COCCOPHACIDIUM. Eehm. (figs. 7-10, p. 01.) 



Ascophore globoso-depressed, at first buried in the sub- 

 stratum, then erumpent, splitting above in an irregularly 

 stellate manner, and remaining as an irregular border en- 

 circling the circular disc ; membranaceo-carbonaceous, black ; 

 asci clavate, apex broad with a central somewhat narrowed 

 prominence, 8-spored ; spores elongated and slender, clavately 

 fusiform, straight or slightly curved, hyaline, multi-septate, 

 arranged in a parallel fascicle in the ascus ; paraphyses slender, 

 septate, apex thickened and brownish.

 p. 89. 



Phacidium, of most aiithors. 



Distinguished by the form of the many-septate, colourless 

 spores, which are narrowly fusiform, but the widest part of 

 the spore is above its middle, hence there is a tendency to 

 become clavate, but both ends are pointed. 



Coccophacidium pini, Eehm, Krypt.-Flora, Disc., p. 

 98, figs. 1-5, p. 89. (figs. 7-10, p. 91.) 



Ascophores scattered or gregarious, erumpent, roundish, 

 hemispherical but depressed, at first closed and shining black, 

 then splitting into 4-6 obtuse teeth, and exposing the brown- 

 ish disc, l'5-3 mm. across; asci clavate, narrowed below 

 into a long, slender pedicel, 8-spored ; spores arranged in a 

 parallel fascicle, elongated, curved, narrowly fusiform, both 

 ends pointed, the lower half of the spore narrower than the 

 upper half, at first continuous, then with many large gut-
