Studies in Entomogenous Fungi. T. Petch. 11g 
and Everhart, North American Fungi, 2nd Series, 3311; Lang- 
lois, 2290; Ellis, New Jersey; Dearness, Ontario, Canada. 
Specimens which have been identified as Sphaerostilbe flammea 
Tul. are not numerous in British Herbaria, and many are in- 
correctly determined. Ellis and Everhart, North American 
Fungi, 2nd Series, No. 3311, Sphaerostilbe flammea Tul., and 
No. 3312, Atractium flammeum Berk. and Rav., are represented 
in Herb. B.M., but neither of these is correct. 3311 has densely 
clustered perithecia in cracks in the bark: the specimens are 
chiefly immature, and the available ascospores are narrow-oval 
or oblong-oval, 6-10 x 2-2°5. 3312isamore immature gathering 
of the same species, and does not bear any Atractium. 
Under Sphaerostilbe flammea, Herb. Kew has “Ravenel, 
Fung. Car. Exsicc., No. 5, 86,” and “Sphaerostilbe flammea 
Tul., Rav. v, 86, sub Atvactium flammeum v. minor, on Acer.”’ 
The latter specimen is ex Herb. Cooke. 
I have examined the following specimens of Sfhaerostilbe 
flammea from Ravenel, which were referred to Nectvia muscivora. 
Specimen ex Herb. Ravenel in Herb. B.M., marked ‘45, 
Sphaeria muscivora Berk., Nov., on Jungermannia growing on 
Acer rub., S.C., H.W.R.’’; this has synnemata clavate, 0-5 mm. 
high, 0-05 mm. diameter below, expanding to 0-25 mm. above, 
or pulvinate, 0-5 x 0:25 mm.; conidia 60-80 x 5-6, nearly 
straight, up to nine-septate, septa obscure and poorly developed, 
usually only three or four and irregularly distributed; conidia 
tend to collapse laterally; ascospores 12-19 x 6-8 yw. Specimen 
ex Herb. Ravenel in Herb. B.M., marked “45 Sphaeria musci- 
vora Berk., Autumno, apud Jungermannia, S.C., H.W.R.,” with 
drawing of ascospore marked “‘-0007 inch long’”’; apparently a 
duplicate of the former; both contain many synnemata but 
few perithecia. Specimen ex Herb. Ravenel in Herb. B.M., 
marked 1156 and spore measurement as above; this has caespi- 
tose collapsed perithecia. Ravenel, Fungi Car. Exsicc., No. 57, 
in Herb. Kew and Herb. B.M.; ascospores 13-17 x 6-8 yp. 
Specimens in Herb. Kew and Herb. B.M., ex Herb. Ravenel, 
“3263, Nectria muscivora Berk., on moss on Acer, St Johns 
(indecipherable), S.C., Apr. 81, H.W.R.’’; perithecia clustered 
in groups up to Imm. diameter, orange red, collapsing cen- 
trally, darker round the ostiolum, pruinose with white granules; 
ascospores 12-17 x 7-8 w; synnemata flattened pulvinate up to 
0-6 x 0-¢mm., or clavate, 0-6 mm. high, 0-25 mm. diameter; 
conidia nearly straight, 85-105 x 6u, up to eleven septate, 
septa obscure; conidia fairly abundant; the pulvinate synne- 
mata bear numerous developing perithecia. Specimen in Herb. 
Kew, marked “‘ Nectria muscivora, Car. Aust.” which is appa- 
rently part of one of the Ravenel specimens with Jungermannia.
