narrow byssoid stroma, pallid or pale rose, round the scale. 
The synnema is about a line high, with a deep red head con- 
sisting of linear lanceolate, curved conidia, three- to five-septate, 
65 x 6p. The perithecia arise at the base of the synnema, or 
on stromata which lack synnemata; they are minute, globose, 
obtusely and very shortly papillate, very smooth, shining red, 
fleshy and fragile, collapsing when dry, clustered in groups of 
three to five. The asci are cylindric, 60-80 x 6:5, obtuse, 
subsessile, eight-spored. The ascospores are ovate, subhyaline, 
one-septate, somewhat constricted at the septa, ends obtuse,

son. (Mycologia, 1, p. 180) regards Sphaerostilbe coccophila 
Tul. as identical with Nectria subcoccinea Sacc. and Ellis, and 
suggests that it is also identical with Nectria auranticola B. 
and Br. and Nectria aglaothele B. and C. He states that the 
synnema consists of a short stout stalk with an orange head, 
the conidia being straight, or more often curved, fusiform, three- 
to seven-septate, 50-90 x 5-6 p, occasionally shorter; and that 
the perithecia are more or less caespitose, bright orange, with 
a prominent, rather acute ostiolum, and contain cylindrical asci, 
75 x 8-10 p, with elliptical or subelliptical spores, 12-18 x 7-9 p. 
He cites the American specimens, Ellis, North American Fungi, 
No. 1333 (issued as Nectria subcoccinea); Ravenel, Fung. Car. 
Exsicc., No. 57 (issued as Nectria muscivora Berk.) ; and Hume, 
Florida, No. 39. The dimensions given for the ascospore give 
occasion for doubting the identity of the fungus described by 
Seaver with that described by the Tulasnes. 
Von Hoéhnel and Weese state that Nectria subcoccinea Sacc. 
and°Ellis (1882) is identical with Nectria Colletiae Rehm (1898) 
and Nectria coccidophthora Zimm. (1901) from the descriptions ; 
and again that Nectria Colletiae Rehm is identical with Nectria 
subcoccinea Sacc. and Ellis, and, fide Seaver, with Sphaerostilbe 
coccophila Tul. 
In order to clear up the synonymy suggested by the authors 
cited, an examination has been made of as many as possible 
of the type specimens, or of authentic specimens, of the species 
referred to. Nectria Colletiae Rehm is the only species not 
available in Herb. Kew, Herb. British Museum, or Herb. 
Peradeniya. The conclusions arrived at are stated here briefly; 
reference to the specimens examined will be made when dealing 
with the species individually. . 
To differentiate accurately between the different species of 
Microcera it is necessary to have the perithecial stages. In the 
conidial stage, they are all very similar, and though it appears 
possible to distinguish the conidia of Microcera coccophila from 
those of Microcera aurantticola when both have been collected
