Image of White Cheese Polypore

Description:

Slo.: snenobeli sirovec - Habitat: Mixed light forest, former pasture, Fagus sylvatica, Picea abies, Betula pendula, Corylus avellana dominant; modestly inclined mountain slope, cretaceous clastic rock (flysh) bedrock, relatively dry and partly sunny place, partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 550 m (1.800 feet), alpine phytogeographical region. - Substratum: fallen dead branch of Betula pendula lying on ground. - Comments: Two sporocarps present; pileus about 2.5 - 3 cm wide; tube layer very thin compared to context; smell characteristic, pleasant, aromatic; flesh cheesy but tough when dry; SP none, spores taken directly from pore surface using a soft, moist brush. Spores apparently do not fit to expectations well. They seem to be too wide, but characteristic smell and typical hypha with short side branching (Ref.:(1)) make the determination almost certain. - Spores smooth. Dimensions: 4.5 (SD = 0.3) x 2.2 (SD = 0.2) , Q= 2.0 (SD = 0.18), n = 30.
