Ascobolus crenulatus. Karst. Fung. Fenn. No. 763. 



Gregarious, sessile, at first spheroid, then flattened, nearly 

 plane, greenish-yellow, furfuraceous ; margin crenulate (1-5 

 m.m. broad) ; asci clavate ; sporidia elliptical, striate, violet 

 becoming brownish ; paraphyses slender. — Karst. Myc. Fenn. 

 \.p. 77. 



On grouse dung. Rannoch. Dr. Buchanan White. 



Sporidia •oi2- , oi6 x -oo6-'oo8 m.m. ; cups about 1-1 \ m.m. 

 broad ; disc of the Rannoch specimens, vinous when old, re- 

 taining the greenish colour at the base of the cups. 

 Ascobolus (Ascophanus) pilosus. Fr. 



Minute, sessile, yellow, testaceous, yellow or tawny-orange, 

 externally pilose with long hairs ; disc papillate ; margin 

 naked ; hairs simple, incrassated at the base ; asci clavate ; 

 sporidia hyaline, oblong ovate ; paraphyses slender, septate, 

 simple, or branched, granular. 



On grouse dung. Rannoch. Dr. Buchanan White. 



Cups /oth m.m. broad; sporidia "02 x -oi m.m. 



This is referred to A. pilosus as a variety, but the specimens 

 were more minute than usual, scarcely visible to the naked eye, 

 pallid. It differs from any form of A. papillatus and A. ciliatus 

 in the hairs not being marginal but clothing the surface of the 

 cup ; they are also more slender than in the other species. It 

 was accompanied by a minute Rypai'obius and Sphceria 

 (Sporormia) Notarisii. 



Xylaria Scotica. Cooke. 



Suberose ; stem very long, pallid, root-like, slender, 1-3 times 

 dichotomously branched above ; branches elongated, or very 

 short and fasciculate ; heads elongated, subcylindrical ; apex, 

 more or less acute, greyish-brown, then black ; perithecia very 

 numerous, slightly papillate ; asci cylindrical ; sporidia uniseri- 

 ate, elliptical, brown, minute. 



On the ground. Meikleour. Mr. D. Matheson. 



Entire length, including rooting base, 2 to 6 inches. Clubs 

 about 1 inch long ; sporidia 'oos-'ooG x -003 m. m. 



A most interesting addition to the British Flora. It was ex- 

 hibited at the Perth Fungus show, and is wholly unlike any de- 

 scribed species. The sporidia are smaller than in any other British 

 Xylaria. Commonly 6-8 heads arise from the rooting stem.
