ngate and Rex apply in Ellis,
_N. A. F._, this latter name to No. 2295 of Schweinitz. Such a reference
is a mistake, judging from Rostafinski's descriptions and from the
description and figure of Albertini and Schweinitz (_Consp. Fung._, p.
86, t. 7, I), and by the testimony of Lister. For further concerning
Rostafinski's species, see under _Physarum gyrosum_, p. 111, _Mon._

Plasmodium scarlet. Sporangia gregarious, sessile, globose or
sub-globose, or sometimes plasmodiocarpous, yellowish or orange,
everywhere, when fresh, spotted with minute scarlet granules; the
peridium thin, more or less rugulose; columella none; capillitium
delicate, generally yellow, with nodules conspicuous, yellow or reddish;
spores violet-brown in mass, by transmitted light pale violet, minutely
roughened, 7-9 mu.

A well-marked species easily recognized by the characters cited. The
extent of lime deposit at the capillitial nodes varies; sometimes very
little. This accounts for Berkeley's generic reference. On the other
hand, Lister makes the rounded lime knots "each knot with a red centre
surrounded by yellow, round, lime-granules" diagnostic. This pied
condition does not come out in any of our specimens. The capillitium in
broken specimens soon fades, tends to white, etc.
