125 MESSRS. J. A. WHELDON AND W. G. TRAVIS ON 
incolor vel ubi excipulo nigricanti contiguum vestigio flavi coloris 
tinetum ; epithecium et sepe etiam hymenium solida, pallide fuliginosa, 
in plagas tenues dissecta fere incoloria. Spori 25-38 x 1:2-25 ш, septis 
valde obscuris plerumque 7, raro recti, sepe curvi et haud infrequenter 
sigmoidei, implexi in asco. 
Hab. Incrusting decaying mosses on the sand-dunes at Freshfield, 
April 1914. Туре spec. in herb. Travis. 
Differs from the type in the shorter, more strongly curved spores, and the habitat. 
The var. hypnea, А. Г. Sm., grows on moss on rocks, and has spores still longer 
than in the type. 
BACIDIA SALICICOLA nobis, spec. nov. 
Thallus parcus vel evanescens.  Apothecia e rubello ad nigrum 
variantia subminuta, mox immarginata. Lypotheeium incolor ; epithe- 
cium brunneum. Spori 29-35 x 2-375 м, uno polo sepe attenuati, nunc 
eylindrici, nunc fusiformes, plerumque ineurvi. Gelatina hymenii iodo 
cærulea, deinde tarde in vinosum abiens. 
Differs essentially from B. arceutina, Branth & Rostr., in its shorter, stouter spores, 
aud smaller apothecia ; approaches in these characters to B. Becknausti, Koerb., but 
differs from that in the spores being often acute at one or both ends, in the brighter 
coloured apothecia, and colour of the epithecium. 
Hab, Ou dead twigs and exposed underground stems of бай repens 
on the coastal sandhills. First: collected at Formby, April 14, 1913. 
since seen at Ainsdale and Freshfield, and is probably not uncommon 
all over the dune tract. It has also subsequently been collected once оп 
pine-bark near Ainsdale. 
ВАСИЛА EPIPHYLLA nobis, spec. nov. 
thallus fere evanescens, в granulis paucis virescentibus exsiccando 
cinereis consistens. Apothecia admodum minuta, nigra, sessilia, plana, 
deinde convexa, mox immarginata, intus incoloria.  Æpithecium pallide 
fuscum.  Puraphyses clavate, plerumque apice incolores, levissime 
cohærentes. — Zypothecium pallide flavido-fuscum. Нутешит per- 
pallidum, iodo viridi-cceruleum, mox saturate vinosum. Asci tenues, 
47 р longi. Spori tenuiter aciculares, uno polo заре curvi, multiseptati, 
33-45 x 1-2 д. 
This very minute and inconspicuous species is distinguished from allied species by 
its very minute apothecia, less conglutinate paraphyses, and habitat on dead leaves, 
Its nearest relation from which it may be derived is В. arceutina, Branth & Rostr., 
from which it is easily separated by its smaller apothecia without red tinge, shorter 
spores, and peculiar habitat. В. Beckhausii has shorter spores and different paraphyses, 
more coloured and conglutinate. 
Hab. On fallen leaves of Salix repens on the sand-dunes near Ainsdale, 
Dec. 1913.
