I- HALLUS yellowish fuliginous-olive when wet, much
darker when dry, very thin and easily separating from the matrix,
forming small irregular patches 2 or 3 lines or more
broad both on the upper and under surface of the leaves of
Box, Laurel, Phillyrea and other evergreens, consisting of 2
distinct strata, of which the inferior is composed of radiating
articulate or inarticulate variously branched irregular and
sometimes moniliform filaments; the superior not always extending
so far as the subjacent stratum and consisting of close-
packed minute cells, which usually have a distinct endochrome.
Perithecia globose above, but flattened below, cellular like the
upper stratum, more or less collapsed above. Nucleus tinged
with very pale red, consisting of delicate paraphyses and rather
short often very irregular asci, which are much constricted
below, and contain subcymbiform triseptate colourless sporidia.
- The presentcurious production was first detected at Rushton
in Northamptonshire on Box and Laurel in the beginning of
Aug. 1848, and it has since been found by Mr. Churchill
Babington at Cambridge, and by Mr. Mitten on Phillyrea
and other evergreens at Hurstpierpoint in Sussex. It is
probably extremely common, but does not seem to have been
observed before, either in this country or on the continent,
and its affinities are very puzzling. It resembles in outward
appearance some species of Asterina, a genus of Fungi established
by Dr. Leveille, and at present entirely extra-Euro
