Studies in Entomogenous Fungi. T. Petch. 145 
Von H6hnel has raised objections to Seaver’s genus Scoleco- 
nectyia on other grounds. In 1902, Hennings instituted the 
genus Tetracrium for a conidial fungus found on scale insects 
on the leaves of orange in Brazil. Von Hohnel has examined 
the type specimen, and finds that this is identical in structure 
with the conidial stage of Ophionectria coccicola (Fragmente zur 
Mykologie, x1, p. 27). Hennings’ species was named Tetra- 
crium Aurantii, and von Hohnel names the conidial form of 
Ophionectria coccicola, Tetracrium coccicola. But von Hohnel 
found perithecia of the same character as Ophionectria coccicola 
in the type specimen of Tetracrium Aurantit, and these he re- 
gards as belonging to the genus Puttemansia Henn. (1902). 
According to von Hohnel, Scoleconectria is equivalent to 
Puttemansia, both being Ophionectria provided with a stroma. 
This again overlooks the fact that the type species of the genus 
Ophionectria has a stroma. 
Puttemansia was described by Hennings as a genus of Disco- 
mycetae, the type species being Puttemansia lanosa. The type 
specimen has been re-examined by von Hohnel, who stated in 
his first communication on the subject (Fragmente zur Myko- 
logie, XII, p. 23) that it was a stromatic Calonectria, and equi- 
valent to Scoleconectria Seaver, the latter genus including species 
with long, multiseptate spores, and others with elliptic, threc- 
septate spores. 
According to von Hohnel (oc. cit), Puttemansia lanosa builds 
a parenchymatous stroma within the leaf, which bursts through 
the epidermis, and forms a superficial, white, external stroma, 
on which the perithecia are produced. The perithecia are oval, 
or almost pyriform, 200-280 pw high, 350-420 p broad, generally 
immersed in the stroma to one-third, or one-half, their height, 
and often fused together laterally. The superficial stroma is 
parenchymatous. The perithecial wall is 40-60 » thick, rough 
with projecting groups of cells, and clothed with a woolly 
covering of thick-walled, septate, obtuse hairs, 300-500 » long 
and 5-6-5 « diameter. 
Hennings stated that the stromata were “‘villo albo omnino 
tectis,’’ and described the hairs of the perithecial wall as rigid, 
simple, hyaline, septate, obtuse at the apex, 200-400 x 5-6 p. 
The asci were clavate, apex rounded and obtuse, thick-walled, 
120-140 x 18-20, furnished with filiform, branched, para- 
physes. The spores were oblongo-fusoid, three-septate, 40-50 x 
7-8 pw, with a curved basal appendage, 15-20 x 3p. 
Von Hohnel states that there may be an appendage at one 
or both ends, but that these appendages are hollow continua- 
tions of the end cells, not solid ciliae as in Paranectria.
