A brief description of Dacryomyces deliquescens, suited for 
systematic purposes, is as follows: 
Dacryomyces deliquescens Duby. 
Synonym for the oidial stage: Dacryomyces stillatus Nees. 
Basidial fruit-body—gelatinous, convex, rounded, or irregular 
when confluent, often slightly plicate or gyrose, yellow, trans- 
lucent, I-6 mm. in diameter, basal portion emerging from the 
wood at the central point. Basidiospores cylindrical, curved, 
obtuse, 12-15 x 5-6, 1-celled when discharged from the sterig- 
mata but after lying in water soon becoming triseptate and 
4-celled. 
Oidial fruit-body—gelatinous, convex, mostly hemispherical, 
not plicate but when large often irregularly humped up at the 
surface, bright orange, rather opaque, I-3 mm. in diameter, 
basal portion as before. Basidiospores never present. Oidia very 
numerous, embedded in the outer gelatinous layer which deli- 
quesces in rainy weather and sets them free, formed in branching 
chains, cylindrical, curved or flexuose, sometimes forked, usually 
2-celled but forming chains owing to imperfect separation, 
width 2-4, length when 2-celled 12-15, but forming chains 
up to 60, long, sometimes bearing one or two minute oval 
conidia 2m long, contents pale orange with one or two clear 
guttules in each cell. 
Lignicolous, occurring on many different kinds of wood 
especially coniferous woods. Common everywhere, often seen 
in gardens on old pine boards, wooden rails, arbour-work, etc. 
It is to be found all the year round but is conspicuous only in 
wet weather. 
The two forms of fruit-bodies were originally described by 
Duby and Nees as independent species and have always been 
so treated by systematists, the basidial form being called 
Dacryomyces deliquescens and the oidial form D. stillatus; but 
Brefeld has proved that they are nothing but two stages of the 
same species. They may be found separated from one another 
on different substrata, or in separate patches side by side on 
the same substratum, or occasionally intermingled. According 
to Tulasne some of the yellow fruit-bodies may at times be 
shia with red patches of the same nature as the red fruit- 
odies.
