Oxyporus populinus - Treppenförmiger Steifporling

No. 77 - a finding from the Bavarian Alps.
Widespread but not common species
O. populinus is a perennial Wound parasite on dead or dying hardwoods already in sunny, dry locations. It grows there in tile standing strains in southern Germany preferred to maple, but otherwise also beech, ash, willow, apple, etc. The medium-sized console-shaped, usually around 3 - 8 cm protruding hats are thick and sharp. you are in all parts whitish with the felted top is like overgrown with moss. Some collections have therefore a certain similarity to fruit bodies of Buckelporlings. The pores, however, are tiny and measure 5-7 per mm. Typically, the laminated tubes, which can be clearly seen while the cross (see Figure 3). Lt. H. Jahn should they meet "annual layers.
The species is in Germany in the deciduous forests spread as far, in the Rhine-Main area, it is rather rare. It causes a white rot active. Based on the tube layers and the small pores is O. populinus easily determined. Microscopically it is carried round, small spores, fixed missing buckles on the septa and their encrusted Zystiden. They could be confused with the also pileate O. corti cola with larger pores and more elliptical spores. Occasionally seen in hardwood and resupinate fruit body with the nearly same micro-features such as O. populinus but also elliptical spores. This is Oxyporus obducens , the "crust-shaped Steifporling" which frequently as a variety of O. populinus called and was presented as No. 45 in the blog.
The shown fruiting bodies were photographed in April 2010 on the Isar at Wallgau of ovarian willow trees.

Phellinus punctatus - Polsterförmiger Feuerschwamm

No. 76 - a finding from the Bavarian Alps. only regionally common species
fire sponges are perennial, hard, brown Porling with layered tubes. They grow pileate, effuse-reflex or resupinat. Trama their turns with Potash black promptly. Almost all species have Tramal, brown, thick-walled and tapered cells (setae).
The spores are pale to brownish and usually in the form of circular to elliptical. Ca. 25 different Phellinusarten come in Germany at various deciduous and coniferous trees.
P. punctatus resupinat growing with more or less firmly attached edges. The fruiting bodies are in the middle of plump, pillow-shaped, oblong-narrow, slender and are about 20 - 50 cm long. If you cut them in half, you can see several growth layers. This in the Rhine-Main region rather rare species in addition to their remarkable growth has another special on. If it lacks the thick, pointed "Setea" which are so typical in the genus, throughout. Found only in the hymenium thin, short, zystidenartige cells.
The cushion-shaped sponge fire grows primarily on trunks of dead or dying willows and hazel bushes, rarely in other hardwoods. It is found along forest edges and river flows in swamp forests, but always on thin places in 1 - 2 meters above the ground. The pores are tiny, measuring about 5 - 6 per mm. The species has small, rounded and rather colorless spores.

With practice, it is easy to recognize. Similar, mainly resupinate Phellinus species with which one could confuse them, are much thinner, and grow to more lying on the ground, rotten branches or on the side or bottom horizontal strains. The cushion-shaped sponge
fire can be found on the other hand, always available to tribes by far the ground. In southern Germany, is the type often used and in appropriate habitats.
The presented images were photographed in April 2010 in a willow thicket on the river Isar in Wallgau / Karwendel.
