PATELLAEIA. 107 



composed of very long, narrow, olive-brown cells radially 

 arranged ; paraphyses narrowly cylindrical, 8-spored ; spores 

 irregularly 2-seriate, narrowly elliptical, ends rather pointed, 

 becoming 3-septate, hyaline, 12-18 X 4-5 /a; paraphyses 

 slender, about li /i thick, hyaline, suddenly becoming pear- 

 shaped and brown at the apex; hypothecium colourless.

Durella lecideola, Sacc, SyU., viii. n. 3246. 



On dead wood of poplar and birch. 



Specimen examined from Klotzsch, Herb. Myc, ed. nov. 

 Eabenh., n. 217. 



The present species is almost intermediate between Durella 

 and Patellaria ; agreeing with the former in the thin, colour- 

 less hypothecium ; with the latter in the firm excipulum not 

 being truly parenchymatous. 



Patellaria hyperici. Phil., Grevillea, x. p. 69 ; Brit. 

 Disc, p. 363. 



Gregarious or sometimes confluent and irregular in out- 

 line, very minute, sessile and sinuate at fijst, then somewhat 

 superficial, discoid, verj' thin, immarginate when moist, 

 somewhat concave and marginate when dry, glabrous, black- 

 ish-brown, up to ^ mm. across ; excipulum minutely paren- 

 chymatous ; asci clavate, narrowed below into a slender 

 pedicel, 8-spored; spores elliptic-oblong, ends obtuse, hya- 

 line, 3-septate, straight or very slightly curved, 17—20 X 

 5—7fj.; irregularly 2-seriate ; paraphyses numerous, filiform, 

 about 2 /x thick, hyaline, apex very slightly or not at all 

 thickened 



Lecanidion hyperici, Sacc, SrU., viii. n. 3288. 



On dead stems of Sypericum. 



Specimen in Phil., Elv. Brit., n. 191, examined. 



Cups 100 to 300 fji broad, at first sinuate, then emerging. 

 The sporidia of this species germinate freely within the 

 ascus, thrusting the germ-tubes through the walls of the 

 ascus ; the free sporidia often present a germ-tube twice their 

 length while yet in the hymenium. (Phil.) 



[J< will he observed that the species, unfortunately, have not been 

 arranged under the two sections depending on tJie number of 

 septa/]
