CYATHICULA. 271 



hymenium convex, the asci clavate, and the sporidia oblong, 

 sublanceolate, with two or more nuclei. (B. & Br.) 



Cooke — Hdbk., p. 714 — without seeing a specimen, drew 

 up a diagnosis from the characters given by Schumacher and 

 Berkeley and Broome. This description is reproduced with 

 a slight modification in the arrangement of words by 

 Phillips — Brit. Disc, p. 158 — to whom the fungus was 

 unknown. Finally, Saccardo, to whom the fungus was 

 also unknown, gives the substance of all previous writers in 

 his diagnosis in Sacc, Syll., viii. n. 875. 



Unknown to me. 



Helotium tuba. Fries, Summa Veg. Scand., p. 355. 



This beautiful little peziza adheres by a claw at the base 

 to the putrid stems of decayed plants in moist places near 

 rills of water. It is shaped like a trumpet in miniature. 

 The height about half an inch. The colour a bright pale 

 yellow. (Bolton.) 



Peziza tuba, Bolton,, Hist. Fung., iii. t. 106, fig. 1. 



Hymeno8cypha tuba, Phil., Brit. Disc, p. 126. 



Phialea tuba, Sacc, Syll., viii. n. 1076. 



The above is all that is known respecting Bolton's 

 P. tuba, hence it is not likely to be recognised again with 

 certainty. 



Excluded species. 



Helotium buccina, Fries, Summa Veg. Scand., p. 355 ; 

 Phil., Brit. Disc, p. 170 ; Sacc, Syll., viii. n. 911. 



Whatever the species kept up by some Continental 

 writers may be, it is quite certain that the British specimens 

 considered as this species by Berkeley do not belong to the 

 Discomycetes. 



Helotium sclerotioides, Berk., Outl., p. 371 ; Phil., Brit. 

 Disc, p. 171 ; Sacc, Syll., viii. n. 960. 



Examination of the type specimen proves this to be a 

 true sclerotium.
