clavate, yellowish, 30-40 x 6-8 /x; sterigmata 4, more or less 

 erect. Spores hyaline, white or slightly ochraceous in the 

 mass, subglobose, sharply warted, 5-6 (-8)ju, in diameter. 



Habitat. Amongst grass in woods, parks, lawns, etc. 

 Common. 



This is by far the most frequent of the yellow simple Clavarias, 

 being found in short grass in a variety of situations every 

 season. It may be distinguished at once from all other yellow 

 species by its subglobose, spiny spores. 



As pointed out in the notes in Trans. Brit. Myc. Soc. ii. 

 p. 163, C. dissipahilis Britz. is merely a synonym of C. inae- 

 qualis. The only justification for Britzelmayr's describing his 

 plant as a new species was Karsten's statement that the spores 

 of C. inaequalis were smooth and elliptical. This was an 

 error, as the examination of material in herbaria, including 

 Karsten's own specimens, clearly shows. It is possible that 

 a species with smooth elliptical spores occurs on the Continent, 

 but if so it is obviously very rare and cannot be regarded as 

 representing the old and well-known C. inaequalis. 



Dark forms of this species, almost orange in colour, sometimes 

 occur, and these represent the C. polymorpha rufa ( = C. rufa 

 Pers.) of the Flora Danica. (See Trans. Brit. Myc. Soc. iii. 

 P- 33-)

Plants small, unbranched, isolated or caespitose, straw- 

 coloured, becoming brownish with age; smell and taste not 

 marked. Clubs slender, 3-5 cm. high, 3-4 mm. thick, cylin- 

 drical or somewhat compressed, smooth, brittle, apex usually 

 acute. Stem usually very distinct, cinnamon-yellow. Flesh 

 somewhat darker than the hymenium. Internal structure 

 pseudoparenchymatous in transverse section. Basidia rather 

 large, 40-60 x 7-9 /x, contents granular, sterigmata 4. Spores 

 hyaline, smooth, globose, with a minute basal apiculus, 5-7 /(x 

 in diameter, contents granular. 



Habitat. In short grass. Rare. Specimens from Erring- 

 den, near Halifax (C. Crossland, 1905); Carlisle (Miss D. 

 Graham, 1908-1909); Chatsworth (A. D. C, 1909); Broseley, 

 Salop (G. Potts, 1909); Clare Island (A. D. C, 1910); Sands- 

 end, Yorks. (C. Crossland, 1912); Haslemere (E. M. W., 1913). 



C. straminea differs from C. argillacea in its smaller size, and 

 pointed cylindrical clubs, and also in its globose spores. In 

 both species the spore-bearing surface is paler in colour than
