โœฆ Synopsis

Selective isolation procedures were carried out on decaying leaves of Nymphoidespeltata (Gruel.) O. Kuntze in order to study the pythiaceous fungi (Peronosporales) associated with the decomposition processes. In addition to Pythium marsipium Drechsler and P. plerotieum T. Ito, a number of Pythium species were isolated with filamentous non-swollen sporangia. Under special culture conditions (in water under a day/night rhythm) sexual reproductive structures of P. diclinum Tokunaga and P. apleroticum Tokunaga were also obtained. However, several isolates designated as Pythium 'F', remained sterile. Within this group three types could be distinguished according to their temperaturegrowth relationships. As the species recorded have been found very rarely and only one was represented in the CBS collection, detailed descriptions with short discussions are presented.

Fungi potentially able to decompose cellulose, in the tidal mud-flats of Kuwait, have been investigated. More than 58 species were isolated and their cellulytic ability were tested. Many of the species recorded are well known cellulose decomposers, while for many others the strong cellulytic activit
