HYPOORELLA AUD ASCHERSONIA. 23& 



retained. The type of Hypocrella Mollii on Premna tomentosa 

 from Java, in Herb. Berlin, contains .small specimens, associated 

 with Hypocrella discoidea ; the description does not include the 

 latter species ; Koorders' measurement of the part-spores ( 15- 1 7 1^) 

 appears to be too large. The type of Hypocrella cretacea v. 

 Hohnel, on Amomiim, Java, is represented in Herb. Kew, Herb. 

 British Museum, and Herb. Berlin ; the part-spores were 8-12 x 

 2 ^ in the specimens examined by me. Hypocrea variabilis 

 Currey, type in Herb. Kew, on Ochlandra, Pegu, is a mixture of 

 Hypocrella Mollii {Aschersonia stage) and Aschersonia badia ; 

 from Cm-rey's description it is evident that he regarded these as 

 young and old forms, respectively, of the same species ; his 

 enlarged figure is not recognizable as either species ; the specimen 

 is mai'ked " Aschersonia " by Massee. Aschersonia confluens P. 

 Henn, on Leucosyces, " Luzon, Manila, 13,647 Warbmg," type 

 in Herb. Berlin, contains one specimen only. Aschersonia 

 phthiuriodes P. Henn., type in Herb. Berlin, on Lepidadenia 

 Wightiana, Java, is typical Hypocrella Mollii {Aschersonia stage) 

 on a black Aleyrodes ; in some specimens the ostiola are green, 

 in others pale yellowish ; this variation has been noted on Ceylon 

 specimens, both colours being fou.nd on the same stroma. Other 

 collections examined include specimens on Citrus decumana, Java, 

 ex Herb. Raciborski ; on Aleyrodes on bamboo, probably Schizos- 

 tachyum, No. 10,838, Province of Bulucan, ex Herb. Bvireau of 

 Science, Philippines, with Aschersonia badia ; specimens associated 

 with Aschersonia badia, on leaves of Dilleniacese, Annam, ex 

 Herb. Patoviillard; on Aleyrodes on teak, Rangoon, ex Herb. 

 Pusa, with Hypocrella discoidea. 



The specimen from Marquesas, recorded by Berkeley and 

 Broome in Fungi of Ceylon, No. 799, stib Aschersonia placenta, 

 and included under that name in Herb. Kew, is the Aschersonia 

 stage of Hypocrella Mollii. 



Collections in Herb. Peradeniya includes specimens on Aleyrodes 

 on Pothos scandens, Ceylon ; on Aleyrodes on a dicotyledon, 

 Ceylon (three gatherings) ; on Aleyrodes on Ochlandra, Ceylon 

 (foiu" gatherings) ; on Aleyrodes on Andropogon muricatus, Ceylon; 

 on Castancpsis sp., Shan States, coll. J. H. Burkill ; on Aleyrodes 

 on teak, Rangoon, with Hypocrella discoidea. Parkin's Ascher- 

 sonia A. 3, p. 37, and A. 1, p. 36, are this species. 



A large series collected on one occasion, on a black Aleyrodes 

 on Ochlandra, Ceylon, presents ciu-ious abnormal forms Some 

 specimens are scutate, i.e., with a thin broad border rising gi-a- 

 diially into the central pulvinate mass, and do not differ from 

 other gatherings. In others the aleyrodid is siu-rounded bj^ a 

 circular or oval, iiTegular, swollen white ring, at a distance of a 

 millimetre or more from the insect. These rings are sterile and 

 up to 4 mm. in diameter, and in some cases adjacent rings coalesce. 

 In some instances a ring of this description surrounds a typical 

 Mollii stroma. It would appear that an extraordinarily luxiu-iant 

 growth of the fungiis has resulted in the formation of a ring round 

 the scale instead of a pulvinate mass over it.
