Aschersonia Suzukii M i y a b e et Sawada, sp. nov. 
(PI. VI. fig. 16-23.) 
Aschersonia Aleyrodis X i s h i d a, Diseases of Orange-trees, p. 80. 
Stroma scattered or more or less clustered, ramicolous or amphigenous, 
cream to cinnamon colored, hemispherical, subspherical, conico- or subtrun- 
cato-hemispherical, smooth, then irregularly verrucose, 1-4 mm. in diame- 
ter, marginate around the base, with rather thick light colored hypothallus, 
interior similarly colored, sclerotioid composed of mycelium 3 - 6/x in diameter. 
Pycnidia 4 - 16, immersed in the stroma, iri*egular in shape, 130-270/x in 
diameter, and opening by small poi’es and slits on the surface ; conidiophores 
filiform, simple or sparsely branched, densely packed together, continuous, 
22 — 5 6/i x 1 ft. ; stylospores fusiform, continuous, mucilaginous, hyaline or 
light orange-colored, acute at both ends, 8 - 11// x 2.5 - 3.5/x. Papaphyses 
wanting. 
Hab. Parasitic on Coccus longulus Doug 1. infesting the living leaves 
and branches of Citrus nobilis L o u r. and Fagara nitida Roxb. 
Formosa : Ako, on Citrus nobilis (R. Suzuki, Oct. 28, 1908). Roku- 
masan, Kagi, on Citrus nobilis (Y. Nambu, Nov. 26, 1909). Tennaiho, 
Taihoku, on Fagara nitida (Y. Fujikura, Oct. 3, 1911). 
Remarks. Our fungus is very colosely related to Aschersonia Eugeniae 
K o o r d. (14), parasitic on a scale-insect on the living leaves and branches 
of Eugenia in Java. 
The points of difference between the Javanese and Formosan forms 
are as follows : — 
1. In the shape and length of conidiophores. In our form, the conidio- 
phores are longer, and are simple or sparsely branched, gradually tapering 
toward the tip and densely packed together, and are not fusiformly swollen 
at the tip, and not so loose nor uniformly simple as they are represented 
in the Ko order’s figures. The mode of branching of the conidioplioi’e is 
not constant. It is more often dichotomous apparently in a sympodiul 
manner or rarely trichotomous. (PI. VI. fig. 22 - 23). 
2. In the color of the stroma, our fungus is cream-colored when young,
