POLYACTIS INFESTANS, (NOV. SPEC.) 
By Professor F. Hazslinszky. 
Polyactis corynibosa mycelio, in contextu celluloso plantae vivse, 
infra epidermidem, adiloso, filis continuis dicliotoma ramosis spar- 
sim anastomosantibus 0.001-0.002 mm. crassis chloropliyllurn 
absorbentibus. Mycelio superficiali e floccis serpenlibus parum 
crassioribus viridifuscis, contexto. Floccis fertilibus erectis sim- 
plicdbus articulatis ; articulis diametro ter quaterque longioribus, 
oblonga-cylindraceis viridi-fuscis. Inflorescentia corymboso-capi- 
tata, ramis solitariis vel binatis dicliotome ramosis. Sporee acrogene, 
obovatte vel ovales 0.010-0.012 mm. longse, albas, diu persistentis. 
Vegetat parasitice in caulibus mediis Cannabis sativce ad urbem 
Iglo in Hungaria, et exugit caulex adeo ut pars superior marcescat. 
Primum occupat plantas masculinas serius etiam femininas. Caulis 
mycelio infectus e pro pigoo allicit oculos annulo albo tres usque sex 
uncias lato. Serius erumpit mycelium superficiale viridi fuscum in 
zona media annuli albi, et tandem in hoc ctespituli filorum fructifi- 
cantium, capitulis albis. 
Proxime affinis Botryti yarasiticce F. a qua tamen notis adlatis 
satis discrepat. Novam censeo speciem quamquam possibile est eam 
botanicis Indiee orientalis unde Cannabis ad nos venit, notam esse.

Tbe Eev. M. J. Berkeley has recently published a figure of this 
species in the ‘‘ Gardener’s Chronicle,”' of an abnormal form, 
and at that time expressed a doubt that the figure in “ Myco- 
graphia” (Fig. 212) is not the true species. Having had the 
opportunity of comparing a specimen from Mr. Berkeley himself, 
with the specimens consulted in the preparation of that figure, 
we have arrived at the conclusion that there is no specific 
difference between them. The curved paraphyses on which so 
much emphasis was placed, are sometimes present also in P.onotica 
and P. leporina, but in none do they always occur; and even 
supposing then to be curved when fresh, they will become 
straightened as the cup dries. With all deference to such an 
authority, we cannot hold that the difference is sufficient to 
warrant us in regarding the two forms as specifically distinct. 
Had we not adopted a broad view of the limits of species in 
Mycographia,” the large number already figured would have 
been nearly doubled.
