Peniophorella pallida is a mushroom species from the family of the fold relatives (Meruliaceae). It has carpet-like, membranous fruiting bodies of whitish color and grows mainly on the dead wood of conifers . The species is distributed in large parts of the Holarctic and inhabits meridional to boreal climates there.
features
Macroscopic features
Peniophorella pallida has the resupinate, membranous-waxy fruiting bodies of the genus Peniophorella , which are whitish to ocher or reddish-brown in color. The hymenium is smooth and porous when dry. The edges of the fruiting bodies are fibrous and not clearly contoured.
Microscopic features
Like Peniophorella species, the hyphae structure of Peniophorella pallida is monomitic , i.e. it only has generative hyphae . The 3–4 µm wide hyphae are hyaline , thin-walled and heavily branched, the septa always have buckles . Brownish, drop-shaped secretions are often found on the hyphae. The cystids are fusiform and pointed. With 50–70 × 6–8 µm they stand out clearly from the fruit layer . There are also brown droplets at its tip. The basidia of the species are club-shaped, have four Sterigmata and measure 20–25 × 5–6 µm. They have a buckle at the base . Their spores are roughly sausage-shaped, hyaline and thin-walled. They measure 7-10 × 2.5-3.5 µm, are not amyloid and have an appendix ( apiculus ).
distribution
The known distribution of the species covers large parts of the Holarctic , where it occurs from meridional to boreal climates.
ecology
Peniophorella pallida grows on more or less rotten dead wood of conifers . It is often found in mesophilic beech forests on soils rich in bases, in which there are isolated conifers. The forest pine ( Pinus sylvestris ) is a common host species .
