336 Mas see and Salmon. — Researches on 
cylindrical, shortly stalked, 45-60 x8-io/z, 8-spored: spores uniseriate, 
ovoid, 4*5-8 X 3-4 /*• 
Hab. — On Rabbit-dung, Royal Gardens, Kew, England, Oct. 1900 ; 
on Hare-dung, Kew, Mar. 1901. (Distrib. — N. Italy; on Cow-dung.) 
-S’, minima has hitherto been known from only a single locality in 
Italy. The species is at once recognized by the small size of all its 
parts, and being almost invisible under a simple lens, is probably 
often passed over. Saccardo and Spegazzini give the size of the 
spores as 8 x 4 m, but in our specimens one perithecium contained 
asci with spores measuring only 4*5 X 3 /* ; in other instances, however, 
the spores measured 6-7 x 3*5-4 The wall of the perithecium is 
so translucent that the asci and coloured spores can be seen within 
the closed perithecium. 
S. hirta, Hans. (Fig. 7). 
-S', hirta , Hans., in Vidensk. Meddeh, 1876, p. 336, PI. VII, ff. 
17-24 (1876-77); Sacc. Syll. Fung, i, 232 (1882). 
Perithecia rather large, i-ijmm. high, basal part subglobose, 
olivaceous, narrowed upwards into a rather long, blackish, conical 
neck, which is more or less covered with dark brown or nearly black 
septate rigid simple hairs ; asci long-stalked, clavate-fusoid ; spores 8 
(rarely 4), ovoid, 40-46x20-22^, furnished at both ends with a 
hyaline appendage about equalling the spore in length. 
Hab. — On Cow-dung, Kew, England, Nov. 1900. (Distrib. — Den- 
mark, on Cow-dung.) 
Hansen (1. c.) remarks that the size of the spores is extremely 
variable in the present species, and records cases of spores varying 
between the wide limits of 24-58 x 13-5-25 ^ .

Perithecia scattered or subgregarious, mm. high, greenish 
black, often surrounded at the base with spreading pallid hyphae, 
subimmersed or wholly superficial, subglobose with a short or rather 
long bluntly conical blackish neck, which is sometimes slightly curved, 
neck and sometimes the upper part of perithecium more or less 
covered with long stiff greyish acute mostly aseptate bristles, usually
