108 FUNGI. 



mushroom with the cup turned inside out, the asci 

 lining its interior. 



Peziza cocciriea is not uncommon in woods. It is 

 whitish outside, the interior of the cup being of a 

 brilliant scarlet colour. It is from half an inch to an 

 inch in height. 



Peziza stercor'ea (PI. VIII. fig. 7) is often found 

 upon dung. The surface of the cup of this Fungus is 

 granular and covered with bristles (figs. 8 & 11). The 

 cup is concave (fig. 10), and lined with the asci (fig. 9), 

 among which are simple paraphyses. 



The Pezizce are excellent Ascomycetous Fungi for 

 exhibiting the asci, as they are more or less soft, and 

 thus sections of them may be easily prepared, or they 

 may readily be picked to pieces with the mounted 

 needles. 



TTTBERACEI. In this family is contained the Truffle 

 (Tuber cibdrium). The asci are situated upon the 

 inner surfaces of the winding canals traversing the 

 substance of the fleshy fruit (peridium) of which the 

 truffle consists. 



PHACIDIA'CET. To this family belongs Hysterium 

 frax'ini (PL VIII. fig. 30), which is found upon ash- 

 twigs. The drawn-out capsules or perithecia (fig. 31) 

 are black and elliptical, with a longitudinal fissure or 

 orifice, and contain the asci (fig. 32) with the spores. 



SpH^RilcEi. Dothid'ea typhina (PL VIII. fig. 12) 

 is a common Fungus upon the stems of living grasses. 

 It forms an orange-coloured patch or layer encircling 

 the stem, and covered with little dots. On making 

 a section (fig. 14), it appears composed of a row of 

 oblong or obovate closely placed capsules (perithecia) 

 immersed in and continuous with a finely fibrous re- 

 ceptacular mass (stroma). The asci (fig. 15) are very 

 slender, arising in a tuft from the bottom of the cap- 

 sules, and containing eight still more slender spores. 

 Except under a very high power, the spores appear 

 as interrupted lines running down the interior of the
