Rodham E. Tulloss The following is based upon material collected during September and early October in the years 2003 through 2006 in and around Gros Morne National Park during and prior to annual fungal forays of the Humber Natural History Society (HNHS). Additional exsiccata supplied by Dr. Andrus Voitk (HNHS) have been utilized for a better coverage of the entire mushroom season; these come from Island of Newfoundland in general as well as from southern Labrador (dwarf willow and seed, photo on right). At present, this list contains 24 possibly distinct taxa. There are probably some taxa represented more than once in this list, and these cases are noted in the entries for the relevant taxa. Two numbered taxa (sp. NFL4 and sp. NFL5) are omitted for the moment because the relevant data is poor. There are probably additional taxa not yet recorded. The list includes some taxa that appear to be circumarctic or nearly circumarctic in distribution -- e.g., A. groenlandica -- and others that, at present, are only known from the region in question. Terms and definitions: DAOM is the Index Herbariorum Code for the Agriculture Canada Herbarium (Ottawa). Definitions of biometric variables can be found through the link at the top of this page. Links on species names connect the reader to relevant species pages. Vascular plants of special interest: Empetrum spp. Habitats of special interest: Empetrum heath: "barrens found on exposed coastal headlands and inlands ridges at altitudes approaching the treeline. Empetrum heath is dominated by carpets of black or pink crowberry, which belong to the genus Empetrum." [Definition taken from Northern Peninsula Ecoregion Brochure.] Amanita subgenus Amanita (spores inamyloid) Amanita sect. Amanita -- Fruiting body developing in eccentric position (above center) in primordium;
hence, stipe with a bulb at the base; lacking a saccate volva.
Although data is absent for several taxa, all taxa in this group should be suspected of containing ibotenic acid, muscimol, or
similar compounds. All photographs for this section are by R. E. Tulloss.

species NFL3.
Pileus grayish brown at first, dark brown at maturity, with striations 25-40% of radius; lamellae marginate; stipe
with black fibrils; subhymenial base without notably inflated cells (e.g., slightly inflated, intercalary hyphal
segments may be present); spores [20/1/1] (11.9-) 13.1 - 15.5 (-18.4) × (11.2-) 11.8 - 13.8 (-17.5) µm,

[Note: It is not known whether the spore measurements of the material seen to date (which had rather common bisterigmate
basidia and was in distressed condition when the spores were measured fresh) is typical of this species.]

22. flavoconia G. F. Atk. var. flavoconia. Cap usually or yellow-orange to red-orange, stipe usually predominantly yellow. Spores: [139/8/8] (6.5-) 6.8 - 9.0 (-10.6) × (4.8-) 5.0 - 7.0 (-8.9) µm, (L = 7.2 - 8.2 (-8.6) µm; L’ = 7.9 µm; W = (5.3-) 5.5 - 6.9 µm; W’ = 6.0 µm; Q = (1.08-) 1.15 - 1.50 (-1.64); Q = 1.21 - 1.43 (-1.49); Q’ = 1.33).) 23 .
[Note: Amanita porphyria Alb. & Schwein. : Fr. is a puzzling species. Schweinitz's watercolor preserved at the Academy of Natural Sciences in Philadelphia shows an entirely gray fruiting body The original description, however, says that the cap is porphyry colored -- brown with tints of red or purple. The partial veil often becomes gray quickly, and there are often gray fibers on the stipe below the partial veil. The North American material varies from coloration similar to the European one to almost olivaceous brown and with the color evenly distributed or giving the strong impression of embedded radial lines. Material from Newfoundland is often paler than material from other parts of eastern North America and contemporary determination of this species is largely based on the gray partial veil and the marginate bulb at the base of the stem.] 24. rubescens sensu auct. amer. boreal. orient. var. rubescens (This entry includes specimens with yellowish underside of the partial veil which do not represent the f. annulosulfurea of Europe. Spores: [40/2/2] (7.0-) 7.3 - 9.5 (-9.8) × (5.6-) 5.9 - 7.0 (-7.3) µm, (L = 7.9 - 9.1 µm; L’ = 8.5 µm; W = 6.4 - 6.6 µm; W’ = 6.5 µm; Q = (1.05-) 1.14 - 1.46 (-1.53); Q = 1.23 - 1.38; Q’ = 1.31).) [Note: This species of eastern North America is not A. rubescens Pers. : Fr. of Europe and is possibly most closely related to A. flavorubens (Berk & Mont.) Sacc. (range: central Mexico to Nova Scotia) and A. rubescens var. alba Coker (range: predominantly SE North America).] Acknowledgments I extend my sincere gratitude to the Humber Natural History Society, the provincial government of Newfoundland and Labrador,
