ascribes the position even of the tertiary cap to its being- 

 carried up. 



Morot observed in Lactarius torminosus that from 

 the centre of a stipeless inverted cap, on the top of the 

 primary one, grew forth a normally-orientated stiped 

 cap. This is an interesting case, for there is here no 

 question of any of the structures being secondarily 

 carried up, as both the secondary and tertiary ones are 

 due to a congenital, median outgrowth (PL II, fig. 8). 



A quite different case is cited by Bouclier in Gano- 

 derma lucida. The cap had been broken off its stipe, 

 when from the apex grew a new normal cap and two 

 smaller, incomplete ones. 



3. ADVENTITIOUS BRANCHING. 



Under this heading may be grouped, although in 

 some instances arbitrarily, owing to lack of compre- 

 hension of the phenomenon, those cases of branching 

 which do not seem decipherable either as forking or 

 proliferation, and this owing chiefly to the peculiar 

 position in which the new branches arise. 



Van Bambeke describes, in Mutinus caninvs, the 

 basipetal formation of three or four apparently adven- 

 titious branches, each repeating, on ever dwindling* 

 scale, the structure of the parent individual. The 

 first and highest of these arose " outside the median 

 plane of the primary fruit, from about the middle of 

 the part comprised between the outer limit of the 

 gelatinous layer of the peridium and the basal end of 

 the fruit." 



The present writer observed in three specimens of 

 Tricholoma sordida the complete formation of a secon- 

 dary individual within the tissues of the primary one, 

 viz. within the upper part of the stipe, which is in 

 that region hollow, this cavity being continuous with 

 it and being caused by the splitting of the tissue of 

 the pileus for a short distance above the gill-tissue. 

 In one case the adventitious individual was quite free
