栖息在海绵上的真菌占据了一个生态位，由于其在生态学或制药学方面的潜力，最近引起了人们的极大关注。然而，人们对海绵和真菌之间的生态相互作用知之甚少。从地中海海绵Psammocinia sp.中分离出85个真菌类群。大多数（89%）的这些类群分离使用“样品压缩”的方法，结合使用杀菌剂修正的介质。发现了丰富的“陆生”分类群，如枝顶孢属、青霉属和木霉属，沿着可能未描述的茎点霉属和木霉属物种。这些分类群中的几个表现出体外抗真菌特性，确定对四个测试真菌。尽管在这项研究中分离出了大量的真菌类群，但我们估计与Psammocinia sp.相关的真菌多样性高于这里报道的。有人主张，Psammocinia，和其他海绵属，可能是一个主要的利基发现新的真菌物种，以及新的抗真菌化合物的真菌来源。
Fungi that inhabit marine sponges occupy an ecological niche that has recently attracted great attention due to the potential in either ecological or pharmaceutical advances. The ecological interaction between marine sponges and fungi is, however, only poorly understood. Eighty five fungal taxa were isolated from the marine sponge Psammocinia sp. from the Mediterranean Sea. The majority (89%) of these taxa were isolated using a `sample compressing` method, in combination with the use of fungicides-amended medium. Abundant `terrestrial` taxa such as Acremonium, Penicillium and Trichoderma were found along with potentially undescribed Phoma and Trichoderma species. Several of these taxa exhibited in vitro anti-fungal properties as determined against four test fungi. Even though a significant number of fungal taxa were isolated during this study, we estimate that the diversity of fungi that are associated with Psammocinia sp. is higher than reported here. It is advocated that Psammocinia, and other sponge genera, may be a prime niche for discovering new fungal species as well as novel anti-fungal compounds from fungal sources.
