If a section is made through the axis the tissue is found to be 

 entirely derangied, a few spiral vessels only being visible, and on 

 the sides, which are very dark, perforated with a series of globose 

 cavities, the whole of the darker portion being converted into a 

 cellular stroma. Pellucid branched filaments traverse the cavi- 

 ties, and are mixed with and attached to the spores, sometimes 

 in considerable numbers. 



The nearest species to it is doubtless Ustilago Montagnei, from 

 which it differs in its more globose and larger spores. Those 

 of that species are gjoiT^^^ ^^ ^^ mch. in diameter. When the 

 spores of the two are placed together on the field of the micro- 

 scope, there is a marked difference. 



56. Cephaleuros densus, Kze. ; Fr. Syst. Myc. vol. iii. p. 327 ; 

 Salle, no. 77. On coriaceous leaves. 



57. Peziza Doming ensis. n. s. Sessilis ; cupula plana margin e 

 undulato, extus glabra pallida hymenio vinoso-fusco. Salle, no. 42. 

 Apparently on wood, but with mould attached to the base. St. 

 Domingo and St. Thomas. 



Cup 1 inch or more across, sessile or very slightly elon- 

 gated and wrinkled at the base, externally smooth and even, pale 

 salmon-coloured ; margin undulated, at first somewhat incurved ; 

 hymenium of a rich vinous-chocolate. Asci cylindrical, very 

 long, straight ; sporidia elliptic, with two nuclei which are how- 

 ever mostly confluent. 



Resembling somewhat small specimens of Glaoporus con- 

 choides. It is very hard when dry. I cannot point out any 

 closely allied species. Though not oblique, it seems to be nearest 

 to such species as P. onotica, or perhaps to the two pedunculate 

 species which follow. 



The same species is probably presented also by no. 83, of 

 which there is but a single specimen. At first sight it looks like 

 a Merulius, but the veins merely arise from the contraction of the 

 hymenium. This undoubtedly grows on wood. 



58. Peziza hystrix, n. s. Cupula subglobosa cum stipite gra- 

 cili setis longis cellulosis exasperata ; sporidiis ellipticis apicibus 

 apiculatis. Salle, no. 35. On dead wood. 



Cup I of an inch or more broad, subglobose, with the margin 

 strongly inflected when dry, clothed, especially towards the mar- 

 gin, with long stiff bristles, which are composed of numerous 

 linear cells. Stem 1 inch high, scarce a line thick, flexuous, 

 sparingly sprinkled with bristles like the pileus. Hymenium 

 concave. Sporidia elliptic, pointed at either end. Endochrome 

 scarcely bipartite. The colour of the whole when fresh is pro- 

 bably scarlet. 



This species is closely allied to P. sulcipes and P. Hindsii, but 

 distinguished from both by its long bristles. These do not, like
