communi), immutatis persistentibus; fructificatione homogénea,
extus nuda nascente.” He observes, that they differ in many
respects from the Mucedines or filamentous Fungi, with which
they have been confused; especially in being persistent, indefinite
in their manner of growth, of a solid substance, rigid texture,
and modes of reproduction. In this family we find the
well known genera :—Rhizomorpha, Pericotiia ? Ozonium,
Hypochnus, Myxotrichum, Racodium, Helmisporium, Oi-
diuin, Torula, &e. &c. besides several new genera. Lichina,
A g . is also included by the learned author, at least L . confinis;
L. pygmcea being considered a true Alga. Having, however,
studied both species of Lichina very recently, I cannot refrain
from expressing my opinion that they are both Algcc, and
really species of the same genus, their general structure being
the same, and their fructification remarkably similar.
In examining the present species of Monilia, I noticed a
dark granulated mass within some of the joints, which I at
first conjectured might be very minute sporidia. After my
drawing was finished, I observed, on consulting Dr M a r t i u s ’s
Flora Cryptogamica Erlangensis, that he had remarked a similar
appearance: “ Fibrse articulis ovatis, intus massam
opacam demum grumosam continentibus, (quasi sporis).”
P e r s o o n , in his Mycologia Europasa, comprehends under
his Monilia the genera Aspergillus and Polyactis of L i n k ;
and our Monilia he has united to Tonda.
