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



415. H. polycystis, n. s. Pustulis sub epidermide lanatis intus 

 multilocularibus ; sporis maxirnis cum pedicellis septatis clavatis, 

 demum deciduis efFusis oblongo-ellipticis multilocularibus. On 

 dead twigs of birch, Batheaston, C. E. Broome. 



Pustules depressed, elevating the cuticle slightly, beneath 

 which they are densely clothed with white or cinereous fiocci ; 

 perithecia globose ; spores large, supported on septate peduncles, 

 at first taken with the peduncles, clavate, at length deciduous, 

 oblong-elliptic, multilocular, oozing out and forming an irre- 

 gular black mass, clothed till mature with a pellucid gelatinous 

 annulated envelope. 



416. H. macropus, n. s. Peritheciis depressis subcollapsis ; 

 sporis pedicellatis, elongatis cylindricis curvulis sporidiolis 3-6 

 repletis. On dead leaves, probably of some Carex, Spye Park, 

 Wilts, Jan. 1850. 



Perithecia depressed, somewhat collapsed, entirely covered and 

 pouring out their spores by a minute orifice, so as to make little 

 black stains on the leaves. Spores furnished with a long peduncle, 

 cylindrical, but slightly attenuated at either end, many times 

 longer than their diameter, somewhat curved, containing 3-6 

 sporidiola. 



417. H. typhoidearum, Desin. Ann. d. Sc. Nat. June 1849, 

 p. 344; Exs. no. 1891. On leaves of Typha and Sparganium 

 ramosum, Spye Park, Wilts, C. E. Broome, Feb. 1850. 



The spores of this species as of the foregoing, H. uredineacola 

 and some others, are not distinctly septate, but contain a row 

 of sporidiola. In separating Hendersonice from Sph&ropsis, care 

 must be taken not to confound mere oil-globules with sporidiola. 

 Species like the present, in fact, forming M. Desmazieres' second 

 section, will, in all probability, at some future period be consi- 

 dered generically distinct. Our specimens are somewhat larger 

 than M. Desmazieres', but otherwise accord with them. 



418. Sphceropsis cylindrospora, Desm. Ann. d. Sc. Nat. May 

 1849, p. 277. Diplodia Desmazierii, Berk, in Gardiner's El. of 

 Forfars. p. 298. On both surfaces and on the petioles of ivy- 

 leaves, West Water, Forfarshire, Mr. W. Gardiner ; Aberystwyth, 

 J. Ralfs, Esq. 



Remarkable for the linear straight spores exceeding their dia- 

 meter in length 6-7 times. The spots are far smaller than in 

 mature specimens of S. leucostigma. 



419. S. Ralfsii, n. s. Peritheciis sparsis tectis punctiformibus 

 fortiter collapsis; sporis minutissimis oblongis. On ivy-leaves, 

 Aberystwyth, J. Ralfs, Esq., with the foregoing, which was how- 

 ever confined to the petioles. 



Scattered over the upper surface of the leaf, punctiform, black,
