262 MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRIÆ. 
3. Poron1A.—Stroma between vertical and horizontal, suberoso-fibrous; perithecia collected in edid 
ginate disk. Sporidia black. 
4. Hypocrea.—Stroma horizontal, sessile. The genus is intermediate between Cordyceps and Nectria, 
and differs from Hypoæylon precisely as Cordyceps does from Xylaria*. 
5. HypoxyLon.—Stroma horizontal, sessile, homogeneous, discrete from the matrix, covered at first 
with a floccose furfuraceous veil.  Sporidia opaque. Intermediate between Xylaria and Spheria, 
6. DiatryPe.—Stroma formed (in part at least) from the matrix: perithecia sunk in the stroma; necks 
of the perithecia elongated and often prolonged into a beak. Sporidiat pellucid, simple, not opaque 
or bilocular, as is common in the Hypoxyla. 
7. VaLsa.—Perithecia circinating with long converging necks; ostiola connate or united into a disk. 
8. Nzorria.—Siroma none. Perithecia pallid, free, but often seated on a tuberculate mycelium of a 
variable nature, membranous, flaccid, brightly coloured. Sporidia 8 in an ascus, pellucid (very 
often, I may add, uniseptate). 
9. SPHÆRIA.—Perithecia carbonaceous, black, superficial and bicorticate, or immersed and then of a 
thinner texture; papillate, sometimes beaked. Asci octosporous, mixed with paraphyses, sporidia 
normally septate or cellular, but often simple, ejected like powder.

. B. (CORDYCEPS) Gunn, Berkel. Decades. The asci produce long filamentous sporidia, 
which probably eventually break up into joints, as is the case with other Sphæriæ of 
this division: the sporidia have an alga-like appearance, with an undulating or 
horned outline; the transverse divisions are sometimes very indistinct; each division 
measures about 0-0002 inch. Tag. XLV. fig. 1 represents an ascus X 225 diameters; 
and fig. 2 a somewhat smaller ascus ruptured, with the sporidia protruding, x 450. 
The undulating outline may be caused by the shrinking of the fruit in drying. 
Robin, in his * Végétaux Parasites,’ describes the spores as “courtes, tronquées, 
cylindriques,” 
2. 8. (CORDYCEPS) micrrants, L. ; Fr. S. M. p.323. The asci produce long sporidia, which 
break up into minute joints. Ta». XLV. fig. 3a shows an ascus x 220; and b a 
portion of some of the filaments with the joints into which they divide, more highly 
magnified, _

sporidia, x 325. Sporidia uniseriate, dark reddish brown, irregularly almond-shaped,

and free sporidia, x 225. Sporidia biseriate or uniseriate, clear brown and granular 
at first, eventually quite black, almond-shaped or elliptical, at or before maturity sur- 
rounded by a gelatinous envelope, 0-0015 to 0-0018 inch long.

ue era (C. c)» that Hypocrea is hardly distinguishable from Cordyceps, except by its stroma, but that d 
globose nd m er I may add, that in many species of Hypocrea the sporidia consist of squarish or su
