Veluticeps
Encyclopedia
Veluticeps is a small genus of wood-rot fungi characterized by the production of resupinate to bracket shaped, perennial, tough, brown fruitbodies, that blacken when KOH
solution is applied, and with a smooth to warted or cracked fertile undersurface. They cause a brown rot of wood.http://oldpage.tfri.gov.tw/book/sp98/sp98i416.htm Cystidia

s, such as "Veluticeps veluticeps" would be illegitimate under the International Code of Botanical Nomenclature. The name combines velutum or velutinus, meaning velvelty with -ceps meaning head, combined to mean velvety head, a reference to its velvety hymenium, rather than the actual upper surface (when it actually has a reflexed or bracket shape, which it does not always have).
Potassium hydroxide
Potassium hydroxide is an inorganic compound with the formula KOH, commonly called caustic potash.Along with sodium hydroxide , this colorless solid is a prototypical strong base. It has many industrial and niche applications. Most applications exploit its reactivity toward acids and its corrosive...

Cystidium
A cystidium is a relatively large cell found on the hymenium of a basidiomycete , often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in the...
in the hymenium
Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia or...

Dry rot
Dry rot refers to a type of wood decay caused by certain types of fungi, also known as True Dry Rot, that digests parts of the wood which give the wood strength and stiffness...
genera such as Neolentinus, Heliocybe
Heliocybe
Heliocybe is an agaric genus closely allied to Neolentinus and the bracket fungus, Gloeophyllum, all of which cause brown rot of wood. Heliocybe sulcata, the type and sole species, is characterized by thumb-sized, tough, revivable, often dried, mushroom fruitbodies, with a tanned symmetric pileus...
, and Gloeophyllum
Gloeophyllum
The genus Gloeophyllum is characterized by the production of leathery to corky tough, brown, shaggy-topped, revivable fruitbodies lacking a stipe and with a lamellate to daedaleoid or poroid fertile hymenial surfaces. The hyphal system is dimitic to trimitic. The genus is further characterized by...
