Rehm’s Ascomyceten. — The 7th fasciculus is just published,' 
and contains, as usual, some interesting species Amongst these 
is Peziza Ellisiana^ but we must confess that we cannot trace any 
material difference between this and Peziza subtilissima, C. ; the 
sporidia, however, seem to be scarcely mature. It may, perhaps, 
be an immature condition of Peziza laclinodeirna, Berks. We can- 
not help deprecating the rage for new names, without reason, of 
which we have an example in No. 325. This is the Sphceria 
{Diatrype) quadrata, Schwein., and here it appears under the name 
of Myrmceciwn obesum. Undoubtedly specimens were distributed by 
the late Dr. Curtis as Diatrype obesa, Berk. & Curt. ; but why 
Myrmcecium ? We may expect very soon that each species will 
become the type of its own genus. This unfortunate Sphcei'ia has 
a multitude of aliases already. It is the Diatrype exasperans, 
Gerard; the Diatrype brunnea, C. & Pk. ; the Diatiype obesa. 
Berk. & Curt. ; and primarily the Sphceria or Diatrype quadrata, 
Schweinitz. If any alteration in the generic name should really be 
desirable, the specific name quadrata of Schweinitz has priority. 
If it is the object of the new school of continental mycologists to 
ignore and obliterate such respected and honoured names as those 
of Schweinitz, Persoon, and others, they are taking the right steps 
to accomplish their object — for a time — until reason and science 
again united reign. 
N.B. — Since writing the above Mr. Phillips informs us that he 
has succeeded in finding mature sporidia in one of the cups of 
Peziza Ellisiana as published by Rehm, and that they accord per- 
fectly with those of Peziza lachnoderma. Berk. 
Lichens. — We have before us two papers containing descrip- 
tions of new Foreign Lichens by Dr. Stirton. There is also an 
enumeration of small collections of known species from Kumaon 
(India), Calcutta, Ceylon, Isle of Mauritius, South Africa, and the 
collection made by Mr. Trail in the Amazons. No British species 
are included in these papers. 
Mycographia. — It is proposed to issue the Third Part of 
“ Mycographia ” as early as possible in October of the present 
year. The fourth part will not be ready before March or April in 
next year. 
Philadelphia Exhibition. — The “ Department of Agricul- 
ture ” exhibits 200 coloured illustrations of the Genera of Fungi, 
from drawings undertaken for the Department by Dr. M. C. Cooke. 
The selection includes the most important and typical genera, with 
microscopical dissections, drawn to an uniform scale. 
Grevillea. — The present number commences the fifth volume, 
subscriptions for which have fallen due, and should be paid as 
heretofore.
