REPRODUCTION OF THE ASCOMYCETES. 
opinion at any rate, some of the characters of the perithecia proper 
to the Ilypomyces. The species, the conidia of which are pluri- 
locular, lead us up to the curved spores of the Selenosporium, Stil- 
hum (partim), and Atractium, Fusisporium^ Fusarium, the analogy 
of wliich, with the Hypomyces, is evident ; a general appearance, 
the tint of the plasma often coloured, the disposition of the spores, 
indicate an incontestible kindred. It is in consequence of this 
analogy that M. Tulasne, having been able to attach many of these 
conidial forms to their ascophorous form, has placed these last in the 
great group of Nectriacei, by the side of the Hypomyces. It is 
thus that according to M. Tulasne, the Atractium Jiammeum, Berk, 
and Ravenel., is the conidial form of the SphoerostUbe flammea, 
Tub; the A. cinnaharinum, Mont., belongs to the Sph. cinna- 
harina, Tub ; the Fusisporium Buxi returns to the Nectria Rus- 
seliana, Mont., etc. I have been able, in a prolonged culture 
during many weeks, to verify the first of these facts. 
This consanguinity has already been indicated by the illustrious 
French mycologist, and that which has just been said is with a 
view to recall it. He has shown the relation which allies all these 
forms ; but in continuing the study of the Mucedines one can 
foresee that there are a certain number of species and, perhaps, 
genera which we ought to draw closer to one another, ami thence 
deduce their place in the series. 
Without appealing to any new considerations, one can remark the 
extreme analogy of certain forms of Mucedines with the Hypomyces 
of which we have just treated ; it is thus that Verticilliiim, Acros- 
talagmus, Acrocylindrium, Cylindrophora, Acremonium, of which 
many forms are figured, constituting probably the representatives of 
the spermatiophorous arbuscles of species of Ascornycetes more or 
less allied to the Hypomyces ; it is the same with Dendrocliium, 
one of the species of which probably belongs to the Sphcei'ostilbe 
aiirantiaca, Tub 
In support of this way of looking at the matter, one can cite 
the opinion of M. Bonorden ; he likewise has proved the analogy 
of Veiticillium with the spermatiophorous arbuscles of the Ascomy- 
cetes, and thought he might consider his Verticillium ruberrimum as 
the spermatiophore form of Trichothecium roseum, Lk. M. de Bary, 
being assured that the spores, very small besides, still possessed the 
faculty of germinating, has disputed this assimilation. He has 
contended also that the Verticillium was a form of the Tnchothe- 
cium — an opinion which appears in fact little admissible. 
At the present time, and for some other reasons, one can retake 
the opinion of M. Bonorden and assimilate these small arbuscles to 
those of the Hypomyces, and, in consequence, to the spermatio- 
phorous filaments of the Ascornycetes. Figure 11 of plate 10 
represents a species developed in great abundance upon some 
decomposed leaves of the Vitis riparia, at Bordeaux, in the 
month of November, 1873 ; at the same time, upon the same 
sub-stratum, was found, in great abundance also, the spores of a
