Thwaites' 313 (B. & Br. 734) in Herb. Peradeniya contains 

 small sethalia, 1 to 1-5 mm. diameter; they probably were 

 originally conical, but they are now flattened. In Thwaites' 

 254 (B. & Br. 735) many have escaped flattening owing to 

 inequahties in the wood ; they are black, either spherical, 

 0'4 to 2 mm. diameter, or conical, about 1 mm. high, and 0*4 

 mm. diameter ; the spores are irregular, apparently not quite 

 mature, ochraceous, 4 to 5 /* diameter. In a recent gathering 

 from Hakgala the aethaha, with one exception, are conical, 

 3 mm. high, 2 mm. diameter at the base, gray or bronze, with 

 black elongated warts, blackish at the base ; the spores are 

 pinkish gray in mass, marked with a faint broken reticulation, 

 5 to 6 /* diameter. This is evidently an " up-country " species, 

 since Thwaites' specimens were collected at Nuwara Eliya 

 (6,600 feet), and the only recent Ceylon gathering is from 

 Hakgala (5,600 feet). 



SUBCOHORT II.— CALONEMINE^. 

 Order I. — Trichiace^. 



Trichia aflfinis, De Bary. 



Fairly common, but usually showing an approach to Trichia 

 persimilis, either in the colour of the sporangium, or in a 

 slightly broken reticulation of the spores, or sometimes in 

 having spinulose elaters. The sporangia are ochraceous 

 yellow, or golden, or red-brown, sometimes somewhat irides- 

 cent ; but the red- brown sporangia have the spores and 

 elaters of affinis, not of persimilis. In one gathering the 

 sporangia are grayish ochraceous, iridescent ; the elaters are 

 golden yellow, and contrast strongly with the spores, which 

 are umber in mass and yellow- brown when magnified. In 

 several gatherings the sporangium wall contains yellow 

 spherical granules. The number of bands on the elaters is 

 usually four. The spores are generally 12 to 13 /' diameter,
