vol. i. p. 98 ; Fr. Syst. Myc. vol. iii. p. 329. On decaying 

 Agarics, King's Cliffe. The manner in which the peridiolum 

 in this most curious production is formed after the two lateral 

 branches unite is very remarkable. The matter contained in 

 them is attracted on either side towards the point of junction ; 

 a partition is then thrown out behind each grumous mass, 

 which gradually becomes more and more distinct from the 

 parent branch ; at length the common commissure becomes 

 obsolete, and finally the central septum which consisted of the 

 two coats of the united branches is absorbed.

122. Myxotrichum deflexum, n. s. On paper which had been 

 wrapped round a piece of decayed hazel wood on which was 

 Arcyria punicea, and on the wood itself, King's Cliffe. This 

 species to the naked eye perfectly resembles Myx. chartarum ; 

 but on examination not only does it want the curved apices 

 to the flocci, but the mode of branching is altogether different. 

 In the one the branches form more or less acute angles with 

 the stem ; in the present species they are mostly opposite, set 

 on at right angles and deflexed. The main threads are gene- 

 rally simple, and if branched not trifid and subcymose. 



Forming little patches consisting of little gray downy balls. 

 From these arise a number of radiating threads furnished with 

 a few opposite deflexed branchlets, which decrease in size from 

 the base upwards, so as to give the appearance of a little 

 grove of larches. The branches have occasionally a few short 

 acute branchlets, which are often alternate. Sporidia collected 

 in patches about the base of the threads, oblong-elliptic.
