Characters.—Sporidia naked (without any hymenium, perithecium, asci, or sporidiferous flocci), produced beneath the epidermis of plants or within the matrix (Fries).
Properties.—No medicinal substances are obtained from this sub-order. The yeast plant, which Turpin refers to the genus Torula (from torus, a twisted cord), is more probably an imperfect mucedinous fungus, and as such will be noticed herafter (see sub-order Hyphomycetes). The ergot-mould, called, by the late Mr. E. J. Queckett, Ergotaetia abortifaciens, and referred to this sub-order, is considered by Link and some other authorities to be a species of Oidium, and as such will be noticed subsequently (see sub-order Hyphomycetes).
The Elements of Materia Medica and Therapeutics, Vol. II, 3th American ed., was written by Jonathan Pereira in 1853.
