with a short, thick pedicel, eight-spored, with biseriate spores; 
but while some are thick-walled, 116-134 x 20-24 p, and show 
clearly the septate ascospores, others are thin-walled, slightly 
thicker at the apex, 170-190 x 24, and appear at first sight 
to be filled with a plasma which contains innumerable large 
guttae, the walls and septa of the ascospores being obscure. 
The paraphyses are filiform, branched and irregularly flexuose 
at the tips, rather scanty, and, as a rule, shorter than the asci. 
The ascospores are clavate, sometimes acute at the apex, usually 
strongly attenuated below, 8- to 14-septate, not constricted at 
the septa, hyaline, 64-82 x 7-9 p. 
The sporodochia have a shortly columnar base, up to 0:3 mm. 
diameter and 0-2 mm. high, brownish yellow, becoming brown, 
constricted above, with generally a flat white head, up to 
o-4mm. diameter. Sometimes the head is conical. They are 
sometimes arranged close together at the margin of the scale, 
and form a continuous border on one side. The conidia are 
borne in clusters of 2 to 4, and are narrow-cylindric, usually 
with long acuminate tips, multiseptate, 60-190 x 7-8 p. 
This species differs from Podonectria Aurantu (O. tetraspora) 
in the colour of the perithecia, the thin perithecial wall, and the 
spreading teeth. An examination of Broome’s specimen of 
Nectria aurantiicola B. and Br., now in Herb. British Museum, 
showed that it contained this species in addition, but it is not 
included in the description of the former. 
Tetracrium rectisporum (Cooke and Massee) Petch. 
In Grevillea, xvi, p. 4 (1888), Cooke and Massee described 
Microcera rectispora, on a coccus on Citrus from Australia. It 
had straight, multiseptate spores, up to 200p long. Subse- 
quently, Cooke, in Vegetable Wasps and Plant Worms, stated 
that this species did not differ much from Microcera coccophila, 
but he had described it as a new species in deference to the 
view that minute differences in the spores were of specific value. 
Cooke and Massee’s description of the spore suggests Tetracrium, 
and that is confirmed by an examination of the type specimen. 
The type in Herb. Kew consists of three small pieces of bark; 
there are no sporodochia present, but examination under a low 
power shows that the bark is covered with scattered, detached, 
triad spores of Tetracrium. Curiously enough, this is the only 
gathering of Tetracrium or Podonectria known from Australia. 
Consequently it is uncertain to which species of Podonectria 
Tetracrium rectisporum should be assigned.
