On dead wood. 



Specimen in Phil., Elv. Brit., n. 130, examined. 



Scarcely worthy of being considered a true variety, transi- 

 tions as to colour being not unknown. Eehm says the spores 

 are clavate-elliptic. 



Orbilia Leightoni. Sacc, Syll , viii. n. 2600. 



Scattered, minute, sessile, hemispherical, then slightly 

 concave ; margin incurved ; exterior glabrous, very pale 

 yellow; hymeuium same colour; asci clavate ; spores 8, 

 oblong-elliptic, 8 X 3 /x; paraphyses slenderly filiform.

On Polyporus. 



Cups |-1 line broad. The colour varies from white to 

 very pale yellow ; sometimes diaphanous. The spores are 

 considerably larger than Peziza epipora, Nyl. (Phil.) 



Unknown to me. 



Orbilia auricolor. Sacc, Syll., viii. n. 2575. (figs. 

 45-47, p. 156.) 



Gregarious or sometimes confluent, sessile, subgelatiuous, 

 closed at first and almost globose, then becoming plane with 

 a blunt, glabrous, upraised margin, surrounded by a delicate 

 web of hyaline, septate, branched hyphae, which spring from 

 the basal cortical cells, clear orange, |— li mm. across ; dingy 

 orange, but almost unchanged in form when dry; hypothecium 

 and excipulum truly parenchymatous, cells large, cortical 

 cells irregular in form and size, up to 20 /x across, becomin"- 

 smaller towards the entire margin ; asci narrowly clavate, 

 8-spored; spores obliquely 1-seriate, hyaline, continuous, 

 straight,_ 5-6 x 1"5 jx; paraphyses numerous, cylindrical, 

 2-6 /x thick, slightly flattened and broadened like the head 

 of a nail at the extreme tip.
