422 THELEPHORACEÆ Coniophora
1897. C. gelatinosa W. G. Sm., Aldridgea gelatinosa Mass. (from
its gelatinous substance) a.
Broadly effused, fleshy, subgelatinous, sometimes in. thick,
becoming collapsed and rigid. Hym. pallid becoming purple-
brown ; marg. determinate. Spores olive.
Sawdust, extending for several inches, the irregularities of the hymenium due
to the substratum. 5 in,
1898. C. byssoidea Karst, (from its, at first, flaxy condition; Gr.
byssos, fine flax, eidos, appearance) a c.
Irregularly effused, at first grey, then compact; mid. fleshy.
Hym. light to ferruginous yellow, or colour of coffee and milk ;
marg. narrow, somewhat arachnoid or flaxy, whitish.
Forming a biscuit-coloured film sometimes a foot broad on fir-leaves, moss,
earth, etc. ; frequent. 4J in.
LXXXVIII. EXOBASIDIUM Woron.
(From the habit, the spores growing from basidia only with no
true sporophore ; ex, out of.)
Entophytes parasitic on living leaves and stems, which they
deform and hypertrophy. Basidia crowded, cylindrico-clavate,
Exobasidium THELEPHORACEÆ 423
normally tetrasporous, but spores sometimes varying in number from
one to five. The hymenial cells are borne on vegetative hyphæ
which grow in the cellular tissue of the host and form a loose stratum
on its external surface. Spores ovate to elongate-oval, continuous,
rarely becoming septate, colourless. (Fig. 103.) .
Most nearly allied to Corticium, b u t differing m the absence of
a sporophore or subiculum and in being parasitic. Hcoascus an
Ascomycetons fungus, sometimes grows in company
1899. E. Vaeeinii Woron. (from its growth on Vaccinmm and its
Innatereffused, usually orbicular or elongate, often

covered with a white bloom.

LXXXIX. CYPHELLA Fr.
(From the usual shape, like a small goblet, Gr. kuphos.)
Usually small, sometimes almost minute, somewhat membranous
cup-shapel rarely plane, adnate from a central or oblique point,
sometimes with a stem and pendulous.
Hymenium within the cup or disc. Bast-
dia tetrasporous, rarely bisporous. Spores
subovate. (Fig. 104.)
Closely allied to Solenia. C. per-
pusilla is intermediate. Owing to the
strong external resemblance in many
CyphellcB. to certain small species o i Peziza,
a genus of Ascomycetous fungi, it is
necessary to examine microscopically
the hymenium of some of the species
for the decisive characters of basidia
or asci. C. faginea Lib. is British,
but it is an Ascomycete.S
