MYCETOZOA OF CEYLON. 349 



showing on the hemisphere ; one sessile sporangium was 

 entirely yellow. A gathering from Hakgala has short conical 

 stalks, opaque at the base, clear orange above, up to * 75 mm. 

 high, arising from large circular hypothaUi ; sporangia 0*6 to 

 0*8 mm. diameter, almost flat, supei'ficially resembling D. 

 clavus ; columella white ; capillitium colourless with numerous 

 bead-like thickenings ; spores 7 /* diameter. One gathering 

 of var. xanthoyus has spores 10 to 12 /* diameter. A small 

 group wliich grew on a dead pahn frond at a lieiglit of about 

 15 feet from the gromid has short, dark, opaque stalks and 

 suggests D. farinaceum var. minus, but the colmneUa is white, 

 filled with small nodules of lime ; the examples previously 

 described show that D. nigripes var. xanthop'us sometimes has 

 a stalk which contains refuse matter, and is consequently 

 opaque, in the lower haK, and it would therefore seem 

 preferable to regard these last-mentioned specimens as forms of 

 D. nigripes in which this feature is more strongly developed, 

 since typical Didymium farinaceum has not been found in 

 Ceylon. Vars. genuinum, eximium, and xanthopus of D. 

 nigripes all occur in Ceylon, the last-named being the 

 commonest form.

 Didymium effusum. Link. 



Didymium squamulosum, Fr., in B. & Br., Fungi of Ceylon, 

 No. 1189. Didymium neglectum, B. & Br., Fungi of Ceylon, 

 No. 747. 



Berkeley and Broome's specimens named D. effusum, Link, 

 Fungi of Ceylon, No. 755 (Thwaites' 1024), consist of two 

 pieces of wood bearing a minute hyaline fungus with hyaline 

 spherical spores, apparently a Sphseronema. D. effu^sum is 

 common in Ceylon on dead leaves, sometimes also on tree 

 trunks. 



Peradeniya, Hakgala, Pattipola, &c. 



Didymium anellus, Morgan. 



Taken on four occasions at Peradeniya. In a gathering on 

 dead leaves the plasmodiocaips are gray, flattened, circular, 

 up to 1 mm. diameter, or elongated, winding, and branching, 

 up to 8 X 1 mm. , covered with lime crystals which consist of 

 amorphous masses with projecting points ; wall membranous,
