HYPOCRELLA AND ASCHERSONIA. 225 



Distribution. — Philippines, in Herb. Sydow. 

 Figures. — Plate 3, fig. 54, specimen ex type, x 8 ; Plate 4, fig. 

 18, section, x 4. 



Hypocrella nectrioides Thaxter in Utt. — Stroma up to 2 mm. 

 diameter; basal part plano-convex, up to 0'3 mm. thick, 

 bearing numerous clustered, ovoid or turbinate processes, 0*6- 

 0*8 mm. high, 0* 5-0* 7 mm. diameter, minutely tomentose, the 

 apices of the j)roc esses becoming glabrous ; rosy orange when 

 fresh (Thaxter), white, slightly translucent, in herbarium 

 specimens. Perithecia single in each process, narrow flask- 

 shaped, up to 0*5 mm. deep, 0*2 mm. diameter, opening 

 rather widely when mature. Asci (part-spores mature) 

 300 X 14 ji. Part-spores narrow-oval, ends obtuse, 8-12 X 

 2-5-3 [;.. 



On a scale insect on Pentaclethra sp., St, Ann's Valley, Port 

 of Spain, Trinidad (coll. R. Thaxter). 



In the available specimens the stromata have developed on a 

 scale insect on the rachis of the Pentaclethra leaf, and have in 

 consequence encircled the rachis, so that the processes project in 

 all directions. If developed on a flat surface it would no doubt 

 closely resemble Hypocrella Aniotni, froni which it differs chiefly 

 in the shape of the spores and the absence of a scarious hypo- 

 thallus. On the other hand, it resembles some forms of Hypo- 

 crella Racihorskii, and it might prove, when the Aschersonia stage 

 is known, to belong to the Aleyrodiicolse. 



Hypocrella turbinata (Berk.) Petch, Ann. Perad., V., p. 535 

 (1914). — Stromata simple, subcylindric, about 1*5 mm. 

 diameter and 1 mm. high, expanded at the base into a stout 

 horizontal margin up to 0*25 mm. broad, upper surface 

 truncate, sometimes plane, more usually concave, minutely 

 umbilicate in the centre ; or egg-cup shaped ; or compound 

 with a solid hemispherical or convex basal stroma up to 4 mm. 

 diameter, from which arise several (up to 12) cylindric or 

 obconic processes with a concave upper surface ; white, 

 becoming black when old, minutely tomentose; moderately 

 hard. Pycnidial orifices on the concave disc, sometimes 

 solitary and central ; pycnidia irregular, branching internal^ ; 

 pycnospores narrow-oval, ends pointed, with apparently 

 solid, conical tips about 2 \i. long, 10-13 X 3*5-4 [jl. Peri- 

 thecia flask-shaped, 440 ^Ji, long, 150 \i. diameter ; asci 210 X
