with Mr. Murphy and Mr. Louis W. Anderson, also of the 

 Torrey Botanical Club, to whose helpfulness with his auto- 

 mobile I owe many excursions to remote places for collecting. 

 We visited several spots, along the moraine extending east of 

 the town toward Siasconset, on the ocean beach and about 

 Miacomet Pond to the south, and on sandy hills to the west. 

 Cladoniae colonies proved to make up a large proportion of the 

 vegetation of the island. C. Boryi was common and almost 

 everywhere fruiting. A novelty to me was C. rangiferina, f. 

 leucitica, in which some of the podetia diverge from the normal, 

 tall, sterile forms, to shorter, fastigiate, fruited stalks, found 

 near Gibbs Pond. C. impexa, f. laxiuscida, and C. mateocyatha, 

 were species I do not find every day. Since these are the first 

 Cladonia records, for Nantucket, under modern classification 

 of the genus, I give them, complete, as determined with the 

 aid of Dr. Evans, and, in a few cases, of Dr. Sandstede. 



Gibbs Pond : C. cristatella, f . Beaiwoisii; C. Boryi, f . reticu- 

 lata, fruiting; C. uncialis, C. rangiferina, normal and f. leucit- 

 ica; C. caroliniana, f. dilatata; C. tenuis, C. mitis, C. papil- 

 laria, ff. molariformis , and papulosa; C. clavulifera, f. pleuro- 

 carpa; and C. Grayi. 



Altar Rock Hill: C. Grayi, C. verticillata , f. evoluta; C. 

 caroliniana, f. dilatata; C. mateocyatha, (an American species 

 published by Robbins in 1925, from Buzzard's Bay material, 

 and which I have run across rather rarely, on Montauk Point, at 

 Commack, L. I., and Charlottesburg, N. J.); C. tenuis, C. im- 

 pexa, ff. laxiuscula and condensata ; C. cristatella, ff. Beauvoisii 

 and vestita, and excellent specimens of the pretty, pseudo- 

 cupped f . scyphulifera, published by Dr. Evans in 1935 ; C. clavu- 

 lifera, f. nudicaulis , and C. mitrula. 



On the moraine a mile and a half west of Nantucket village : 

 C. tenuis, C. rangiferina, some fruiting; C. Boryi, f. reticulata, 

 mostly fertile; C. mitis, some fertile, which is not often the case 

 south of Cape Cod; C. caroliniana, C. uncialis, C. furcata, var. 

 racemosa; C. macilenta, f. styracella; C. papillaria, ff. molari- 

 formis and papulosa; C. piedmontensis, f. obconica, a species 

 which I do not find often, although its small size probably 

 causes it to be overlooked ; C. verticillata, f . evoluta; C. cristatella, 

 ff. Beauvoisii, vestita, pleurocarpa, and ramosa, the last un- 

 common, in my experience, and very pretty, with its numerous
