 9-10 X 1-^ /x, hyalinis, coacervatis hyalino-succineis. (Tab. 516,

 latere ad septa conidia gignunt.

Ascophoris f-1 mm. diam., gregariis, sessilibus, hemisphaericis, 

 coccineis ; margine elevate, piloso. Pilis brunneis, 300-450 x 

 12-20 fx, crasse tunicatis, superne attenuatis, rigidis, erectis, 

 septatis. Ascis cylindraceis, 200 x 20 [x, apice truncatis, basi 

 subattenuatis ; sporidiis oblique monostichis, ellipticis, levibus, 

 hyalinis, continuis, utrinque obtusis, eguttulatis, 22-25 x 11-12 /x; 

 paraphysibus superne subincrassatis, granulis rubris repletis. 



On rabbits' dung, Sutton Park, May. At first sight closely 

 resembling Ascophamcs pilosus. Outer cells of cortex very large, 

 hyaline, 40-50 /x diam. Marginal hairs in two or three rows, very 

 similar to those of L. stercorea, but without the stellate hairs of 

 that species, though mixed below with shorter subhyaline hairs, 

 as in L. cop'inaria, which, however, is -|-1 cm. across. Possibly 

 this variety owes its smaller dimensions to its habitat. 



179. Chsetomium chlorinum m. Ch. Fieberi var. chlorina 

 Sacc. Mich. i. 27 ; Syll. Fung. i. 223. 



Perithecia black, gregarious, subovate, arranged more or less 

 in rows, completely hidden by a mass of very long pili, which are 

 simple (rarely branched), septate, roughish, slender and flexuous, 

 at first yellowish, then yellowish green, at length olive-brownish 

 and (under the microscope) fuscous, paler upwards, 4 [x diam. 

 Asci clavate, longly stipitate, soon diffluent ; sporidia eight, 

 distichous and at last conglobate at summit of ascus, at first 

 colourless, then greenish yellow, at length smoky-olive, lemon- 

 shaped, uniguttulate, and slightly unequal-sided, 15 x 10 /x when 

 mature. Paraphyses numerous, very delicate, filiform, longer 

 than the asci. Asci 50-55 x 16-20 (part, sporif.), stipes 40-50 fx 

 long ; paraphyses 2^3 fx diam. and about 100-130 fx long. 



On rotting stems of Jerusalem Artichoke and similar stems, 

 Sutton Coldfield (Wk.) and Hunnington (Ws.), June, September. 

 Ch. olivaceum C. et E. (Grevill. vi. 96) seems to be closely allied, 

 but the sporidia are described as "brunneis." 



Ch. chlorinum appears at first as a small tuft of hairs which 

 are seated on a black tubercle ; the hairs are blackish at the base, 

 then greenish, at the summit yellow. In this stage they are 

 nearly straight, but later, as the perithecium develops, they 

 become very long and intricately flexuous. Their roughness is 

 due to minute crystals which are easily removed by water.
