Macoun, I undertook the study of the fungi collected by the naturalists of the Southern Party of the Canadian Arctic expedition. Mr. Frits Johansen had collected about thirty species, storing the fleshy ones in alcohol and preserving the others dry. In addition to the examination of these I have been afforded the opportunity to examine the collections of phanerogams for fungi that might be found in- habiting them. This experience was interesting in several ways. I was surprised at the relatively small number of ‘‘summer stages” of parasitic fungi. On an equal number of affected flowering plants collected in the southern latitudes of Canada there would be a large majority of examples of the stage of fungi reproducing by conidia or “‘summer spores”? of some kind. Most of the fungi inhabiting the arctic plants were found only in the ascigerous or mature condition. Another unexpected difference appeared in the wider range of host plants inhabited by the same fungus species. In the south, as a rule, one fungus at a time inhabits one host plant; in the north, it was not uncommon to find two or three micromycetes on the same individual host plant, especially on those plants that grow in dense rosettes or in the pillar form. On the latter the leaves, though winter-killed or dead, remain firmly attached to the plant for years and doubtless afford it protection. Fungi thus have the opportunity to become established on a plant in successive years. Parasitism does not seem to play much part. There, as here, the mature stage of the fungus seems to be quite saprophytic or, at worst, invading the tissue only when its vitality languishes. At Mr. Macoun’s suggestion I have mide notes of the findings in the important orders of the fungi listed in the available reports of the flora of American arctic regions, other than the one explored by the Canadian expedition. For that purpose the following reports were used:! Meddelelser om Groenland, Bind III, Copenhagen, 1880, containing Oversigt ov Svampe by E. Rostrup, 1888, and Tillaeg, 1891, by the same author. Meddelelser om Groenland, Bind XVIII, Copenhagen, 1896, containing Oest Groenlands Svampe by E. Rostrup, 1894, and Champignons du Groenland Oriental. Meddelelser om Groenland, Bind XXX, Copenhagen, 1907-1911, containing Fungi Groenlandiae Orientalis in Expeditionibus 1898-1902. Determ. E. Rostrup, 1904. Meddelelser om Groenland, Bind XLIII, Copenhagen, 1911-1917, con- taining Fungi Terrestres north of 76° N. Lat. Determ. C. Ferdinandsen, and Systematic List of Micromycetes, Determ. J. Lind. (The speci- mens were collected 1906-1908). The Nares Expedition on the Alert and Discovery, 1875-76, containing enumeration of the Fungi by Rev. M. J. Berkeley, published in the Journal of the Linnean Society, 1878. Harriman Alaska Expedition, 1899, Vol. V, containing Cryptogamic Botany of Alaska, by William Trelease, New York, 1904. 1In the Report of the International Polar Expedition to Point Barrow, Alaska, Washington, 1885, p. 192, Prof. Asa Gray, in a brief report on the Plants, states: ‘‘There was a quantity of fungi preserved in a jar of alcohol, but without notes of color, habit, etc., 80 that the specific determination is in their present state impossible. The specimens, as far as could be told, seemed to include two species of Agaricus and one of Russula.”” 50278—13 4c Canadian Arctic Expedition, 1913-18 Second Norwegian Arctic Expedition in the Fram 1898-1902, Vol. 2, Krist- iania, 1906, containing Fungi collected by H. G. Simmons and deter- mined by E. Rostrup. Duc d’Orleans, Croisiére Océanographique accomplie & bord de la Belgica dans la mer du Grénland 1905. Bruxelles, 1907. 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 been 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 poorly developed flora in an exposed and comparatively arid region 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.1. 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 fogs and 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, where much of the Harriman expedition’s collecting was done, is nearly 500 miles south of the Arctic circle. That so few Alaskan fungi 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.

Fungi 5c The collections enumerated in this report were made between lat. 67° N. 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 line of the chief collecting points runs from near Point Barrow to Bathurst 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 Sadlerochit river andin the northeast corner of Alaska are not separated in the above table from the strictly 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 micromycete 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 number 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 is given. Joun DEARNESS. Lonpon, Ontario, November 27, 1922. 6c Canadian Arctic Expedition, 1913-18 The Fungi of the Arctic Coast of America West of the 100th Meridian Collected by the Canadian Arctic Expedition 1913-18 By Joun Drarness, M.A. MYXOMYCETES. No Myxomycetes were collected by the Canadian Arctic expedition. One species was found by the Harriman Alaska expedition. In the consulted reports of the Greenland expeditions six myxomycetes are listed. PHYCOMYCETES. The Phycomycetes, including the Mucors, Peronogpores, and about a dozen other less important families, must be rare in the arctic regions, for only five species are named in the Alaska report, and seven species in the Greenland lists. None were collected by the Canadian Arctic expedition. ASCOMYCETES. SORDARIACEAE. No species of this interesting family were brought back. They are small plants, nearly 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 69° and 74.30° N. lat., N. Hartz found no less than nine different species growing in the droppings of animals, four of them in Sordarieae and three in Ascoboleae. SPHAERIACEAE. Gnomonia sp. On leaves of Salix Richardsonit Hook. Camden bay, Sept. 1913, 93802. Beak 400-500 yu long, slightly enlarged at ostiole. Too old or too imperfectly developed to determine the species.

Mycosphaerella eriophila (Niessl) Sphaerella eriophila Niessl. Neue Kernp. p. 86. On Erigeron compositus Pursh. Bernard harbour, July 10, 1915, 98960. This species was found on the same host in Greenland. It is reported on Artemisia in western Alaska. Doubtless it is a common arctic species. Mycosphaerella immersa n. sp. Peritheciis immersis, ostiolis erumpentibus, 270 win diam. Ascis 75 x 9-10 y, aparaphysatis. Sporidiis uniseriatis, hyalinis, ellipticis, uniseptatis, non con- strictis, 15 x 8 yu.

Sphaerella inconspicua Schroet. Nord. Pilze, p. 12. On leaves and flower stems of Casstope tetragona (L.) Don. Bernard harbour, August, 1915, 98762. The species is common on this host. Mycosphaerella minor (Karst.) Sphaerella minor Karst. Myc. Fenn. 11, 171. On leaves of Dodecatheon frigidum Cham. and Schlecht. Shingle point, Mackenzie river delta, August 4, 1914, J. R. Cox and J. J. O’Neill, 98824. Gregarious, connected at base by radiating hyphae. Asci 30-33 wu; sporidia 9-12 x3 pn. A form of this species on Saaxzfraga, having larger fruit—asci about 50 x 15 p and sporidia 15-18 x 5 w—and a brown subiculum visibly colouring the affected areas of the leaf and connecting the species with Sphaerella trichophila Karst., was described in Mycologia IX, 346. The distinction between the two species seems to hinge on the bristly appendages and the size of the fruit. On the collections in hand considerable difference in these features are found on the same host plant, making it difficult to determine to which species the Honan should be referred.
