Resembling, when young. Hymenochceie (lendrUka ; spreading 

 widely : peridiiun consisting of branched silky tibrils ; spores 

 •0003 long, 00015 wide." Subsequently it was re-described 

 by Massee as '' Trichosporium apios-porum : Late efifusum 

 fulvum ; hyphis agglutinatis in fasciculos dendritiee radiantes ; 

 conidiisex apice subpyrif ornii ramulorum oriundis, ellipsoideis, 

 minute verrucosis, subhy alinis , 8-9 x 5 ^." In Lister's 

 Monogi'aph it was excluded from the Mycetozoa, but an 

 examination of the specimen in the Peradeniya Herbarium 

 threw no light upon its real nature. The specimen consists of 

 a block of red-brown hypha;, in which are mingled a few 

 hyaline spores and a large number of echinulate, obovate spores, 

 which, as stated in "The Mycetozoa of Ceylon," look exactly 

 like the spores of Fomes lucidus, or rather the Ceylon species 

 which has been supposed to be lucidus. 



A search through Berkeley and Broome's List of the Fungi 

 of Ceylon reveals the fact that Thwaites' 266 provided not 

 only Retindaria apiospora, but also Hymenochceie dendroidea 

 B. & Br. and Ilypomyces chrysostomus B. & Br. The latter 

 was said to be parasitic on a brown feathery mycelium. The 

 reference to Hymenochcete dendritica , in the description quoted 

 al)ove, is an error for dendroidea ; this species was transferred 

 to Thelephora by Cooke (Grevillea. Vlll.. j). loO). 



Thelephora dendroidea has recently been collected again in 

 Ceylon, and its re-discovery has solved the problem of the 

 identity of ReUcularia, apiospora. 



Thelepliftra dendroidea usually grows on the under surface 

 of Fomes anstralis, sometimes spreading to and sm-rounding 

 grasses, &c., in the neighbourhood. In its mode of growth it 

 resemblcK a Thelephora, but as spores and basidia have never 

 lx?en observed, its true position is unknown. Mr. C. G. Lloyd 

 informs me that it occurs in America, usually on Fomes 

 applanutu.'i (which is the temperate form of australis), and that 

 it is equally sterile there. It is generally orbicular, and 

 centrally attached, ])ut it becomes adherent to the lower 

 surface of the Fomes, so that it might be described as 

 loosely adherent. On grasses it encircles the stalk, or 

 runs along projecting from one side. Its upper surface is 

 continuous and nsuallv somewhat nodular, the latter character
