A species whieh. examined superfieiaUy, may be passed over as Hptoslrona junceum, differing merely in its more
shmmg pen hecram. The spores are, however, of a very different form, and many times larger. In that speeies
as pubhshed m Bntish Fungi (No. 197), and by Madame Libert (No. 260), they are extremely minute and
obtuse at either extremity ; the perithecium also is more closely eeUidar. Iu the specimens publisl.ed by Klotzsch
and Fnes (m “ y copj at least), there is no fructification. I t resembles also. externaUy, L epM rmm vulgare but
there is as decided a difference as in the fonner case between the spores. ’

he production pubhshed by Fries, which exactly accords with specimens gathered in Northamptonshire to bé
the type of the species Both Desmazicre’s (No. 984), aud Mougeofs, and Nestler's (No. 662) plants appear to
me qmte different. Unfortunately m neither have I been able to detect fructification. In Mougeofs plant the
pentheem are strongly eoUapsed. which is by no means the case with that of Fries; aud that of Desmaziire
approacnes Sp. maculaformis.
The genus ftpW ie nm is here considered as comprisiug such species of the geuus ftp/neroa as have simple
spores, never mcluded in asci, such as Sp. acuta, &c.

The species is nearly allied to Sp. vagurn, Nees, from which it differs merely iu'havffig ooustaiitly a siuMe
globose uuc eus in each articulation, presuming that Corda’s figure, pubUshed in the same year with that iu the
Annals of Natural History, is the plant of Nees.

I have seen a single imperfect specimen oiby, which is scarcely more than sufficient to determine the genus.
I believe it, however, to be the species of De Candobe, above cited.

AUied to P. scuteUata and P . umbrosa, but larger than either. The bristles are short and somewhat flaccid,
in which it differs strikingly from the former species, as also in its broader sporidia. From the latter it
differs principaby in its larger size and less conspicuous bairs. I am not able, in tbe absence of authentic specimens,
to compare the sporidia ; but if that species be the same with P . trechispora. Berk., and Broome, which is not
impossible, tbe difference is considerable.
