Mitrula lutescens, Massee (non Berk.). (PI. XIII, Fig. 77.) 
Scattered or fasciculate, entire fungus 3-7 cm. high; ascigerous 
portion 15-20 mm. long, 1-10 mm. broad, at first subcylindrical, then 
compressed, lanceolate, apex rarely rounded, yellowish olive or greyish 
ochraceous, solid, flesh pale ochraceous, sharply differentiated from 
the stem, which is similar in colour except at the base, which is greenish 
both inside and out, minutely squamulose, especially upwards. Asci 
inoperculate, subclavate, slightly narrowed towards the base, 130- 
I 5 °X 15-17 spores 8, irregularly 2-seriate, oblong-fusoid, straight 
or slightly curved, hyaline, 3-4-guttulate, 20-26x6-7 fx; paraphyses 
slender, irregularly branched from the base, tips clavate or subcapitate, 
3-4 11 thick, and often coated with mucilage.

This species agrees in many respects with M. viridis , but I consider 
it quite distinct by the colour being more ochraceous than green 
except at the base of the stem, by the ascigerous portion being 
relatively shorter, more lanceolate, broader in the middle, and more 
compressed, also by the stem being finely squamulose ; the spores are 
also a little larger and the asci a little smaller. It occurs on ground 
which is not pure clay. It is also neighbour to M. olivacea , but is 
well distinguished by its more ochraceous colour, general smaller size, 
stem longer than the ascigerous portion and greenish at the base, 
paraphyses usually not curved at the tips, and by the slightly larger 
and straighter spores. During drying, the present species becomes 
greener, whereas under the same conditions M. viridis becomes yellower 
(Boudier). 
Mitrula larieina, Massee. (PI. XIII, Fig. 69.) 
Gregarious, entire fungus 2-6 cm. high ; ascigerous portion variable 
in size and shape, clavate, subglobose, or ovate, sometimes more or 
less divided into two portions, often more or less compressed, especially 
when large, fragile, glabrous, becoming hollow, entirely adnate to the 
stem, but the lower margin sharp and distinct, usually slightly de- 
current down opposite sides of the stem, varying in colour from 
egg-yellow to deep orahge-red, \-i\ cm. high and broad; stem 
2-5 mm. thick, straight or wavy, smooth and with a silky sheen,
