and Asplenium Ruta-muraria are abundant on the great 
outcrops of Magnesian Limestone. 
In the centre of the village green at Scriven is a fine ex- 
ample of the Evergreen Oak, and within the park the Beech 
Avenue is a prominent feature. The lake yielded Myriophyllum 
verticillatum and Polygonum amphibium. In the woods was 
an abundance of Wild Cherry and Blackthorn, made extremely 
effective by reason of the profusion of bloom which they bore. 
The woods on each side of the River Nidd would doubtless 
give greater results later in the year. There are some fine 
coniferous belts of Larch, Spruce Fir, and Scots Pine, the 
remaining trees being chiefly Oak, Ash, and Mountain Elm. 
Anemone nemorosa and Ranunculus Ficaria provided the flower 
carpet, though Primula vulgaris, Cochlearia officinalis, Lychnis 
diurna, and Nepela Glechoma displayed a fair amount of 
blossoms. Stellaria nemorum, Circcea lutetiana, and Veronica 
hedercefolia were also noted. Brachypodium sylvaticum is a 
common grass. Many plants of Aconitum Napellus, Ribes 
nigrum, and T anacetum vulgar e occur along the banks of the 
Nidd, but these are doubtless garden escapes. The parasitic 
Lathrcea squamaria was in great abundance, the tree root- 
lets preyed upon being those of Holly, Alder, Beech, Sycamore, 
Mountain Elm, Larch, and Spruce Fir. 
Fungi. — Miss C. A. Cooper writes :• — 
The area investigated included the woods on the Scriven 
Estate, and also the woods on the right bank of the River 
Nidd as far as the railway bridge. On the whole the ground was 
barren, perhaps partly owing to the dry weather, but more to 
the early season. The following is a list of the species noted : — 
Panceolus campanulatus, P. phalenarum, Collybia velutipes, 
C. tenacella, Pluteus cervinus, Agaricus campestris (quite good 
specimens), Hypholoma Candolleanus, H. fasciculare, Psathyra 
mastiger, Tubaria furfuracea, Fomes igniarius, Polystictus 
versicolor, Stereum hirsutum, Hirneola auricula-judce, Lyco- 
perdon pyri forme (in one case an exceptionally large mass, all 
last year’s), Peziza reticulata, P. vesiculosa, Mollisia cinerea, 
Chlorosplenium ceruginosum, Lachnea coprinaria, Corticium 
confine, and Poria vaporaria. 
Myxomycetes. — Reticularia lycoperdon and Didymium 
difforme. 
Mosses and Hepatics. — Mr. Wm. Ingham writes : — 
The most striking feature by the River Nidd from Knares- 
borough to Nidd Bridge was the great abundance of the Liver- 
wort Conocephalum conicum. This large and conspicuous 
Hepatic fruits from February to April, and even then the 
fruit is not common, but by the Nidd the plant was crowded 
with fruit in the best condition for ripe spores. 
Another thalloid Hepatic was Lunularia cruciata, which
