MOSS AND LICHEN COLLECTING IN THE CATSKILLS. 
George B. Kaiser, 
Most interesting from a cryptogamic view-point is that section of the 
Catskill Mountains which surrounds Haines Falls, New York, where a month 
has been spent in each of the summers of igo8, 1909 and 1910, 
On rocks in the Kaaterskill Clove Ulota Ajuericaiia maybe found in 
excellent fruiting condition in July with Hedwigia albicans, Dicra7ium 
fulvum, Grimmia apocaj'pa, Hypnujn reptile, the lichen Parmelia — 
several species — and many crustose forms of the Lecideaceae. On tree 
trunks Ulota crispa is to be seen everywhere with less frequently the species 
Ludwigii Driunmondia clavellata is also common on this substratum with 
Orthotrichum specios7i7fi, O. sorditwi and O. strangulatu7n, Leucodo7i 
julaceotis and L. sciuroides and the lichen Ra77iali7ia calicaris fastigiata. 
In Mary’s Glen— a Mecca for the bryologist — one walks over a rich 
carpet of mossy greenery, BaT.7.a7iia trilobata appears in deep dark cushions 
with interspersed masses of Dicra7i7i77i scopariii77i and Leucobryum glaucu77i. 
On Q'^Qxy\o^Ptilidiu}7i pulcherri}7tu77i grows luxuriantly with graceful Thuid- 
iu77is and Hyp nu 771 s —that incomparable species H. crista castre7isis nowand 
then occurring though not at its best, as it may be seen on Hunter Mountain. 
Here Neckera pe7i7iata abundantly fruiting grows out from the tree trunks in 
graceful curves and after a rain the lichen Sticta pul77io7iaria with its 
emerald stag-horn branching, is most conspicuous. In boggy places 
Dicra7ium U7idulatu77i forms broad silken patches with Hypnu77i Schreberi, 
and the less frequent Dicra7iu7n Dru77i77iondii, while the rocky bed of a 
stream is beautified with Brachytheciimi rivtilare, M7iiu77i pu7ictatu7n 
el at 11771, Fo7iti7ialis and Scapa7tia. 
Near Sleepy Hollow, where Rip Van Winkle is said to have taken his 
long nap, you may find wet ledges where Bryu77i bi77U{77i is mature in July, 
and in the deep surrounding woods grow those showy mosses Hyloco77iiu77i 
proliferu77i , H. triquetru77i and rarely H. brevisostre. The exposed rocks 
are rich in lichens belonging to such genera as Gyrophora, U7nbilicaria and 
Colle)7ia, and Rhaco)7iitriu77i 77iicrocarpu7n with Andreaea Rothii may also 
be found. 
On High Peak, Fo7iti7ialis giga7itea, P'rullania Asagrayafta and 
Dicranu77i fuscesce7is are not infrequent, and lichens — several species of 
Clado7iia, Us7iea barbata and Bryopogo7i jubata abound. In all this 
section the Peltigeras are common over mosses, rocks and soil, beginning 
to fruit in July. The bright green thallus of P. aphthosa is particularly 
beautiful. Sticta a7nplissii7ia and Leptogium tre/7ielloides occur more 
rarely. The moss Oncophorus \Vahle7ibergii was found fruiting in the
