Synonyms:
= Peniophora glebulosa Bres. ssp. cineracea Bourd. & Galz. 1912, Bull. Soc. mycol. Fr. 28: 387.
Macromorphology:
Resupinate, smooth, white or slightly cream-coloured, ca. 50 µm thick, margin thinnig out, under hand lens (10x) pilos by protuding cystidia. Coloured photo in Breitenbach & Kränzlin (1986), picture No. 80.
Micromorphology:
- Spores:
- 7-8 x 2.5-3 µm, narrow allantoid, thin-walled, smooth, inamyloid.
- Basidia:
- 15-17 x 4.5-5 µm, cylindric with a slightly suburniform constriction and one basal clamp each.
- Sterigmata:
- Four, 3 µm long.
- Cystidia:
- Tubular tramacystidia, thick-walled (up to 1.5 µm), 100-150 long, 7-9 µm in diameter. They always arise from basal hyphae. In young ontogenetical stages the cystidia are already thick-walled except the apical part.
- Clamps:
- All primary septa with one clamp each.
- Hyphae:
- Hyphal system monomitic. Hyphae of the subhymenium thin-walled, very short-celled, diameter 2.5-3.5 µm. Basal hyphae thin-walled, 2-3 µm in diameter, running more or less parallel to the substrate. Hyphal branching by subseptal outgrowings or outgrowings of the clamps.
Habitate and substrate:
Mainly on decayed, white-rotten coniferous wood: Pinus, Picea. The type was created by Erica sp. (fide Bourdot & Galzin 1927).
Biogeography:
This species has a northern hemispherical distribution. Nevertheless there are no records from Asian. For new Zealand and Australia Cunningham (1963) only describes the closely related species H. subalutacea. Rick (1959) describes a new variety from Brazil, which also is conspecious to H. subalutacea.
Remarks:
The limitation of Hyphodontia species with narrow allantoid spores and tubular, thick-walled tramacystidia is difficult. Spores size and basidia size are often overlapping in some species:
|
| Spores
| Basidia
|
| H. altaica
| 4.5-6 x 1.5-2.5 µm
| 10-15 x 4-6 µm
|
| H. cineracea
| 5.5-8 x 2-3 µm
| 14-20 x 4-5 µm
|
| H. floccosa
| 5.5-7 x 1.5-1.8 µm
| 12-20 x 3.5-5 µm
|
| H. subalutacea
| 6-8 x 1.5-2.5 µm
| 10-23 x 3-4 µm
|
With the aid of the hymenium suface and the spores size is a practiceable limitation possible:
Hymenium totally smooth
Spores wider than 2-2.5 µm H. cineracea
Spores more narrow than 2 µm H. altaica
Hymenium verrucose or odontioid
Hymenium verrucose H. subalutacea
Hymenium clearly odontioid H. floccosa
