Species Information
Summary:
Distinguishing features are the blue gray to blue color of cap, pores, and stem. Neoalbatrellus subcaeruleoporus was differentiated in 2016 from Neoalbatrellus caeruleoporus which occurs in the northeastern United States and eastern Canada (including Quebec and Nova Scotia). N. caeruleoporus has a deeper blue color and larger spores (see SIMILAR for details) and is differentiated by molecular evidence.
Odor:
"sweetly fungoid or not distinctive" (Audet)
Taste:
"mild and slightly sweetish to slightly peppery" (Audet)
Microscopic:
spores 4.0-4.8(5.0) x 3.4-3.6(4.0) microns, broadly elliptic to nearly round, smooth, inamyloid, thin-walled, colorless, typically with one large droplet, with a relatively long tapered apiculus; basidia 4-spored, 23-32(44) x 5.6-7.4, slenderly clavate to nearly cylindric; hyphae monomitic, 3-9 microns wide, sometimes inflated to 20 microns wide, simple-septate, walls colorless, thin, inamyloid, hyphae of pileipellis 4-5 microns wide, repent or a loose palisade, many with oily contents, terminal cells mostly 30-40 microns long, cylindric to clavate (up to 5.5 microns wide) or sometimes irregularly shaped cells about 15 x 5 microns, sometimes with yellow-brown contents, gloeoplerous hyphae scattered in context, up to 7 microns wide, with refractive, almost colorless to pale yellow contents, hyphae of trama parallel, 2.4-5.2 microns wide, "sometimes with resinous deposits interspersed between hyphae and some gloeoplerous hyphae 3-6 microns in diameter", (Ginns(1)), spores (3.3)3.6-4.7(5.1) x (2.8)2.9-3.7(3.9) microns, amygdaliform [almond-shaped], elliptic to nearly round, smooth, inamyloid, colorless, thin-walled, "with a relatively long apiculus"; basidia 4-spored, 25-33 x 6-7 microns, narrowly clavate; hyphal system monomitic, gloeoplerous hyphae in context and trama, (Audet)
Notes:
Neoalbatrellus subcaeruleoporus is found in BC, WA, OR, and CA, (Ginns(1)).
Habitat and Range
SIMILAR SPECIES
Albatrellopsis flettii has white to pallid pores and thicker flesh up to 1.5cm. The cap is larger and spores may be weakly amyloid. |Neoalbatrellus caeruleoporus is not known to occur in the Pacific Northwest and is differentiated by molecular evidence. Selected comparative points are the following. |1) N. caeruleoporus has a cap that is up to 15cm across, grayish blue to violaceous, aging tan to light ochraceous brown, when dry becoming brownish, with the entire fruitbody often turning cinnabar orange, whereas the cap of N. subcaeruleoporus is up to 6cm across, light blue to pale blue, often glaucous with reddish orange areas where damaged, when old or in cracks, and on drying it becomes "brown or brown to black, with tubes and context over time turning very slowly cinnabar orange". |2) N. caeruleoporus has fresh tubes 0.2-0.5cm long that are grayish blue, whereas N. caeruleoporus has tubes 0.07-0.2cm long that are colored as the cap or paler, "becoming orangish or rusty irregularly or where damaged". |3) N. caeruleoporus has flesh that is white and dries typically pale orange but also pallid or orange pink, whereas N. subcaeruleoporus has fresh flesh that is white to pale wood brown, "slowly discoloring after a few hours in open air to pale ochraceous buff, light pinkish cinnamon, or light vinaceous cinnamon", and dries white to pale orange (when exposed). |4) N. caeruleoporus has a stem that is lateral when young, and is colored deep indigo-blue, whereas N. subcaeruleoporus has a stem that is not lateral, and it colored as the cap or paler. |5) N. caeruleoporus has flesh that does not discolor in 2% KOH, whereas N. subcaeruleoporus has flesh that with 3% KOH is pale or light pinkish cinnamon, darkening over time. |6) Spores of N. caeruleoporus measure 4.8-5.6 x 3.8-4.2(4.8) microns or in another measurement 4.6-5.6 x 3.8-4.3 microns, whereas spores of N. subcaeruleoporus in two measurements are 4.0-4.8(5) x 3.4-3.6(4) microns and 3.6-4.7 x 2.9-3.7 microns. |7) Spore apiculi of N. caeruleoporus are obvious but small, whereas spore apiculi of N. subcaeruleoporus are relatively long and tapered. |8) Basidia of N. caeruleoporus are 33-48 x 6-8 microns whereas basidia of N. subcaeruleoporus are 23-32(44) x 5.6-7.4 microns. |9) Gloeoplerous hyphae are not seen in N. caeruleoporus but are scattered in the context (and seen in the trama) in N. subcaeruleoporus. (Audet(2)).Habitat
annual; single to cespitose, some small clusters with stems confluent, on soil associated with conifers, two collections on woody debris or on very rotten wood, (Ginns(1)), arising from deep in forest duff, mid-September to mid-December, associated with conifers, (Audet)
