Hyphodontia halonata

Select Illustration

Hymenium

Macromorphology:

Micromorphology:

Spores:

4-5.5 x 2-2.5 µm, cylindric to slightly ellipsoid, thin-walled, smooth, inamyloid, without droplets (herbarium specimens).

Basidia:

12-20 x 4-5 µm, young clavat, mature suburniform with one to two constrictions and one basal clamp each.

Sterigmata:

Four, up to 3 µm long.

Cystidia:

1. Capitate cystidia with an apical cap of exsudat, up to ca. 60 µm long, basal 4-5 µm in diameter, basal thin-walled to thick-walled (2. Moniliform cystidia, constricted like a string of pearls, up to ca. 100 µm long, 3.5-5 µm in diameter, slighlty thick-walled (Clamps:

All primary septa with one clamp.

Hyphae:

Hyphal system monomitic. Hyphae 2-4 µm in diameter, thin-walled to thick-walled (

Habitate and Substrate:

Subboreal to temperate coniferes forests, on rotten wood: e.g. Pinus.

Biogeography:

Hitherto only found in Scandinavia and the Caucasus Mountains .

Remarks:

Of H. halonata are only the following specimens known. The illustrated material from the Caucasus Mountains is well developed and does not deviate from the holotype. Within the genus Hyphodontia only five species have cystidia constricted like a string of pearls (moniliforme cystidia). 3% Phloxin solution dyes them more than the surroundind hyphae:

Hymenium smooth to slightly verrucous 

  capitate cystidia present.......................H. halonata 

  capitate cystidia absent........................H. hastata 

Hymenium distinct odontioid 

  capitate cystidia absent........................H. mollis 

  capitate cystidia present 

    Aculei very small, not more than 1 mm long....H. breviseta 

    Aculei up to 2 mm long, spathulate............H. spathulata
