SPHAEEOSPOBA. 293 



first, finally covered with a very small meshed network 

 formed by anastomosing, raised ribs ; paraphyses septate, 

 apex clavate and filled with brownish or red granules. 



Peziza trechispora, B. & Br., Ann. Nat. Hist., vol. xviii., 

 p. 77 (1846); Alycogr., fig. 129 (spore wrong; represented 

 as warted instead of being minutely reticulated.) 



Lachnea trechispora, Phil., Brit. Disc., p. 218, pi. vii., 

 fig. 41 (spores wrong ; should be reticulated.) 



On naked, damp earth, rarely on rotten wood.) 



Closely allied to S. asperior, but easily recognised by the 

 thick epispore being ornamented with a network of very 

 delicate ridges. Seen in optical section the thin ridges 

 resemble delicate, radiating spines in the thickness of the 

 wall ; hence, as in many other instances, the spore has been 

 erroneously described as echinulate. 



Type specimen examined ; also specimen in Cooke, Fung. 

 Brit., n. 288. S. asperior is confused with the present series 

 in the herbaria of Berkeley and Broome ; and may possibly 

 have been sent to correspondents as S. trechispora. 



Sphaerospora asperior. Sacc., Syll. viii. n. 764. 



Scattered, crimson to tawny red, sessile, closed at first, 

 soon becoming plane, rather fleshy, 25 mm. across ; externally 

 clothed with brown, septate, thick-walled, pointed hairs, 

 often more or less curved at the margin, and there measuring 

 250-350 x 8-10 /u, base often branching ; cortical cells large ; 

 asci large, cylindrical, tip obtuse, 8-spored: spores 1-seriate, 

 globose, hyaline, smooth at first, then bristling with crowded, 

 cylindrical, obtuse warts 2-3 //, long ; clavate, and containing 

 coloured granules when fresh. 



Peziza asperior, Nyl., Fez. Fenn., p. 21 ; Cooke, Mycogr 

 fig. 51 ; Phil., Brit. Disc., p. 85. 



On naked, damp soil. 



Specimens in Thum., Myc. Univ., n. 1211, and Eehm, 

 Ascom., n. 405 (called Humaria trechispora (B. & B.). 



Differs from S. trechispora in the distinctly warted, and 

 not reticulated spores. 



Sphaerospora binominata. Mass. 

 Scattered, sessile, subglobose and closed at first, then be- 

 coming almost or quite plane, rather fleshy, 1-2 mm. across ;
