Eventually, the term "dry rot" came to apply to only one or two fungi the main one being "Serpula lacrymans", in the majority of texts dealing with the subject, predominantly from the United Kingdom. This type of fungal decay subsequently also became known as 'true dry rot'. It has even been proposed to use the term "water-conducting fungi" in the category of "brown rot" rather than "dry rot". However, although the fungi such as these can transport water, it is disputed that it can use this water to increase the moisture content of otherwise dry wood. Whilst it may be disputed as the citation notes, the epithet 'lacrymans' is derived from the Latin word 'lacrymare', meaning 'to weep' and most surveyors of rotted buildings have noted the tear drops formed by the fungus as water forms on the hyphae. These water droplets are photographed in Rentokil's book "Decay of Timber in Buildings" Figure 24. There is, however, no evidence these small amounts of water on the hypae cause a significant increase in the moisture content of otherwise dry wood.
