Hyphodontia altaica
Parm. 1968
Consp. Syst. Cort., S. 211.
Select illustration:
Holotype: GUS, Altai, Telezkoie, on a dead branch of Abies sibirica,
800m, leg. E. Parmasto, 21.08.1959, Nr. 8576, Herbarium TAA.
Macromorphology:
Resupinate, smooth, ochraceous, ca. 300 µm thick, margin thinning out.
Micromorphology:
- Spores:
- 4.5-6 x 1.5-2 µm, cylindric to allantoid, inamyloid, with one little droplet
each.
- Basidia:
- 7-15 x 3-4 µm, young ellipsoid, mature doliform to short clavat, with one
basal clamp each.
- Sterigmata:
- Four, very slender, up to 3 µm long.
- Cystidia:
- Tubular trama cystidia, up to ca. 300 µm long, 5.5-10 µm in diameter, thick-
walled (up to 2 µm), apical thinn-walled, apex obtus. They arise from basal
hyphae.
- Clamps:
- All primary septa with one clamp each.
- Hyphae:
- Hyphal system monomitic. Basal hyphae 2-4 µm in diameter, thin-walled to
thick-walled (
Habitate and substrate:
Rotten coniferous wood in mountains: Abies, Larix.
Biogeography:
Until now there are only two collections known from Asia. Because there are
no records from North Europe and North America, it is possible,
that H. altaica has an Asian distribution.
Remarks:
H. altaica, and H. cineracea can be easily distinguished by the size of
their spores and basidia and also by their different basidiocarps:
Basidiocarp Spores Basidia
H. altaica up to 300 µm thick 4.5-6 x 1.5-2 µm 7-15 x 3-4 µm
H. cineracea up to 50 µm thick 7-8 x 2.5-3 µm 15-17 x 4.5-5 µm
