“Ascochyti pisi, a Disease of seed peas,” published in the 
Ohio Naturalist for April 1906 (6:507-512) by J. M. Van 
Hook, reports the exceptional blighting of peas throughout Ohio 
during the season of 1904 and 1905. It is noted as the most 
important thing in connection with the life history of the fungus, 
that it grows through the husk into the seed. Frequently, when 
the pod contains no seed, the mycelium will grow through, form¬ 
ing similar spots on both sides of the pod. When the mycelium 
passes into the seeds brown spots are formed on the surface. 
Pycnidia are formed on the dead areas of the stems, leaves, 
pods, and seed, and even on the dead stems and branches. Cul¬ 
tures are reported; also seed treatment with mercuric chloride 
and with formalin, the results for the most part not only un¬ 
successful but negative. As hosts are named all the examined 
varieties of the common pea; but the reported hosts Medicago 
sativum, Cicer arietinum, Phaseolus vulgaris and Vicia villosa 
were here free.

Gal.; P. purpusii P. Hen.; P. arabicola E. & E.; and Uromyces 
oblonga Vize.

W. C. Sturgis, under the title “Remarkable occurrence of 
Morchella escalenta (L.) Pers,” says: “On September nth the 
writer was skirting the precipitous side of a mountain at an 
altitude of about 7,000 feet, and while passing through what 
had been a fairly good growth of aspens and small spruces, a few 
fine specimens of Morchella were noticed. Further search re¬ 
vealed the presence of these plants literally in hundreds. A fire 
had passed across the mountain in June, 1904, leaving only 
skeletons of the trees standing and charring the ground to 
such a depth that no trace of green vegetation had since ap¬ 
peared. Yet under these unfavorable circumstances and at a 
season when snow had already fallen not far from the locality, 
a bushel of Morchellas might have been gathered within a radius 
of one hundred yards.” See Journal of Mycology, November 
1905-

Helen Sherman gives the “Host plants of Panaeolus epi- 
mvces Peck,” in the Journal of Mycology, July 1905, with a full 
page illustration, showing a well-developed plant attached to 
its host, a later stage of the same, also very young carpaphore.
