86 FUNGUS-FLOKA. 



the fungus parallel to that of the leaf on which it is growing ; 

 covered at first, then exposed by the longitudinal splitting of 

 the epidermis ; excipulum composed of parallel, thin, smoky- 

 olive hyphae, and forming a narrow, 2-lipped border, disc 

 waxy, buff then brownish, 1 mm. or more long; asci cylin- 

 dric-clavate, apex conspicuously narrowed, 8-spored; spores 

 irregularly 2-seriate, hyaline, narrowly elliptic-oblong, ends 

 obtuse, straight or slightly curved, at first continuous and 

 4-guttulate, then 3-septate, 16-26 X 4-5 p; paraphyses 

 numerous, hyaline, 2 5-3 p. thick, very slightly thickened at 

 the apex, and passing gradually into the hyphae of the 

 excipulum.

 thickish, indistinctly marginate, pale-coloured, excipulum 

 rudimentary ; asci clavate, 8-spored ; spores elongated,
