Dry rot be more distinctive in these species than water translocation. Water translocated in this fashion carries nutrients to the extremities of the organism; not, as is sometimes inferred, to simply render dry timber wet enough to attack. Coggins goes into more detail about water movement in "Serpula lacrymans". The perpetual saturation of wood with water also inhibits dry rot, as does perpetual dryness. "Dry rot" would appear to be a paradoxical term seemingly indicating decay of a substance by a fungus without the presence of water. However, its historical usage dates back to the distinction between decay of cured wood in
Serpula (fungus) Serpula (fungus) Serpula is a genus of fungi in the family Serpulaceae. The term was originally defined by Christiaan Hendrik Persoon as a section of the genus "Merulius" in 1801. British botanist Samuel Frederick Gray raised it to genus status in his 1821 work "The Natural Arrangement of British Plants". The name is derived from the Latin verb "serpěre" "to creep". Synonyms include Johann Heinrich Friedrich Link's 1809 "Xylophagous", Christian Hendrik Persoon's 1825 "Xylomyzon", Narcisse Théophile Patouillard's 1874 "Gyrophora", and Patouillard's 1897 "Gyrophana". "Serpula" forms a clade with at least two other closely related genera, "Austropaxillus" and "Gymnopaxillus", the three
