166 FUNGUS-FLORA. 



margin minutely crenulate, externally scurfy, entirely 

 blackish-brown, 24 mm. diameter ; excipulum parenchyma- 

 tous, cortical cells, 2030 p. diameter, brown ; asci clavate, 

 tapering into a long, slender, often curved pedicel, 8-spored ; 

 spores irregularly 2-seriate, broadly elliptical, ends obtuse, 

 hyaline, then violet, at length brown, epispore smooth at 

 first, then becoming broken up into fragments surrounded 

 by hyaline fissures, giving the spore the appearance of being 

 finely verrucose, 20-22 x 12-14 p.; paraphyses slender, 

 septate, not much thickened at the tip, slightly longer 

 than the asci.

Ascophore up to 1 mm. diameter, gregarious or crowded, 

 hemispherical at first, then almost or quite plane ; excipulum 

 parenchyrnatous ; cells irregularly polygonal, large; disc 

 varying from deep orange-red to bright crimson ; externally 

 yellowish, pilose, hairs brown, thick- walled, septate, conical, 

 pointed, smooth, 80-L30 x 10-12 p., largest and most abun- 

 dant near the margin; asci cylindrical, apex rounded, nar- 

 rowed at the base to a slender pedicel, 8-spored ; spores 

 obliquely 1-seriate, elliptical, ends obtuse, smooth and hyaline 

 for a long time, then the epispore becomes violet and finally 

 violet-brown, and marked with delicate anastomosing lines. 

 16-18 x 9 p.; paraphyses straight, septate, the upper half 

 gradually increasing in thickness, tips about 5 p. broad, 

 orange. 



A remarkable species, intermediate between Ascobolus and 

 Lachnca, agreeing with the former in having the epispore 

 violet, then brownish, and minutely more or less longitu- 

 dinally rugulose at maturity, the asci, however, so far as I
