BERKELEY'S TYPES OF FUNGI. 485 
thecium, excipulum, and cortex formed of hyaline, irregularly 
polygonal cells, which gradually become larger towards the 
cortex; asci narrowly cylindrical, apex obtuse, about 250 x 10 p; 
spores 8, 1-seriate, hyaline, continuous, smooth, elliptic-oblong, 
ends obtuse, often 1-2-guttulate, 19-22 x 7-8 u; paraphyses very 
slender, expanding into a pyriform or clavate tip, 5-6 p thick. 
Humaria Muelleri, Sacc. Syll. viii. n. 455. 
On the ground. Plenty Creek, Australia (Mueller, n. 9) ; 
Melbourne (F. Reader, n. 23). 
Threads of the mycelium abundant, binding the particles of 
sand, very variable in thickness (Berkeley). 
Pzziza (§ HUMARIA) SCATIGENA, Berk. & Curt. in Journ. Linn. 
Soc. ( Bot.) vol. x. (1867) p. 366; Cooke, Mycogr. fig. 72. 
Gregarious ; closed at first, then gradually expanding, but the 
margin more or less persistently incurved, rather fleshy, sessile, 
3-6 mm. broad ; disc blackish-purple with a tinge of green when 
fresh, smooth and even, externally pallid or whitish, minutely 
pulverulent or granular; substance parenchymatous ; asci cylin- 
drical, apex somewhat truncate; spores 8, at first obliquely 
l-seriate, becoming irregularly 2-seriate, and the ascus clavate 
just before dehiscence, smooth, continuous, hyaline (in all the 
specimens examined the spores are now pale brown, but whether 
this is normal or due to age or preservatives cannot be deter- 
mined), wall thick, broadly elliptical, 23-27 x 11-13 p; para- 
physes slender, tips thickened. 
Humaria scatigena, Saec. Syll. viii. n. 588. 
Ezsicc. Fungi Cubenses Wrightiani, n. 667. 
On dung. Cuba (Wright, n. 636). 
The immature asci become blue throughout their length with 
a solution of iodine, whereas the mature asci are not coloured at 
all by the same treatment. 
Peziza (Š HUMARIA) SPISSA, Berk. in Grevillea, vol. iv. (1875) 
p. 152 ; Cooke, Mycogr. fig. 79. 
Ascophore closed at first, then gradually expanding until plane, 
or sometimes slightly convex and the margin drooping, rather 
fleshy, often more or less lobed or incised at the margin, but some- 
times also quite entire; disc even, bay-brown, externally paler 
and minutely scurfy or granular, narrowed into a very short, 
stout, whitish, stem-like base, 1-2 cm. across ; substance entirely
