They examined Desmaziéres’ specimens, Plantae Crypt. Gallicae, 
ed. altera, fasc. xxvul, Nos. 1350 and 1750, and, in the approved 
modern fashion, had obtained specimens from the type locality. 
With these they correlated specimens from Florence, on Laurus 
nobilis, which exhibited both the conidial and the perithecial 
stages. The latter had been issued by Rabenhorst in Herbarium 
Mycologicum (Ser. nova, t. 111 (1860), Nos. 262 and 269) as 
Nectria episphaeria Tode and Microcera coccophila Desm. re- 
spectively. The type locality for the perithecial fungus is there- 
fore Florence, not France as usually stated. 
The Tulasnes’ description may be summarised as follows. The 
fungus produces beneath the scale a pallid, or pale rose, fleshy 
stroma, paler and sparingly byssoid at the edge, which emerges 
and forms a narrow unequal margin round it. From this there 
arises a simple, thick, obtuse clava, about a line high. There 
is usually only one clava, rarely several. The apex is more 
deeply coloured, red, and bears, in a compact mass, curved 
linear-lanceolate conidia, 65 x 6-5 y, three to five septate, borne 
singly on slender conidiophores. The perithecia appear later, at 
the base of the clava, or on the margin of the stroma, the clavae 
being wanting or aborted; they are small, globose, obtusely and 
very shortly papillate, sessile, very smooth, shining red, fleshy 
and fragile, in groups of three to five, somewhat collapsed when 
old. The asci are linear-cylindric, 60-80 x 6°5 u, obtuse, sub- 
sessile, eight-spored, thin-walled; paraphyses are lacking (para- 
physes vulgo quasi omnino desiderantur) ; the spores are smooth, 
muticate, subhyaline, often obliquely monostichous, ovate, 
straight, 10 x 5p, equally medially septate, and somewhat 
constricted. 
It was noted that in Roberge’s specimens from Caen several 
clavae might arise from the edge of the same scale, but in the 
specimens from Florence the conidial stage was much rarer. 
The Tulasnes placed the fungus in their genus Sphaerostilbe, 
as it had a Nectria perithecial stage and a Stilboid conidial 
form. They stated that the Roberge specimens exhibited clavae 
which exactly resembled the true Sti/bum of Tode, and added 
that the clava of Microcera imitated exactly Stilbum flammeum 
Berk. (Atractium flammeum Berk. and Rav.), in its form and 
the slenderness of its filaments, which were united by short 
isthmuses (ladder connections) and separated into a few straight 
branches. In their earlier note, they say that Microcera differs 
little from Atractium. 
For the Tulasnes, then, Microcera was a Stilbum with long 
curved Fusarium spores. They were somewhat scornful of 
Desmaziéres’ velum and his comparison with the phalloids,
