Studies in Entoniogenous Fungi. T. Fetch. T19 



I have not seen the t\-pe specimen from Java, nor Rechinger 

 5274, nor the specimen recorded by Parkin (p. 19), on an Aley- 

 rodid on a jungle tree, Pusella, Ceylon. February' 1S99. 



Immatiure examples of the perithecia of this species are not 

 as tall as the mature form, and the apex, as noted by Parkin, 

 is dark purple, almost black. The characteristic yellow sub- 

 translucent apex apparently is not developed until the peri- 

 thecium is nearly mature (Plate II, fig. 3). 



The stroma is looser than in T. rubra. The exterior hyphae 

 are flexuose, contorted, thick- walled to almost sohd, 3-5 /x 

 diameter, \-i\-id purple-red to almost hyaline. In some hyphae 

 the colour is confined to the contents, the thick wall being 

 hyaline. A few line h\-phae, 0-5 /x diameter, are present. Here 

 and there, the thick h\-phae are fused together side by side in 

 small patches. The h\*phae appear to be more rigid than in 

 T. rubra, and they tend to break up into short lengths; they are 

 almost smooth, or minutely pitted. In the interior of the stroma 

 the h\-phae have more deeply coloured walls. At the base of the 

 stroma, thick-walled hyahne h\-phae occur, which are encrusted 

 \rith granules. Some thick-walled, repent M-phae in the h\"po- 

 thallus are minutely spinulose. 



The perithecia usually have a thick weft of h^-phae at the 

 base and up to two-thirds their height, which makes them 

 appear conoid. These h\-phae are \'i\-id purple-red. 



\Vhen a stroma has turned bro\Mi, the h\-phae are pale yeUow 

 when mounted; the colour is contained in the cell wall, not 

 concentrated in the plasma. The h\-phae appear to bear more 

 granules than those in the purple-red forms. Fig. 5, Plate II, 

 shows a stroma which is changing colour from the centre out- 

 wards. 



In one collection from Hakgala, April 1917, on Murraya 

 exotica, some stromata are pure white, %rith dull broNMi peri- 

 thecia, yellow-bro\\Ti at the apex, and traces of purple-bro\Mi 

 in the stroma round the perithecia. The structure of the stroma 

 is different from that of the normally white Ceylon species. 



^^^len the stroma turns bro\Mi, the perithecia may remain 

 purple-red; and if the perithecia also become bro\Mi, traces of 

 purple-red usually remain in the Mphae at their bases. The 

 specimen from the Seychelles has stromata varying from San- 

 ford bro\\'n to pale purple-bro\\Ti. Their h\-phae are red-bro\\*n 

 to almost hyaline, strongly encrusted \rith red-broN\'n granules, 

 while broNSTi amorphous masses occur among them. The peri- 

 thecium wall retains traces of purple-red at the base. I had 

 assigned this specimen to T. brunnea v. Keissl., but on com- 

 parison %\'ith the other available specimens it appears to be 

 undoubtedly T. luteorostrata, and I am of opinion that T. brunnea 

 was based on a similar specimen.
