Gregarious, or often in clusters of 2-4 plants, entire fungus 1-2 cm. 
high; ascigerous portion fleshy, undulate or almost plane, margin 
thick, incurved, glabrous, blackish-green, 4-8 mm. broad ; stem 
i-i *5 cm * long* about 3 mm. thick, more or less distinctly squamu- 
lose, equal or thickened upwards, coloured like the fertile portion, or 
paler ; flesh pale greenish-yellow. Asci clavate, apex narrowed, pore 
not blue with iodine, 1 30-1 50 x 1 1-12 p; spores 8, irregularly 2-seriate 
above, 1 -seriate below, hyaline, smooth, narrowly elliptical, ends 
obtuse, usually straight, 18-22 x 5-6 /*, 3-5-guttulate ; paraphyses 
slender, septate, often branched, tips scarcely thickened, greenish.

Had. — On the ground in woods, in damp places. 
Distr. — Germany, France (Montmorency, Boudier ). 
Requires to be carefully distinguished from dwarf forms of Leotia 
ludrica , Pers. The chief distinctions are, the absence of the piriform 
tips of the paraphyses, so characteristic of all forms of Z. ludrica ; 
the somewhat smaller asci, and the more distinctly squamulose stem. 
There is a specimen in the Kew Herbarium labelled * Leotia 
atrovirens, W. G. Farlow, Mass., U.S.A., n. 4/ This specimen is in 
reality Z. ludrica , f. chlorocephala , as defined in the present work ; 
therefore if the evidence of Z. atrovirens occurring in the United States 
happens to depend on this specimen, it should be cancelled.
