BERKELEY'S TYPES OF FUNGI. 487 
excipulum, passing into a pseudo-parenchymatous tissue in the 
cortex, where groups of cells run out to form the external warts 
or granulations ; asci cylindrical, narrowed into a slender, often 
crooked pedicel, apex rounded, wall thickened, not blue with 
iodine, about 200 x 15 p; spores usually four in an ascus, some- 
times fewer, never more, hyaline, continuous, broadly elliptical, 
for a long time smooth, finally very minutely and delicately 
rugulose, sometimes 1—2-guttulate, size rather variable, averaging 
22x12,; paraphyses numerous, slender, only very slightly 
thickened at the tips.

On rotten wood. Cuba (Wright, n. 650). 
Sometimes two or three spores only are present in an ascus; I 
have never seen more than four. The epispore is certainly very 
minutely, but distinctly, rugulose when quite mature. 
Peziza (Š HUMARIA) ustoruM, Berk. $ Broome in Journ. 
Linn. Soc. ( Bot.) vol. xiv. (1875) p. 105 ; Cooke, Mycogr. fig. 61. 
Gregarious, or sometimes crowded ; globose at first, the dise 
gradually expanding until only slightly concave, rather fleshy ; 
1-2 mm. high and broad; disc crimson, externally brown, rugu- 
lose, the obtuse margin and for some distance down the outside 
glabrous; the lower cortical cells giving origin to numerous 
hyaline septate hyphe, 6-8 p thick, which fix the fungus to the 
substratum; hypothecium and excipulum parenchymatous, tlie 
component cells gradually becoming larger towards the cortex, 
where they measure from 40-60 y diameter, irregularly polygonal, 
hyaline ; asci narrowly cylindrical, narrowed below into a slender 
pedicel, apex rounded, not blue with iodine, 300 x 14 4; spores 5, 
obliquely or almost vertically l-seriate, continuous, hyaline, 
smooth, broadly elliptical, ends obtuse, often 1-2-guttulate, 
22-25 x 10-121; paraphyses slender, septate, apex suddenly 
thickened and cylindrical, exactly resembling a reed-mace. 
Humaria ustorum, Sace. Syll. viii. n. 453. 
On burnt earth. Habgalla, Ceylon (Thwaites, n. 279). 
À fine and very distinct species, readily recognized by the 
peculiar paraphyses, which exactly resemble a reed-mace in 
miniature. 
A. fungus found growing on burnt earth near Berlin was at one 
time supposed by Rehm to be the same as P. ustorum, and was
