Image de Trémelle à spores jaunes

Description :

Slo.: pahljaasta solzovka - Habitat: Dry mountain pasture with stumps and logs of cut down Picea abies trees, southeast oriented modestly inclined mountain slope, calcareous ground, full sun, fully exposed to precipitations, average precipitations ~3.000 mm/year, average temperature 7-9 deg C, elevation 615 m (2.020 feet), alpine phytogeographical region. - Substratum: dead stumps and logs of cut down Picea abies in its initial stage of disintegration. - Comments: This is a very common species in Trenta valley. In wet and warm winters, like present one, one can see tens and tens of fruit bodies on a short walk through mixed woods. Fruit bodies have whitish inconspicuous rudimentary 'stalk' (point of attachment to the substratum). However, reliable distinguishing among different orange species of this genus without microscopy is difficult. Dimensions and number of septa of spores is important. - Growing solitary and in groups of confluent fruit bodies; more than a dozen of them scattered around; dimensions up to 6 x 4 cm and 3 cm thick; taste and smell indistinctive; SP abundant, yellow; many times growing together with Gloephyllum separium on the same logs. - Spores smooth. Dimensions: 18,7 [21,1 ; 21,9] 24,3 x 6,4 [7,1 ; 7,4] 8,1 microns, Q = 2,6 [2,9 ; 3] 3,4; N = 50 ; C = 95%, Me = 21,5 x 7,3 microns. Olympus CH20, NEA 40x/0.65, magnification 400x, in water.
