SEPEDONIUM ASTEROPHORA. , 325 



Ocularia elliptica, Berk., Gard. Chron., 1881, with fig., 

 Giev., 1881, p. 51 ; Sacc., Syll., iv. n. 752. 

 On several cultivated varieties of Lilium. 



SEPEDONIUM. Link. (fig. 25, p. 313.) 



Hyphae vaguely branched, creeping; conidia produced at 

 the tips of branches, solitary or 2-3 together, one-celled, 

 minutely warted, hyaline or brightly coloured. 



Sepedonium, Link, Obs. Myc., i. p. 16 ; Sacc., Syll., iv. p. 140. 



Most species are parasitic on fungi, and are the conidiul 

 stage of species of Hypomyces. 



Sepedonium chrysosperamm. Fr. (fig. 25, p. 313.) 



Hyphae effused, interwoven, rather thick, almost hyaline, 

 variously forked and branched, bearing short, spreading, 

 lateral conidiophores ; conidia solitary, globose, minutely 

 warted, very numerous, bright yellow, 13-17 /A diameter. 



Sepedonium cJtrysospermum, Fr., Svst. Myc., iii. p. 438 ; Sacc., 

 Svll., n. 754. 



Very common on decaying fungi, Boletus, Agarics, &c. 

 Probably a true parasite, attacking the fungus early and 

 arresting its development. At first white, then bright yellow 

 and powdery from the very numerous spores. 



The conidial condition of Hypomyces chrysospermus. 



Sepedonium Tulasneanum. Sacc. 



Effused, ochraceous or with an olive tinge, hyphae 

 sparingly septate, dividing into 2-3 subequal, short branches 

 near the apex, each producing at its summit an ochraceous, 

 elliptic-fusiform, warted con id mm, 16-24 X 8-10 ft. 



Sepedonium Tulasneanum, Sacc., Syll., vol. iv. n. 766. 



Parasitic on various species of Boletus. 



The conidial condition of Hypomyces Tulasneanus. 



ASTEROPHOEA. Ditrn. (fig. 5, p. 358.) 



Hyphae vaguely branched, creeping; conidia stellatcly 

 tuberculose.
