Messrs. Berkeley and Broome on British Hypogceous Fungi. 77 



collections which have been distributed by Vittadini, as far as we 

 have been able to ascertain, — has lately occurred abundantly in the 

 neighbourhood of Bristol, and is far more distinct from G. verru- 

 cosa than would be inferred from the name or description. The 

 whole peridium is of a rich brown, and is densely clothed with 

 brown bristles wherever it extends. The sporidia are very much 

 larger and far more coarsely granulated, the granules indeed being 

 often bifid. The single specimen from Bowood formerly referred 

 to this species, is now ascertained, on comparison of authentic 

 specimens, to be the same with G. verrucosa, Vitt., the specimens 

 communicated under that name by Klotzsch and figured in the 

 ' Flora Regni Borussici ' differing materially from the Italian 

 species. The sporidia of G. papillosa often contain two nuclei, 

 but sometimes there is but one *. 



* We take this opportunity of describing two new Pezizce remarkable for 

 their globose, tuberculate or echinulate spores, the first of them being re- 

 markably analogous to Genea verrucosa. 



Peziza (Aleuria, Helv.) radula, Berk, and Broome. Magna cupulaeformis 

 sessilis demum depressa externe verrucis subaequalibus exasperata atra, intus 

 vinoso-fusca ; sporidiis globosis tuberculatis. On the ground in woods near 

 Bristol. 



Cup depressed, sessile, nearly an inch across, black externally, broken 

 into nearly equal distinct subconical warts like those of Genea verrucosa. 

 Hymenium of a dark vinous brown. Asci large, obtuse ; sporidia large, 

 globose, containing a single nucleus rough with obtuse distinct tubercles ; 

 paraphyses septate with the ultimate articulation clavate. 



This species has externally a close resemblance to a crushed specimen of 

 Genea verrucosa or Klotzsckii, and singularly enough, the sporidia are 

 somewhat similar, though differing in size. The hymenium however is 

 naked, not to mention other points. Pez. bufonia, Pers., appears closely 

 to resemble it, but that is described as substipitate and of a bright red- 

 brown, and we have no information as to its sporidia. Messrs. Tulasne 

 have sent a verrucose Peziza which is almost closed, and covered with hairs 

 like Genea papillosa, but with elliptic smooth sporidia. 



P. (Lachnea, Sarc.) trechispora, Berk, and Broome. Depressa, planius- 

 cula aurantio-miniata extus pilis pallido-fulvis vestita; sporidiis globosis 

 echinatis. On the naked ground in woods or on the sloping wet banks of 

 rivulets. King's Cliffe, Bristol, &c. Mons. Leveille has sent the same spe- 

 cies from Montmorency. 



Cup £rd of an inch or more broad, depressed or slightly concave, orange, 

 paler externally and clothed with rather rigid tawny bristles. Asci elon- 

 gated. Sporidia globose, sharply tuberculate. Paraphyses very slender, 

 linear. 



This species is no doubt frequently confounded with Pez. scutellata, which 

 it resembles very closely, though distinguished at once by its very different 

 sporidia, those of the allied species being smooth, much smaller, broadly 

 elliptic with a single nucleus. There is no analysis extant of Pez. umbrosa ; 

 it is therefore impossible without authentic specimens to say how far it re- 

 sembles that species. Pez. scutellata grows we believe invariably on rotten 

 wood. 



Mr. Thwaites has found another species with echinulate sporidia, but be- 

 longing to the same series with P. repanda. P. phhjctospora, Mont., and 

 P. aurantia have also rough sporidia.
