Friesia X, 4-5

This species is the marine fungus most frequently found at Grønhøj.
It is common on driftwood on the upper beach, at the base of
the dunes and in the gullies. Fruit bodies, often gregarious, are clearly
seen with the naked eye from a distance of 2 metres (Fig. 13).
The closely related species, C. cristata, is characterized according
to KOHLMEYER (1960) by having 3 septa and shorter spores than C.
comata. A collection with these characters was found by the present
author at Grønhøj on 30.3.70. The triseptate spores measured 28-32 X
8-11;li and were thus significantly shorter and smaller than the
5-sept at e C. comata spores. Ho wever, these spores appear to be toa
narrow in comp arison with the illust rat ions of the type material of
C. cristata. The lateral slime appendages were 16-20 ;li in length. The
perithecia grew in close association with perithecia of the typical
C. comata and were partly free on the wood surface, partly immersed.
KOHLME YER (1963) mentioned a find with similar characteristics
which he referred to C. cristata. Whether C. cristata is a true species
or simply a retarded developmental stage of the extremely variable
C. comata can perhaps be determined by growth trials.
