In addit ion t o the species of Ascomycetes and B asi dio m y cet es
listed, several members of the Fung i imperfec ti were also collect ed at
the Gr ønh øj locality. Among the most frequent were H elic oma maritimum
LINDER (Fig.9u) and Pi r icauda pelagica JOHNSON (Fig. 9v).
Both species generally occur on t he unde rside of wood which has
remained undisturbed under moist conditions at the base of the dune
for some time. Many collect ions, chiefly of the genera L epiosphaerui,
Lulworthia and Pleospora , still remain to be treated.
THE FREQUENCY OF THE F UNGI
AT GR0NH0J, JUTLAND
On the basis of the number of collections bearing fruit bodies, the
frequency distribution of the marine fungi identified is shown in
Table L
Since the majority of collections were made at Grønhøj, the fungi
from this locality are listed separately. Corollospora comata is clearly
that marine ascomycete most frequently found. It is moderately conspicuous
due to the approx. 0.5 mm large, dark fruit bodies on the
surface of the often faded wood (Fig. 13). C. tubulata and Amylocarpus
encephalouies, however, are of a more infrequent occurrence than
would appear from Table 1. The large number of collections recorded
of these two species is partly due to their large fruit bodies. The
perithecia of Corollospora tubulata are about 0.5 mm in diameter and
are conspicuous in the white sand, while Amylocarpus encephaloides
bears perithecia of up to 3 mm in diameter. When present, these two
species are almost certainly recorded. Corollospora maritima, with fruit
bodies of only approximately 0.25 mm, is easily overlooked (Fig. 5).
This species often grows in association with C. t rifurcata and should
be ranked after C. comata. In investigations of spores in skum from
sand coasts (North Carolina, Georgia, Tenerife), KOHLMEYER (1966)
