 Some Alaskan and Yukon Rusts, The Plant World, Vol. 14, 233, 1911, by 
 J. C. Arthur. 
 
 So far as I know these are the only reports upon collections of American 
 arctic fungi. There have V)cen other collections of phanerogamous plants but 
 usually if the collectors of such plants are not looking for fungi they remove 
 discoloured and deformed parts when they do not or cannot select clean, healthy- 
 looking specimens. 
 
 Anyone who has observed the greatly varied and abundant fungus flora of 
 rich woods in southern Canada and contrasted it with the scanty and pooily 
 developed flora in an exposed and comparatively arid ngion is prepared to 
 believe that within the Arctic circle the fungi will be very meagerly represented. 
 
 In the report on the cryptogamic botany of Alaska published for the Harri- 
 man Alaska Expedition in 1903-04, the editor, Dr. William Trelease, notes that 
 up to that time only 14 species of fungi had been listed.' Commenting thereupon, 
 he says: "The fact remains that almost nothing is known of the fungus flora of 
 Alaska and yet conditions are favourable for a development there of a large 
 representation of this group of plants." He referred to the rainfall and fo^ 
 aud mists common on the long coastal region favouring as they do a large and 
 varied phanerogamic vegetation. Besides, the lower coast of Alaska from Sitka 
 and Yakutat to Kadiak, v^here much of the Harriman expedition's collecting 
 was done, is nearly 500 miles soMth of the Arctic circle. That so few Alaskan 
 fu. had been enumerated prior to 1900 is the more surprising in view of the 
 fact that at the same date no less than 386 Alaskan species and varieties of their 
 congeners — the lichens — had been listed.' 
 
 Greenland's long coast-line both on the east and west sides has been explored 
 at many points by scientists connected with several Danish and other expedi- 
 tions; and while, doubtless, there will yet be important additions made, its 
 fungus flora is much more completely studied than that of any other extensive 
 region of arctic America. , In making comparisons it must be borne in mind, 
 however, that its southern point is more than 450 miles south of the Arctic circle.

 The collections enumerated in this report were made between lat. 67° X. 
 and lat 77° N., chiefly along the northern coast-line of the Yukon and Mackenzie 
 districts; the positions of most of the localities are stated in the introduction 
 to Part A of Vol. V. The median Une of the chief collecting points runs from 
 near Point Barrow to Eathurst inlet, a distance, following the coast, of over 1,200 
 miles and averaging about 150 miles north of the Arctic circle. The collections 
 made in the territory near the mouth of the Sadlcrochit river and in the northeast 
 corner of Alaska are not separated in the above table from the strictlj' Canadian 
 ones. 
 
 The time and locality of collection of the plants herein listed are given, as 
 exactly as the available data permitted, and, further to identify the particular 
 plant on which the micromyeete was observed, the number of the plant as 
 preserved in the National Herbarium, Victoria Memorial Museum, Ottawa, 
 is added. Thus under Pleospora arctica, 98416 is the herbarium numljcr of the 
 particular specimen of Oxytropis campestris var. sordida upon which this fungus 
 was studied. 
 
 Mr. Frits Johansen was the collector in all instances where no other name

 The Phyconiycetes, including the Mucois, IVronospores. and al:i)ut a

 five species are named in the Alaska report, and seven species in the Greenland

 Xo species of this interesting family w<'re brought back. They are small 
 plants, iiearlj" all of them growing in the ordure of animals. It is extremely 
 probable that several of them are existent in the territory. In the Amdrup expedi- 
 tion to northeast Greenland, between tjt)° and 74.00° N. hit., N. Hartz found 
 no le.'s than nine different species growing in the droppings of aninuds, four 
 of them in Sordarieae and three in Ascoboleae.

 On Dnjas itiUgri folia M. \ahl. Hernard iiarbour. July "), H)10. 
 
 In the dense mass of small revolute leaves three fungi were found, namely 
 Mi/coftphaerella pachyasca, Pleospara sp., and a few leaves with a Maxxaria-like 
 species which is prol)at)ly Massarina Dryadis Hostr. 
 
 In the original description Rostrup tloes not give the measurenieiit.s. The 
 sporidia here were 3-septate, constricted, 30-35 m lotig and 15 /u wide in the 
 widest part. Rostrup, found his species on dead leaves of Dryas from Greenland. 
 Trelease found what he thought might be Rostrup'.s species on Dnjus integrifolia 
 collected by Murdoch at Point Barrow, Alaska, upon which he makes the remark 
 "not entirely mature." 
 
 The collector's note reads: "A yellow funcus-blight turning the leaves of 
 the common Dryas a yellow colour." From tl.. material examined I could not 
 determine which, if any, of the fungi found caused the blighting of the leaves.

 Thi.s species seems to be conmion on willows in northern Furoi)e. Tlie onlv 
 otiier American collection I have seen was made liy Dr. Hou>e, on Hald mountain 
 in New York Stat(>. 
 
 Not numy of the Pezizin;ie are directly parasitic, at least in their ascigerous 
 staue, but Hostrup has provi'd that in Denmark, where he found Schrdihrris fuU- 
 iji/.n.-^ii on several species of willow, it is truly i)arasitic and that it killed affected 
 braiiches in a short time. 
 
 In Mr. Johansen'.s collection at Collinson poiiit a few pycnidia of the 
 innidial stage were observed on the same brancht s with the mature i)lants.

 This fungus was sought in both Septoria and Rhabdospora. The leaves do 
 not sec^ olH truly maculat... If the tissues of the host were known to.be dead 
 when they were attacked by the fungus, an invest.gator would look for ,t m the

 the lower Coppermine, February, J91.^., by Mr. V. Johansen, ami at I'.sc.ipe 
 rapids on the same river by Dr. : M. And.Tson in February, 19 G, furnish an 
 unsolved problem. Mucedo-like i.-fts, concolorous with the dead leaves were 
 found on nearly ev-ry leaf of th<' twigs collected but sjiore? were not found 
 in situ Failure > >e functions of the twig may have caused the deijth ot 
 the leaves and dL .tions of the latter strengthened this suiiposition. 1 sub- 
 mitted affected material to Mr. J. R. Weir, Forest Pathologist at NVashington, 
 DC who replied that he had not before seen spruce leaves in this condition. 
 He is disposed to agree with me that the fungus is saprophytic. A distorted twig 
 taken at the first named collection suggested to Mr. Jtihansen the effects pro- 
 duced by some species of Peridermivm. In it I found the sloughs of Lhermcs- 
 like insects but nothing else.
