The dye seems to wash out of tlie hyplue (? by rain), and tinges 

 the surrounding cuticle with a broad patch of pinkish-red colour.

This very beautiful species was found again during a foray in 

 October, 1921, in Clows Wood, Earls wood, by Miss Stansiield. The 

 description given (/. c.) was seen to be very accurate ; there were 

 several specimens, occurring on burnt ground, which would probably 

 ])e similar in certain resi)ects to the garden ground on which the 

 Warwick specimens were found.

 300-380 X 17-20 /x ; spores ovoid, colourless, smooth, then gramdar 

 when mature, usually with two large oil-guttules, 23-25 x ] 4-15 /x ;

Several specimens on the ground under a beech tree, among dead 

 leaves, Kew Gardens. Aug. 1920. 



I gathered tliis in company with Prof, liuller. Together Ave 

 took it back to the Herbarium, and with the help of Miss WakeHeld 

 ascertained its name. Afterwards Prof. BuUer showed us, and 

 several other })ersons, how the sound caused by the "putting" of the 

 spores could easily be heard by holding the cup to the ear. The 

 sound on each occasion lasted for several seconds, and resembled that 

 made by the escape of a steam-jet from a minute oritice ; at tlie same 

 time the spray of the numerous spores against the ear could be felt, 

 and they could afterwai-ds be scra})ed oft' and microsco])ically examined. 

 The same result has since been obtained from many others of the 

 larger Discomycetes, including.ii?///2/;?<7.
