On dead stems of Umbellifere. 
Cups very minute, generally sessile, but sometimes 
subsessile; nearly the same colour throughout, and so 
nearly the shade of the dead stem on which they grow 
as to be hardly distinguishable. The dry specimens 
show no hairs, but are fimbriate on the margin, owing to 
the unequal length of the hair-like cells which adhere 
together. 
Name—After Dr. Greville. 
Near Edinburgh! (Dr. Greville). Near Berwick, on 
the cow-parsnip (Johnst., “Flo. Berw.,” J. ¢.). 
16. Mollisia atrata. (Pers.)

dicularly rugose; margin whitish; hymenium at first 
whitish, becoming cinereous; asci fusiform-clavate or 
cylindraceo-clavate; sporidia 8, fusiform, 8—10 x ly;

On dead herbaceous stems. Autumn. 
It is to my mind very doubtful whether the plant 
generally accepted by authors, and described above, is the 
true plant of Persoon. That his plant grew on trunks 
he distinctly states, while most authors of to-day accept 
one or other: of several closely allied plants that grow on 
herbaceous stems and leaves. It would only tend to con- 
fusion, however, to disturb this state of things; we have, 
therefore, followed Dr. Karsten’s view of the species,
