122 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 



Probably extremely common ; but, as it looks like a mere bloom, 

 it may easily escape notice. 



1150. Psilonia discoidea, n. s. Pallide cervina, dein fusca, 

 disco prolifero ; sporis oblongis, margine discreto roseo-alutaceo. i 



On very rotten rails. Langley, Wilts, Jan.-Feb. 1866, C. E. 

 Broome. 



Whole plant 1-2 lines across, variously shaped, orbicular, 

 elongated, flexuous, &c. In the early stage the disk is quite 

 covered by the shaggy coat, which afterwards folds back or 

 cracks, and leaves the stratum of spores naked, precisely as in 

 Myrothecium. Spores oblong or, seen laterally, subcymbiform, 

 •00035 inch long. Our plant, however, wants the gelatinous 

 element of that genus, and is nearer to Psilonia than any pub- 

 lished genus.

1151. Morchella crassipes, Pers. Syn. p. 621. 



On red soil, April 1866, Miss L. E. Lott, at King's Kerswell, 

 near Newton Abbot, Devonshire. 



This magnificent fungus attains a height of 9 inches or more, 

 and is remarkable for its grooved stem. It is of a soft, brittle 

 substance, and does not dry well like the common morel. It is, 

 however, sold in the market at Prague for present use, where it 

 occurs in autumn as well as spring. It is well figured in 

 Krombholz's large work, at plate 16. fig. 1. 



1152. Helvella sulcata, Afzelius in Vet. Ac. Handl. 1783, 

 p. 305. 



On the ground. Bowood, C. E. Broome, Oct. 20, 1863. 

 A small but very neat variety. Spores very broadly elliptic, 

 with a single large globose nucleus, •0006-'0007 long. 



1153. Pe^-i^-a (Helvelloidese) jsA/eiojoAora, n. s. Cupulis po- 

 culiformibus, obliquis, substipitatis, subtiliter pulverulentis, basi 

 venoso-costatis. 



On clay banks. King's Cliffe, M. J. Berkeley. Brislington, 

 C. E. Broome. 



Cup ^-1^ inch across, often rather oblique, yellow or brown- 

 ish, springing from a very short stem-like base, from which 

 branched ribs are given off, ending in little pits. Sporidia 

 •0004 inch long, while those of P. leporina are -0006 with curved 

 paraphyses, and those of P. onotica '0005. Hymenium often 

 venose. Figures are added of the fruit of these species.
