Synonyms:
- = Fibrodontia gossypina Parm 1968, Consp. Syst. Cort., S. 207.
- Holotype: Kaukasus, Krasnodar, Slaviansk, Kramyi Les., on Fraxinus excelsior, leg. E. Parmasto, 28.09.1966, TAA 19751, Herbarium TAA.
Macromorphology:
Resupinate, odontioid, ochraceous, aculei up to 300 µm long, apically penicillate, very densely standing, often several aculei grouped together.
Micromorphology:
- Spores:
- 3.5-4 x 2.5-3 µm, ellipsoid, ovoid, thin-walled, smooth, inamyloid, without droplets.
- Basidia:
- 10-14 x 3.5-5 µm, suburniform with one basal clamp each.
- Sterigmata:
- Four, up to 2.5 µm long.
- Cystidia:
- Tubular tramacystidia, several 100 µm long, up to 5 µm in diameter, thick-walled (up to 2 µm). The tramacystidia arrise only from the subiculum.
- Clamps:
- All primary septa with one clamp each.
- Hyphae:
- Hyphal system pseudodimitic. Hyphae of the subhymenium thin-walled, 3-4 µm in diameter. Subicular and aculeal hyphae thick-walled (0.5-2 µm), 3-5 µm in diameter, yellowish pigmented, incrusted with big crystals which are not soluble in 5% KOH solution. Substrate hyphae slightly thick-walled (Aculei:
- Aculei consist of thick-walled tramacystidia which have thin-walled and obtuse endings. They make the hyphal texture look like if it was dimitic. Sometimes the tramacystidia have secondary septa. The tramacystidia are wrapped by big crystals.
Substrate and habitate:
Moist deciduous forests or swampy forests. Substrate is rotten angiosperm wood: Fraxinus, Populus, Ulmus, Fagus, Corylus, Salix, Quercus, Parrotia.
Biogeography:
This species is distributed in Europe and the asiatic neighbour parts of Europe. It was never recorded from boreal areas. Some records are from Africa, Eastasia (Nepal, Thailand) (Hjortstam 1982) and Middle Amerika (Nakasone 1990).
Remarks:
H. gossypina was very often conected with poroid species of the genus Schizopora, which have also very long and thick-walled hyphae. Their basidiocarps therefore were called pseudodimitic or dimitic (Eriksson et al. 1984). Parmasto (1968) introduced the genus Fibrodontia for odontioid species with pseudodimitic hyphal system and hyphodontioid characters. Because Fibrodontia can not be delimited clearly from Schizopora I agree with Hjortstam (1990) who combined F. gossypina into Hyphodontia.
A unique type of crystals and the complete absence of hymenial cystidia clearly delimits H. gossypina from Schizopora species. Schizopora species have only hymenial cystidia and no tramacystidia. Within Hyphodontia only three species have the special type of crystals, which surround tramacystidia.
