September 18 - The fungi inventory in Polistovsky Reserve. Part II.

In early September, a study of the fungi in Polistovsky Reserve was continued, the work was conducted under the guidance of a mycologist from Moscow Evgenia Pravdolubova. That time, two routes were planned in Loknyansky district.

The first route coincides with the ecological path "The way of mosses", excursions on which are available for tourists. Most often, on a route passing through a birch forest, a marsh and an old aspen forest, there were fly agarics, first of all, Amanita rubescens and a poisonous Amanita citrina.

There were a lot of Cortinarius armillatus. On logs of the late stages of decomposition, a variety of Plutea grew, mostly plain-looking mushrooms with a brown hat, but among them were beautiful bright yellow ones. Further work is to determine their exact form: Pluteus leoninus or Pluteus chrysophaeus.

Polypores of that forest, not so old, were not as varied as at the previous examined spot. The predominants were Fomes fomentarius, Piptoporus betulinus and Phellinus igniarius, once researcer met Inonotus obliquus. It is interesting that polypore which is common in the cities - Schizophyllum commune - on all four routes in Polistovsky Reserve was noted only once, at the entrance to "The way of mosses" trail.

The second planned route lay on Dubovets island, the path to which was complicated by the overcoming of a large beaver dam of recent years. Despite the difficulties in the way, the expert was pleased with the finding of several species that did not occur on other routes, for example, a fungus growing on fallen leaves with a wonderful fluffy foot, previously identified as Gymnopus peronatus.

On the swamp there was also a lot of interesting things. On the part of the way, Leccinium holopus with their white hats were constantly encountered, and there was found a unique lichen Lichenomphalia umbellifera. Most fungi that make symbiotic cointeraction with algae and form lichens belong to Ascomycota. Among Basidiomycota, to which Omphalina belongs, the ability to form lichens is an exception.

Intensive work continued after the passage of the routes: the mushrooms had to be described, photographed, preparations of the plates examined with a microscope, and some mushrooms are to be even tasted! The description of taste and smell is required as a part of definition of Russula and Lactaria species.

The first stage of the fungi inventory in Polistovsky Reserve is over. According to its results the scientific report and a list of marked species will be compiled. In the future, the study is planned to continue and expand.
