 out into slender, free hj'phae of various lengths to form 

 the irregular margin ; asci large, cylindric-clavate, apex 

 slightly narrowed, pedicel short, stout, 8-spored ; spores 

 irregularly 2-seriate, cylindrio-oblong, ends rather obtuse,

 brown cells 8-10 /x diameter, and running out at the margin 

 into parallel, septate, paler hyphae ; asci cylindric-clavate, 

 apex narrowed, 8-spored, spores narrowly fusiform, ends 

 rather acute, becoming 3-septate, hyaline, smooth, irregu-
