heating with chloral hydrate. The asci are cylindric and 
eight-spored, without paraphyses. The ascospores are elliptic, 
obtuse, one-septate, not constricted, hyaline or slightly brownish, 
Q-12 X 4°5 pb. 
The above details are taken from Zimmermann’s description. 
No specimens of Lisea on scale insects have come under my

CALONECTRIA. 
Calonectria coccidophaga Petch. 
This species, specimens of which were kindly submitted to 
me by Mr C. C. Brittlebank, occurred on Planchoma acaciae, 
on Acacia sp. at Warburton, Victoria, April 30, 1917 (Coll. 
J. Farrell). 
The perithecia are clustered, in pulvinate groups up to 2 mm. 
diameter, on a fairly well-developed parenchymatous stroma 
(Plate IV, figs. 3, 4). The cluster appears black, but on detaching 
the perithecia, they are found to be black in the upper part, 
but pinkish-yellow below, and the stroma is yellowish. From 
the colour of the perithecium when immersed in water, it is 
probably very dark red when fresh. The perithecia are globose, 
about 0-4 mm. diameter, pruinose, naked at the apex. In some 
specimens, the apex is papillate, but in other examples it is 
flat and discoid with a punctiform ostiolum. The wall in section, 
and internally, is rose-red (Plate IV, fig. 3); it is very thick, and 
when mounted the outer layer is vinous or purplish-red while 
the inner layers are yellowish-white. It has a somewhat horny 
appearance in the dry specimens. The asci are clavate, eight- 
spored, with spores biseriate above, uniseriate below, 120- 
I40 X 14-16, and are accompanied by stout paraphyses, 
branched above, with granular contents. The spores (Plate V, 
fig. 7) are oblong-oval or subcymbiform, straight or curved, 
with obtuse ends, three-septate, sometimes constricted at the 
septa, especially at the median septum, 22-34 « 8-gp. Occa- 
sionally a spore is four-septate, one-half being two-septate. 
Immature spores in the ascus, though with developed septa, 
may be fusoid and only 5 w broad. 
With the foregoing, there occurred a conidial stage which is 
undoubtedly Microcera tasmantensis McAlp. Mr Brittlebank has 
kindly submitted to me the type of Microcera tasmaniensis 
McAIp., on a scale on Eucalyptus, Tasmania (A. M. Lea), Aug. 8, 
Igor, and that of Microcera Mytilaspis McAlp., on Mytilaspis 
sp., on Hymenanthera dentata, Ivanhoe, Victoria, Sept. 14, 1903. 
On comparison, it appears that these two species are identical, 
the first being a younger development of the second. The type 
of Microcera Mytilaspis, though at first sight different from
