SPORORMIA 109 
Perithecia sunken and scattered, or more often aggregated 
into small clusters and erumpent by pushing up small areas of the 
substratum which fall away and leave the small clusters of peri- 
thecia exposed, subglobose with small black shining papilliform 
beak, 175-225 ۸ in diameter, coriaceous or often slightly brittle, 
always perfectly black and opaque when mature 
Asci 8-spored, clavate, broadly rounded above and contracted 
below into a short blunt usually curved base, 24-28 ۸ x 
170-200 رم‎ quite persistent, opening by a lid-like or a thimble- 
like rupture when the perforate membrane becomes plainly 
visible : paraphyses filiform, septate and constricted below, spar- 
ingly branched, longer than the asci and mixed with them 
Spores in 2-3 series and overlapping, 4-celled, deeply con- 
اج ا‎ cylindrical, straight or slightly curved, broadly rounded 
at the ends, 9-11 u. x 48-60 u; hyaline envelope surrounding the 
entire spore, swelling greatly in water where it shows striations con- 
tinuous with the septa of the spore. (PL st 19-27.) 
Distinctive characters: Globular perithecia, clavate asci and 
comparatively broad spores.
