated, at length hollow. 

 Stem not distinct. Internal structure in longitudinal section 

 of long cells 10-15 /x wide, with narrower elements on either 

 side; latex-tubes present. Basidia rather large, very distinct, 

 50 X lO/A, contents linely granular;- sterigmata 4. Spores 

 hyaline, smooth, ovate or pip-shaped, pointed at the base, 

 17-23 X 8-io/x (average 19 x 9/a), contents vacuolate. 



Habitat. On branches of Alnus. Rare. 



As pointed out in the notes in these Transactions referred to 

 above, von Hohnel regards C. contorta as a morbid form of 

 C. fistulosa, but this statement has been criticised by Lind. 

 Lind's arguments appear to be confirmed by what is known 

 of British specimens. In the paper quoted he gives a tabular 

 comparison of the differences between C. contorta and C. fistulosa, 

 stating that he knows both species well and finds no inter- 

 mediate forms. The chief points of distinction in C. contorta, 

 besides its dwarf, fasciculate habit, are its paler, more greyish 

 colour, entirely smooth club, covered everywhere with the 

 hymenium, its occurrence on dead branches still remaining 

 on the tree, as well as on fallen ones, preference ior Almis incana, 

 and larger spores.
