BERKELEY's TYPES OF FUNGI. 471 
thick and fleshy, becoming thin towards the incurved margin, 
somewhat gelatinous when moist, 2-5 em. across; disce smooth, 
pale brown; externaly and the margiu densely clothed with 
sooty-brown, eylindrieal, obtuse, wavy, septate hairs, 200-300 x 
7-8 u, more or less intermixed, and forming a felted mass; 
hypothecium and excipuluim formed of contorted and interwoven, 
branched, hyaline hyphe, about 3 » diameter, and embedded in 
mucilage; these become thicker, brown, and more closely com- 
pacted to form the cortex, and run out into the external hairs; 
asci cylindrical, apex rounded and not blue with iodine, narrowed 
below into a long pedicel, 8-spored, wall thick ; spores obliquely 
l-seriate, continuous, wall thick, smooth, often guttulate, ellip- 
tical, ends narrowed, hyaliue (then brown, but this colour may 
be the result of poisoning), 42-45x 12-14 p; paraphyses 
numerous, cylindrical, septate, apices tbickened and brownish.

Exsicc. Fung. Cubenses Wrightiani, n. 654. 
Growing on branches and rotten wood. Cuba (Wright, 
nn. 383, 638, 646, 933); Ceylon (Thwaites); Madagascar 
(Baron). 
The spores are perfectly smooth, but often containing granular 
contents, in the Ceylon form described by Berkeley as Rhizina 
Thwaitesii. lam still of the opinion that the present species 
is much more nearly allied to Bulgaria than to Rhizina. 
RurgINA zonata, Berk. in Hook. Kew Journ. Bot. vol. vi. 
(1854) p. 6; Sace. Syll. viii.n. 186. (Pl. XVIII. fig. 10.) 
Orbicular when young, but often becoming irregular with age ; 
increasing in size by marginal growth, which appears to be arrested 
at times, thus producing concentric zones on the under surface ; 
rather fleshy; dise smooth, dark brown, externally uniformly 
densely but minutely velvety, 2-4 cm. across; hypothecium, 
excipulum, and cortex uniform in structure, and composed of 
brown, rather thick-walled, intricately interwoven hyphe, 5-7 pu 
thick, many of these hyphe become straight and run up amongst 
the paraphyses and asci; asci cylindrical, apex blunt, 8-spored ; 
spores obliquely l-seriate, continuous, smooth, elliptic-fusiform, 
ends acute, often 2-guttulate, slightly tinged brown at maturity,
