BEVI&IONS OF CEYLON FUNGI. 281 



probably depending upon inequalities in the under surface 

 of the Fomes. Its substance is soft and loose, being built 

 up of radiating, f em-like, superposed strands of myceUum, 

 entirely red-brown. The lower surface is beautifully adorned 

 with repeatedly-pinnate veins radiating from a common 

 centre, like the fronds of a large Hypnum : to this feature 

 the fungus owes its name. 



In Berkeley and Broome's specimens, and in those recently 

 collected , the whole of the tissue of the fungus is crowded with 

 spores ; but these are not the spores of the Thelephora, but 

 the spores of the Fomes, which have fallen while the Thelephora 

 was growing and have been entangled in the loose tissue. 

 Further, both the recent specimens and those which Thwaites 

 gathered are parasitized by Hypomyces chrysostomus. 



When Berkeley and Broome received Thwaites 266, they 

 separated part of it as the type of Thelephora dendroidea, and 

 part as the type of Hypomyces chrysostomus. But a third 

 part they named Reticularia apiospora. The latter is part of 

 the thallus of the Thelephora, containing the spores of Fomes 

 australis and the conidia of Hypomyces chrysostomus. 

 Massee's measurement is that of the spores of the Fomes, but 

 they are not subhyaUne. 



90. — Eurotium dipiocystis B. & Br. 



This was described by Berkeley and Broome (Jour. Linn. 

 Soc, XIV., p. 137) as follows: — " Irregulare, subglobosum vel 

 elongatum, flavum, demum aurantiacum ; ascis globosis 

 pedunculatis e floccis decumbentibus oriundis ; sporidiis 

 octonis ellipticis (No. 291). The ascus itself is soon absorbed 

 as in the genus Badhamia ; the peduncle is long and flexuous, 

 several arising from decumbent branched threads. This may 

 possibly be a distinct genus ; but we have scarcely sufficient 

 materials to decide." 



The supposed co-type of this species (Thwaites 291) in the 

 Peradeniya Herbarium contains only a sterile sclerotium 

 resembling that which I have previously referred (in error) to 

 Sclerocystis coremioides. As it seemed impossible that species 

 should have furnished the description quoted above, the
