Fruit-body lacking a well-developed stem, either reduced to a small
lobe or entirely absent 2
2. Fruit-body flattened or disc-shaped, often with warts or veins on
the surface; spores more or less sausage-shaped _Exidia_
Fruit-body brain-like or with irregular bumps, sometimes lobed or
irregular and encrusting 3

ovoid _Tremella_

ellipsoid _Sebacina_

Fruit-body cushion- or brain-like, or with irregular bumps
_Dacrymyces_
~Dacrymyces stillatus~ Nees ex Fries
_Fruit-body_: 3-6 mm.
_Description_:
Fruit-body: cushion or brain-like, often irregular, lacking any
evidence of stem, yellow or orange, gelatinous, covered entirely by
spore-bearing tissue.
Spore-print: yellowish.
Spores: long, cylindrical or oblong, and slightly curved and 12-15 ×
5-6 µm in size; they characteristically have 2 to 4 cross-walls
dividing the interior of the spore (see below).
Cystidia: absent.
_Habitat_ & _Distribution_: Common on all sorts of old wood,
particularly on fence-posts, wooden railway-sleepers and other worked
timber outside, e.g. sides of summer-houses and garden sheds. It is
also found on twigs and branches in woods and copses.
_General Information_: This fungus is found throughout the year, but
it is much more obvious under damp conditions when it is strongly
gelatinised and very soft; when dry it almost disappears. The tissue
bearing the basidia (perfect state) is yellow, when orange there is a
predominance of asexually produced spores called arthrospores
(conidia).
_D. deliquescens_ is only another name for the same fungus. There are
several species of _Dacrymyces_ with which _D. stillatus_ can be
confused, but can only be separated with certainty by using a
microscope. The Coral-spot fungus, frequently found in gardens,
produces gelatinous, pink protuberances on wood especially that of
sycamore, and may easily be mistaken for species of _Dacrymyces_. It
consists entirely of asexually produced spores (conidia) of the
Ascomycete _Nectria cinnabarina_. The perfect state appears late in
the year as grouped, small, blood-red flask-shaped fruit-bodies
containing envelopes of spores. It is quite unrelated to _Dacrymyces_.
