Citrus, Ceylon. On Aspidiotus aurantit on Mulberry, Ceylon 
(five collections). On Aspidiotus sp. on Cycas, Ceylon. On a 
diaspid (?) on Thespesia, Ceylon. On Mytilaspis citricola on 
Citrus, Ceylon (three collections). On ? Porococcus, on Palmyra, 
Ceylon. On Lepidosaphes sp. on Pepper (Piper nigrum), South 
India (C. A. Barber, 1905). On Lepidosaphes sp. on Citrus, 
Madagascar. Conidial stage on Aspzdiotus and Lepidosaphes, 
and perithecial stage on Lepidosaphes, on Citrus, Dominica. 
In the specimen from Dominica, the synnemata are small, 
and the conidia measure only 70-92 « 5-6: most of them are 
three-septate, a few five-septate. The asci are 74-80 x 7, and 
the ascospores 10-14 x 4-6. The perithecia are identical with 
the Ceylon form of Nectria aurantiucola, and the small, curved 
Fusarium spores occurred with them. 
A Sphaerostilbe, parasitic on scale insects in Japan and 
Formosa, has been recorded, with some doubt, by Miyabe and 
Sawada, as Sphaerostilbe coccophila Tul. I have been able to 
examine the following specimens, ex Herb. Sapporo. 
On ascale on apple trees, Tsukisappu near Sapporo, October 5, 
1907. In this, some synnemata are suberect, with a short stout 
stalk, 0-2 mm. diameter and 0-4 mm. high, expanding into an 
ovoid head, 0-3 mm. diameter, and 0-4 mm. high, pointed above; 
the stalk in these is dark red, subtranslucent, and the head pale 
yellowish, the latter colour being due to the disappearance of 
most of the conidia. Other synnemata are almost sessile, ovoid, 
or sometimes merely pulvinate, dark red. The sheath divides 
above into teeth, but the teeth break up above into separate 
hyphae, as a rule, as long as, or longer than, the conidiophores. 
The conidia measure 84-100 x 5~7 pw, and are up to nine-septate, 
nearly straight or curved at the tips, one end more obtuse than 
the other. When examined under a low power the conidia are 
distinctly yellowish. 
In another gathering, on a coccid on Ficus Wightiana, Sozan, 
Formosa, May 1911, the synnemata are mostly stalked, but the 
heads have been eaten off by insects. 
In a collection, on coccids on Citrus nobilis, Shimpo, Formosa, 
May 7, 1910, the synnemata are generally small, pulvinate, 
blood-red masses at the side of the scale, sometimes several 
confluent and forming a fringe at one end. 
Similar synnemata occur on scale insects on Citrus nobilis, 
Taihoku, Formosa, April 25, 1911. Some of the sessile pulvinate 
synnemata are up to 0-4 mm. long and 0-2 mm. broad. Stalked 
forms, with stalks up to 0-3 mm. high and o-2 mm. diameter, 
also occur in this gathering. The conidia are 80-96 x 6-7 p. 
Perithecia appear to be rare in the Formosan collections. 
Miyabe and Sawada state that they have only found them once,
