Gloeophyllum

Gloeophyllum genus 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 under surface. The hyphal system is dimitic to trimitic. The genus is further characterized by the production of a brown rot of wood^[1][2]. Phylogenetically, it along with several other brown rot Basidiomycota, Neolentinus, Heliocybe, and Veluticeps form an order called the Gloeophyllales^[3][4][5].

The most frequently encountered species in the Northern Hemisphere is Gloeophyllum sepiarium[1], which is commonly found in a dried state on both bark-covered and decorticated conifer stumps and logs, timbers on wharfs, planks on unpainted wooden buildings, wood bridges, and even creosoted railroad ties.

Etymology

The name Gloeophyllum combines "gloeo-" a reference to anything sticky, and "-phyllum", a reference to the lamellae. It is probably a combined reference to the fact the lamellae in the type species, G. sepiarium, and other original species, appeared to be stuck together forming anastomosing bridges, to the point of forming a daedaleoid pattern. There is nothing sticky about the actual fungal fruitbodies. The name was originally spelled Gleophyllum but was soon changed and the current spelling is sanctioned.
