THE ESSEX NATURALIST.
DASYSCYPHA SOPPITTII Mass.
I have found this abundantly on dead oak leaves in Epping
Forest, but never on any other leaf. It is readily known from
allied snow-white species by the single septum occurring in a large
proportion of its spores.
DASYSCYPHA CRUCIFERA (Phili.) Sacc.
A minute snow-white species found on November 5th, 1939,
in Knighton Wood. In a handful of mixed leaves this species
was found on several dead hornbeam leaves and on the wings
of hornbeam fruits, while Dasyscypha Soppittii occurred on
several oak leaves. I could find no sign of either species straying
on to the chosen host of the other. The perfectly formed
octahedral crystals (up to 8μ across) poised on the tips of the
external hairs of this species provide a fascinating microscopic
subject.
LACHNELLA LEUCOPHAEA (Pers.). Boud.
This was found abundantly on a heap of dead stems of an
umbelliferous plant in a chalk-pit at Strethall on April 7th, 1939.
TRICHOSCYPHA CALYCINA (Schum.). Boud.
I have found no Essex record of this abundant species which
occurs wherever there are larches. It was found on larch twigs
at Piercing Hill in May, 1937, and in the greatest profusion
in the larch plantation at Bartlow Hills in July, 1939.
TRICHOPEZIZA GREVILLEI (Berk.). Sacc.
A minute species, of which a dense cluster of some fifty
ascophores was found on a dead umbelliferous stem near
"Slades," Kelvedon Hatch, on the occasion of the Club's visit
on May 20th, 1939.
MOLLISIA LYCOPINCOLA Rehm.
Was found on May 7th, 1939, on dead stems of Lycopus
europaeus in Hatfield Forest. This find is of particular interest,
as it appears to provide the first recording of the species for
this country. I have this year (1940) found this species in
Knighton Wood, on the same host-plant.
MOLLISIA MINUTELLA (Sacc). Rehm.
This I believe correctly names the Mollisia which occurs
abundantly in early summer on dead stems of Epilobium
