 The type specimen of Hypocrea viridans in Herb. Kew, from 

 Cuba, is on a black Aleyrodes on Gesnerla ; Berkeley described 

 it as pale gray, becoming green. This green colouration is not 

 uncommon in the case of pale-colovired species ; it has been 

 noted in Hypocrella phyllogena, Hypocrella MolUi, &c. The cause 

 of this change has not been ascertained, but it appears to depend 

 on some parasitic or external agency. It is, however, fairly 

 constant in this species. Hypocrea amazonica Cooke, in Herb. 

 Kew, from Brazil, contains this species, among others ; the 

 specimens are green, up to 1 • 5 mm. diameter, slightly crenulate, 

 white internally, with large, brown, oval ostiola. The type of 

 Aschersonia disciformis ex Herb. Patouillard, on Cestrum, Ecua 

 dor, is also on an Aleyrodes ; most of the specimens are crenulate, 

 grayish-green, usually depressed in the centre, without a hypo- 

 thallus. Tliis species is attributed to Aschersonia oxyspora Berk.
