Abstract:

Comparative studies of the effect of nutrients, salinity, temperature, and other factors on reproduction in various marine Ascomycetes have demonstrated noteworthy physiological dissimilarities between lignicolous and foliicolous species. Specific differences are noted among isolates in utilization of various carbohydrates for maturation of perithecia. Cellulose is an effective carbon source for reproduction by all of the fungi. The foliicolous species, Lindra thafassiae, is unable to utilize wood for reproduction but forms large numbers of mature perithecia on leaves of Thalassia. Species of the scolecosporous genera, Lulworthia and Lindra, exhibit limited reproduction at salinities below 20 per cent seawater in contrast with the euryhaline characteristics of Halosphaeria mediosetigera. Different temperature optima of possible ecological significance are noted for maximal development of fruiting structures.
