Synonyms:
- = Odontia aspera (Fr.) Bourd. & Galz. 1927, Hym. de France, p. 428.
- = Grandinia aspera (Fr. 1874, Hym. Eur., p. 627.
- Lectotype: Norway, near Christiania (Oslo), on leaves of Fagus sylvatica, leg. M.N. Blytt, Herb. E. Fries, Herbarium UPS.
Macromorphology:
Resupinate, odontioid, white to yellowish, margin thinning out, aculei up to ca. 500 µm high, apical slightly fimbriate, standing separated with smooth hymenium between the aculei. Color photo in Breitenbach & Kränzlin (1986), photo No. 82.
Micromorphology:
- Spores:
- 5-6.5 x 3.5-5 µm, ellipsoid, ovoid, thin-walled, smooth, inamyloid, with one big droplet each.
- Basidia:
- 118-30 x 4-6 µm, young clavate, mature suburniform with one to two constriction and a basal clamp each.
- Sterigmata:
- Four, up to 3.5 µm long.
- Cystidia:
- Capitate cystidia up to 35 µm long, 5-6 µm in diameter. They are located in the hymenium or subiculum and have a basal clamp each. The morphology of the cystidia is very variable. They may be present in big number or only scanty. Young ontogenetic stages may be difficult to distinguish from young basidia. The enlarged apex may be naked or covered with an hyalin or granulate exsudate.
- Clamps:
- All primary septa with one clamp each.
- Hyphae:
- Hyphal system monomitic. Basal and subhymenial hypae 2-4 µm in diameter, thin- to slightly thick-walled (Aculei:
- Aculeal end hyphae are very often capitate and may be incrusted with crystals.
Habitate and substrate:
On rotten wood mostly of conifers: Picea, Abies, Pinus, Larix. On angiosperms: Fagus, Betula, Fraxinus.
Biogeography:
The investigated specimens are from the northern hemisphere. More reliable records from Spain and Japan are from Telleria (1980), Ryvarden (1976) and Furukawa (1974).
Remarks:
H. aspera is difficult to distinguish from H. rimosissima micromorphologically. The sizes of spores and basidia of both species are overlapping and both have capitate cystidia. The best criteria for determination is in this case the macromorphology. H. aspera has in contrary to other odontioid Hyphodontia species a smooth hymenium between the aculei.
