CRYPTOGAMI A. ALGiE. Lichen.

L. niva'lis. Saucers pale flesh-colour, terminating; foliage white, 
ascending, jagged, curled, pitted, smooth: the edges raised. 
( E . Bot. 1994. E.)— FI. Dan. 227— FI. Lapp. 11. 1 —Dill. 21. 56. 
Rarely found in fruit. Linnaeus describes the saucers as mentioned above, 
but they are not expressed in his figure, nor in that of the FI. Danica. 
Dillenius examined great quantities of this Lichen, and found only minute 
dots like tubercles on extreme edges of the segments, of a light reddish 
colour. These may be the rudiments of the saucers mentioned by 
Linnaeus.

L. ampulla 'ceus. Saucers dark purple within, globular, inflated: 
foliage rather flat, lobed, scolloped. 
Dill. 24. 82— Jacq. Coll. 1. 4. 3. c — Hoffm. Lich. 13. 2. 
Segments, broad, short, finely scolloped, smooth on both sides, brownish, or 
purplish black. Saucers at the base, or at the edge of the leaves, very 
large, not hairy, like an inflated bladder perforated at the top, wrinkled, 
greyish, within dark purple. Dill. 
This very singular plant does not seem to have been found since the time of 
Dillenius. The only known specimen was in his herbarium at Oxford, 
but by something like slight of hand, it was transported to Germany, 
where it was purchased by Professor Jacquin, and in whose possession it 
was seen by the late Dr. Sibthorpe, to whom it was restored by the Pro¬ 
fessor, so that it may now be seen again in the herbarium. It was drawn 
under Jacquin’s direction, and this drawing has been copied by Hoffman.

L. tenuis'simus. Saucers dirty red, sunk in the leaf, border broad, 
foliage brownish green, tiled, finger-like, with many clefts. 
(E. Bot. 1427. E.)— Dicks. 2.8. 
Minute and elegant. Leaves minute, brown when dry, of a tender mem¬ 
branaceous jelly-like substance, with many clefts at the ends; segments 
strap-shaped, unequal, expanding, somewhat fringed. Saucers pro¬ 
portionally large, with imperfect borders, the younger hollow> pitcher¬ 
shaped, on the surface of the leaves and of the same colour, the older 
flat, sometimes convex, of a dirty red. Dicks. 
(Fine-cut Gelatinous Lichen. Parmelia tenuissima. Achar. E.) On 
sand-banks, near Norwich. On dry sand-banks usually amongst moss.

L. membrana'ceus. Saucers pale yellow; foliage brimstone colour, 
mealy, plaited and wrinkled, depressed.
