Clarification of the Taxonomic Position of Paramecium caudatum Micronucleus Symbionts

The corticioid basidiomycete Jaapia ochroleuca (Bres.) Nannf. et J. Erikss. is recorded for the first time in the European Russia from the «Bryansky Les» Nature Reserve (Bryansk Region). The taxonomic position of the species is defined briefly. Its morphological description and data on distribution and ecology are provided. The details of microscopic structure of the collected specimen are illustrated.

Hyphal Apex

Thirty-one species of fungi (representing 13 orders) were examined for their ability to grow from a nutrient medium onto a non-nutrient medium; 17 were capable of colonizing the deficient medium, 10 were not, and 4 were indeterminate. The ability to grow onto deficient medium appeared to be related to the natural habitat of the fungus rather than to taxonomic position. Experiments with isotopically labelled nutrients showed that both colonizing fungi and non-colonizing fungi were capable of some transport of nutrients, the difference between the two groups being one of degree. In transporting fungi, labelled nutrients were moved more rapidly when the fungus colonized a deficient medium than when it colonized a nutrient medium; this suggested that movement of nutrients is adaptive to some extent. The importance of the growing hyphal apex as a sink for nutrients was demonstrated.
