This is the common species on Lecanium in Ceylon, and appa- 

 rently in the Eastern tropics generally. It resembles Hypocrella 

 cavernosa Moll, in its tubular pycnidia, but this feature is not 

 constant. The Hypocrella stromata, as a rule, contain pycnidia 

 also, but the species is most frequently found in the Aschersonia 

 stage, i.e., with pycnidia only. 



In the type of H. Reinecklana in Herb. Berlin, on petioles, 

 stems, and leaves of some climbing Rhaphidophora, Upolu, the 

 stromata are ochraceous, closely dotted with brown perithecial 

 ostiola, which do not project ; they are about 2 mm. diameter, 

 not 3 centimetres as stated by Hennings ; the peritheca are 

 arranged regularly round the periphery (in section), and are 0' 25- 

 0*3 mm. deep, and 0"12-0*15 mm. diameter; the part-spores, 

 in the ascus, measure 6-8 X 1 [x ; the stromata a' so contain 

 pycnidia, 0*2 mm. diameter and 0*3 mm. deep, lobed below ; 

 the pycnospores are not quite mature and measiu-e 6-10 0"75-ljx, 

 In Hypocrella Pernettyse, on leaves of Pernettya repens, Java, 

 type ex Herb. Patouillard, the specimens are now clay-coloured ; 

 they are smooth and subglobose but some have been eaten away 

 at the top bj' insects ; the stromata contain pycnidia as well as 

 perithecia ; they are associated with a Lecanium. 



Aschersonia marginata is represented in Herb. Kew, Herb. 

 British Musemn, and Herb. Berlin by parts of the type collection, 

 " Plants of the Hawaiian Islands, collected on the Island of Oahu, 

 in and on the slopes of Makiki. On Pisidium Guayavc, 1945." 

 These are on a Lecanium. In all the collections the specimens are 

 old and black ; the pycnidial orifices are scattered, most of them 

 near the base, with the edge recurved and lacerated, as is tisual 

 in old specimens ; the stromata are only "margined" when they 

 are situated eccentrically on the scale, so that the latter projects 

 on one side. The potash extract is bi'ownish-yellov\ . The 

 pycnidia are oval or tubular, some of the latter penetrrting almost 

 to the base of the stroma. The pycnospores measure 7-10 x 1 ' 5 |j, ;
