Abstract: Investments of Agaricomycetes in morphological reproductive traits are constrained by a limited energy budget, as in any other fungal group. Such investments relate to fruit body size and number, and to spore size, the latter which is correlated with nutrient reserves. These ecological trade-offs are indicators of fungal lifestyles, for example ruderal vs competitive strategies. To shed some light on morphological trade-offs, we looked into pertinent correlations by comparing datasets about relative fruit body dry weights with fruit body and spore size, and fruit body number with fruit body size. In addition, we demonstrated how spore size translates to investments into nutrient reserves. We could confirm results from earlier studies which showed a positive correlation between fruit body and spore size, as well as a negative correlation between fruit body number and size. Finally, we found weak, but highly significant trade-offs between dry matter content of trama and total spore volume per hymenal area unit. In conclusion, we pointed to the fact that only considering reproductive morphological trade-offs would fall short of the complex morphological and physiological interrelationships in fungal individuals (genets). The need for further studies to gain a more comprehensive picture of input-output trade-offs would be the logical consequence.
