NEW BRITISH LICHENS. 233 
On the decaying wood of an old holly near Lyndhurst in the New 
Forest. April, 1869. Very rare and local, and found only very 
sparingly on a single tree. Nylander observes that it is distinguished 
from Z. myriocarpa, De Cand., by the form of the paraphyses and the 
reaction with iodine, and from Z. adpressa, Hepp., by the paraphyses 
and the colour of the spores and hypothecium. 
3. L. deducta, Nyl. in litt.; thallus obscurely subgelatinous, but 
scarcely proper (as traces of a greenish effuse thallus are here and 
there visible) ; apothecia blackish, small, usually margined; spores 8 
in thece, colourless or faintly blackish, elliptical cr oblong, 3-septate, 
0010-13 mm. long, 0:0035—0:0045 mm. thick; paraphyses not 
discrete, thin layer of the apothecia reddish (hypothecium more 
obscure in the acea hymeneal gelatine blue, then wine-red with 
iodine. 
On decaying felled stumps of Holly in the New Forest, near to 
Brockenhurst. April, 1869. Very rare, and perhaps but a variety 
of L. subturgidula, Nyl., from which it differs chiefly by the apothecia 
being black and margined. 
4. L. spododes, Nyl. in litt. ; thallus greenish-yellow, thin, granu- 
lose, somewhat evanescent; apothecia cinereous or sordid pale, small, 
convex, immarginate; spores simple, oblong, 0°010-14 mm. long, 
0:0025—0-0040 mm. thick; hymeneal gelatine blue, and then wine- 
red with iodine. 
On old pales near Lyndhurst in the New Forest. April, 1869. 
Rare and local. It is closely allied to Z. denigrata, Frs., of which 
probably it is to be regarded as a subspecies, though externally it is 
readily distinguished from this 
5. Endocarpon Crombiei, Mudd, Brit. Clad. p. 36; parasitic on 
thallus of ZAamnolia vermicularis; apothecia PROF MR lateral 
minute, at length emersed, confluent, each verruca containing many 
nuclei; ostiola very minute, punctiform, depressed, pale reddish- 
brown; nucleus subgelatinous in yellowish-brown subceraceous tunic ; 
paraphyses slender, discrete ; spores 8 in thece, very minute, ellip- 
tical, unilocular, occasionally obscurely bilocular, hyaline. 
Apparently not very rare on the higher Grampians of Scotland, as 
Ben Lawers, Morrone, Ben-na-boord, on which last mountain it was 
first discovered by me in August, 1862. Though regarded by Mudd, 
l. c., as a trne lichen, Nylander considers it as a fungillus, and indeed -
