OCELLAEIA. 83 



Propolis lecanora, De Not., Propost. Ketif. Discom., p. 10 ; 

 Phil., Brit. Disc., p. 374. 



On- dry branches of various species of willow and poplar. 



There appears to be some uncertainty about the secondary 

 form of fruit of the present species ; possibly there may be 

 two forms, or again, the bodies supposed. to be pycnidia may 

 be parasitic. 



According to Tulasne the pycnidia are elongated, colour- 

 less, 2-4-celled, 30-50 X l-l| /. 



Phillips gives the following : Pycnidia intermixed with 

 the above, occupying the sides or summit of the same stroma, 

 disc-shaped ; stylospores oblong or oblong-elliptic, straight 

 or slightly curved, issuing through the narrowly perforated 

 epidermis ; sterigmata branched, rather stout. 



Ocellaria succinea. Mass. (n. ep.) 



Erumpent, usually in groups of three or four, somewhat 

 turbinate, disc plane or very slightly convex, surrounded by 

 a delicate, entire margin which is at first connate with the 

 spurious bark margin, eventually becoming free ; entirely 

 pale amber-colour and almost translucent when moist, 

 ^ j mm. across ; excipulum parenchymatous, cells 68 p. 

 diam. ; asci clavate, apex narrowed, pedicel long ai.d slender, 

 8-spored ; spores irregularly 2-seriate, smooth, hyaline, nar- 

 rowly elliptical, 1416 x 6 ft; paraphyses numerous, fili- 

 form, apex not thickened, 1*5 /* thick, agglutinated together 

 with hyaline mucus. 



On beech bark. 



Distinguished from all other species by the small elliptical 

 spores and pale amber colour. 



Ocellaria pyri. Mass. 



Gregarious and usually in confluent groups of 2-3, erum- 

 pent, orbicular, fleshy, black with a purple tinge ; disc plane 

 or concave, margin irregular, up to 1 mm. across ; excipulum 

 composed of parallel, smoky-brown hyphae; asci clavate, 

 apex rounded, base elongated and narrowed, 8-spored ; spores 

 uniseriate or sometimes 2-seriate at the apex, continuous, 

 sometimes 1-2-guttulate, hyaline, elliptical, smooth, 15-22 X 

 7-9 p, with a narrow hyaline border ; paraphyses very nume- 

 rous, slender, rather wavy, sometimes branched, a little
