Fernallini
Dacrymyces variicolor Wils.
On old injured wood of an oak tree in ashore wood. 7 April 1839.
Roughish lobed base, pale pea-green when moist, and then gelatinous.
When dry the surface red brown, faintly transparent and shaded as the aperture
of a decidua; covered externally with an opaque layer of a whitish acute
minute subepidermal cells, which are crowded, convex. Internal colony,
filaments having a number of filamentous interlaced bodies, many
of which are numerous, spore-forming. These look protoplasmic as H. Mucor,
for when the receptacle is immersed in water numerous 2-celled spores
are produced.
Dried specimens of Dacrymyces stillater Wils. Fungi, N°486, are
like dried specimens of an plant in some instances, but there is no
change of colour from its reddish-brown hue when moistened; beside,
the D. stillater, buried under water, separates into distinct, subminute
fine filaments.
The black thread must be minute, when viewed as the
habit of Nectria sikkimicarum. The change of colour when dry is very
remarkable.
