PATELLAKIA. 101 



applanate, i— | mm. across, disc plane, blackisli-brown, the 

 slightly upraised margin with a reddish-hrown. or viaous 

 tinge ; asci cylindric-clavate, narrow and elongated, 8-spored ; 

 spores irregularly biseriate, narrowly cylindric-fusiform, 

 straight or slightly curved, hyaline with a tinge of green, 

 3-septate, 17-20 x 4 /x ; paraphyses slender, about 1-5 /j, 

 thick, hyaline, sometimes branched. 



Purella atro-vinosa, Sacc, Syll., viii. n. 3259. 



On bark. 



Type specimen examined. 



The disc is sometimes dark brown, margia lighter brown, 

 with or without a vinous tinge. The spores may perhaps 

 become 5-septate at maturity. 



Patellaria maura. Phil., Brit. Disc, p. 368. 



Ascophores sessile, scattered, at first globose, becoming 

 patellate, fuliginous-black ; margin raised, crenulate or torn, 

 about 1 mm. across ; asci cylindric-clavate, attenuated to a 

 narrow base, 8-spored ; spores narrowly elongate-fusiform or 

 subcylindrical, straight or curved, 30-38 x 5-6 fn; para- 

 physes filiform, tips hooked or curled.

On dead wood. 



From the figure given in " Grevillea " we learn that the 

 spores are irregularly biseriate and multi-guttulate ; also that 

 the cortex of the excipulum is parenchymatous. The spores 

 are presumably colourless, although we are not told so, and 

 may possibly become septate, otherwise the species cannot be 

 included in Patellaria.

Sessile, gregarious, orbicular, plane or very slightly 

 convex ; black, disc often a tinge of olive or brown when 

 moist, up to 1^ mm. across ; excipulum consisting of in- 

 distinct, more or less parallel, dingy olive hyphae ; asci 

 clavate, apex rounded, attenuated into a slender pedicel,
