Hypomyces lateritius ( syn. Peckiella lateritia ) is a hose fungus from the family of the crust ball relatives (Hypocreaceae), whichparasitizeson the fruiting bodies of various milklings or pigeons, especially irritants . The deformed mushrooms are called stone irritants or deaf irritants .
features
Macroscopic features
The fungus covers the fruiting bodies of the irritant core with a hard coating, the so-called subiculum, and colors them red-brown to ocher. The subiculum does not change color with KOH . The perithecia are formed on the hymenophore of the host and can be recognized as dots that are regularly distributed and sunk in the subiculum so that only the opening can be seen. They are 300–470 µm long and 170–360 µm wide, are yellow-brown to brown and turn yellow with KOH. The secondary fruit form can be found in the field on mummified fruit bodies and forms a white cotton wool mycelium between the lamellae of the host.
Microscopic features
The tubes thickened at the apex are on average 90–150 µm × 4–8 µm in size. The spindle-shaped ascospores measure (15) 21-27 (-30) × (3-) 4-5.5 (-6) micrometers, are unseptate and have a fine black surface.
In culture, the fungus forms slowly growing colonies on malt extract agar , which reach 5-7 mm in a week and consist of a cottony mycelium, white, odorless on both sides and only a sparse aerial mycelium. No thick-walled cells are formed.
ecology
Hypomyces lateritius attacks milklings especially from the Reizker section , especially the Edel-Reizker , Spruce-Reizker and the wine-red pine-Reizker . Furthermore, the camphor milkling , the pink-angular milkling , the larch-Reizker , the red-brown milkling , the Flatter-Milchling , the birch-Reizker and the Nordic Milchling are settled as hosts. The fruit bodies of the hosts are deformed and hard.
distribution
Hypomyces lateritius presumably occurs wherever its hosts, the dairy animals, also occur, for example all over North America from Alaska to central Mexico. In Europe it occurs from France to the Ukraine . In Asia up to Kazakhstan , Kyrgyzstan and Western Siberia. It is also documented from New Zealand .
meaning
In contrast to its relative Hypomyces lactifluorum , which is valued as a market mushroom in Mexico and the USA, Hypomyces lateritius makes its hosts, the Reizker (or other milklings) or deafblings, hard and inedible .
