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 maximis 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 flocci ; 
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, Desm. Ann. d. Se. 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. uredineecola 
and some others, are not distinctly septate, but contain a row 
of sporidiola. In separating Hendersonie from Spheropsis, care 
must be taken not to confound mere oil-globules with sporidiola. 
Species like the present, in fact, forming M. Desmaziéres’ second 
section, will, in all probability, at some future period be consi- 
dered generically distinct. Our specimens are somewhat larger 
than M. Desmaziéres’, but otherwise accord with them. 
418. Spheropsis cylindrospora, Desm. Ann. d. Sc. Nat. May 
1849, p. 277. Diplodia Desmazierit, Berk. in Gardiner’s Fl. 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. Perithectis 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,
