Species Information

Summary:
Features include 1) a tan to ocher to reddish brown, moist to dry cap, 2) crowded, broad, light ocher to rust-brown gills, 3) a pale yellowish brown stem darkening at base, the stem somewhat white-silky from the veil, 4) growth under alder, 5) a brownish spore deposit, 6) large spores, and 7) cheilocystidia with a bill-like extension. Hansen, L.(2) gives Alnicola melinoides (Bull.: Fr.) Kuehner as a synonym of Naucoria escharioides. Moser(1) says Naucoria escharoides ss. Ricken = Naucoria furfuracea ss. Ricken = Tubaria conspersa (Pers. ex Fr.) Fayod, and has a separate heading for N. escharoides (Fr. ex Fr.) Kummer, but does not mention Alnicola melinoides. Note the difference between descriptions on whether cap is striate. Hansen, L.(2) includes it in a part of their key entitled "not or only slightly striate at margin".
Cap:
1-4cm across, convex, later expanded or with margin upturned; reddish brown; slightly appressed-fibrillose, then often smooth, margin [in that part of key] not or only slightly striate, (Hansen), 1-3cm across, convex; light ocher, somewhat yellowish brown when older; somewhat fibrous, (Moser), 1-2.5cm across, convex becoming flat and somewhat umbonate; tan, becoming brownish at center, honey-brown to ocher-brown toward margin; "moist at first, minutely scruffy-hairy", "margin becoming radially lined and wavy", (Lincoff), up to 4cm across, yellow ocher; fibrillose, not striate, (Courtecuisse), pale yellowish to yellowish brown, usually with a pale margin, (Trudell)
Gills:
crowded; colored as cap, (Hansen), light ocher to light cinnamon brownish, (Moser), "attached, almost distant, broad"; yellow to rust brown, (Lincoff), yellowish, (Courtecuisse), creamy white to yellowish brown (Trudell)
Stem:
1.5-4cm x 0.1-0.4cm, pale yellowish brown, whitish fibrillose, (Hansen), 1-5cm x 0.1-0.4(0.5)cm, "pallid-tawny, base turning dark soot brown, somewhat white-silky from veil", (Moser), 2.5-4cm x 0.1-0.15cm, brittle; "pale yellowish to brownish, sometimes with scattered, minute yellow fibers at first", (Lincoff), up to 6cm long and 0.5cm wide, straw to brownish or dark in lower part; fibrillose, (Courtecuisse), yellowish brown, often darker brown toward the base, (Trudell)
Veil:
fleeting (Hansen), makes stem somewhat white-silky (Moser), stem often with whitish veil remnants when fresh (Trudell)
Odor:
mild to strongly acidic (Lincoff), no distinct odor (Trudell)
Taste:
#ERROR!
Microscopic spores:
spores over 9 microns long, almond-shaped with a pointed apex, ornamented; cheilocystidia abundant, enlarged in lower part "and with a narrow extension that sometimes has a slight cap-shaped apex", (Trudell), spores 9-12 x 5-6.5 microns, roughened cheilocystidia 35-50 x 8-10 microns, in section Naucoria which has cheilocystidia acute at apex, often with a filiform appendage (lageniform), (Hansen), spores 9-12(13) x 5-6.5 microns, in section Naucoria which has cheilocystidia with bill-like extension, (Moser), spores 10-15 x 5.3-7.3 microns, elliptic, warty, brownish, (Lincoff), [pleurocystidia presumably absent]
Spore deposit:
brownish (Lincoff), olive-brown (Buczacki)
Notes:
Lincoff says it is "Widely distributed; most common in Pacific NW." It has been recorded from OR (by Kauffman 1925 and Ammirati 1986, as N. melinoides, according to Lorelei Norvell, pers. comm.; and by Zeller(4), 1933). Redhead(5) notes records from BC and states, "Many more species exist in British Columbia and remain to be reported."

Habitat and Range

SIMILAR SPECIES
Naucoria alnetorum and Naucoria bohemica have different cheilocystidia. Other Naucoria or Alnicola species not included here occur in Pacific Northwest: O. Ceska has deposit the following from BC at the University of British Columbia: Alnicola melinoides (the same as N. escharioides), Alnicola salicis (the name as Naucoria salicis), A. bohemica (the same as Naucoria bohemica), A. suavis (the same as Naucoria suavis), A. alnetorum (the same as Naucoria submelinoides var alnetorum), and A. sphagneti. The online Species Fungorum lists the last as a synonym of Cortinarius tubarius.
Habitat
in groups under Alnus (alder), (Hansen), damp alder thickets (Moser), under alder in boggy areas, (Lincoff), fall (Buczacki)
