REVISIONS OF CEYLON FUNGI. 393 



hence the gills separate from the stalk m a pseudo-collar when 

 old. The spores are white, broadly oval, 10-14 x 7-8 /i, with 

 some globose spores 6 n diameter. Cystidia not found. 



When decay sets in, the pileus becomes pale ochraceous or 

 brownish ; hence Berkeley and Broome's name " subaurantia- 

 cus,'' which was derived from the dried specimen. The colour 

 of " ignobilis " was taken from the figiu-e, and therefore is more 

 correctly given as " alhidus." The specimens which develop 

 in dry situations have some resemblance to Marasmius, but it 

 is evidently too readily putrescent to be included in that genus. 

 Nor can it be placed in the problematic Heliomyces. I have 

 included it, somewhat doubtfully, under Oudemansiella. It 

 has exactly the structure of Oudemansiella apalosarca, agreeing 

 in the following points. It has a fibrillose universal veil. 

 The internal tissue of the pileus is subgelatinous when moist, 

 hence it is translucent or opaque according to weather condi- 

 tions. Tlie hymenium is continuous from gill to gill over the 

 stalk. The gills have a thin edge when dry, but if they are 

 moistened the tramal tissue absorbs moisture and the hymenial 

 layers on either side of the gill separate ; they then have thick 

 edge with a translucent line of subgelatinous tissue along the 

 middle ; tliis corresponds exactly witli the formation of the 

 thick edge of the gill in Oudemansiella. It differs from Oudem- 

 ansiella, as redefined by von Holinel, in the shape of its spores ; 

 but it is questionable whether the shape of the spores, in agarics, 

 is of generic importance.

Thwaites' 751 was sent with two drawings, one representing 

 the mature fungus and the other a young stage ; the former 

 was named Omphalia anthidepas, and the latter Cantharellus 

 stolonifer. Hygrophorus prasinus is a, different gathering, but 

 the drawing is' a good representation of the immature form,
