Three Fungi Imperfecti. J.S. Bayliss Elliott and H.C.Chance 49 
Phomopsis Tulasnei on the stems of the Maple has pycnidia, 
and Gloeosporium acerinum, which is the same fungus growing 
on the leaves, is without them. 
Another fungus proved to be Naemospora Strobi Allescher*, 
which has not hitherto been recorded for the British Isles: this 
fungus we had also found two months previously growing 
similarly on Pinus sylvestris twigs in Pool Hollies Wood, Sutton 
Park (Warwick). 
NAEMOSPORA STROBI Allesch. 
The spores are contained in irregularly shaped cavities more 
or less fused at maturity, formed under the periderm, the walls 
having a yellowish tinge; the spores are of two forms, sausage- 
shaped with a slight depression, 3-4 x 1-5-2 w, and rod-shaped, 
3-4 X I-24, unicellular, hyaline, numerous; when mature they 
are exuded in mucus from irregular, somewhat rounded, slits 
in the bark, and form cream-coloured tendrils; sporophores 
straight and pointed, fasciculate in bundles of 3-6. 
In Allescher’s description of this fungus only one kind of 
spore is mentioned—the rod-shaped, the form which we find 
only in very mature specimens. 
This possession of two kinds of spores, or of spores which 
assume different shapes, is a common feature in quite a large 
number of these Fungi Imperfect. 
The third fungus was Fusicoccum bacillare S. and P., but this 
specimen differed from that described by Allescher} in having 
no white disc and larger spores (17-20 x 34); it is interesting 
as forming a transition between the two varieties Fusicoccum 
bacillare var. dolosa and F. bacillare var. acuwm: it resembles 
the former in having no white disc and the latter in possessing 
larger spores. 
Fusicoccum bacillare grows on the bark of Pinus sylvestris, 
but the variety acuum grows on the leaves, so that this fungus, 
like Cytotriplospora Pini, bears out the theory that is now be- 
coming generally accepted, that the same fungus may occur on 
the stems and leaves of the same plant, and yet have a some- 
what different form on the leaf from that on the stem. 
We wish to take this opportunity of thanking Mr W. B. Grove 
for his kind help in the identification of these species.
