undescribed species outside of Europe, were found within L. albescens,
L. dispersa, L. hagenii and L. semipallida. Delimitation
of several putative taxa, e.g., L. crenulata and L. pruinosa,
and phylogenetic relationships among species are poorly supported,
therefore, future study should include more characters
and a more extensive taxon sampling. Project supported by

Bolivia constitutes an important world centre of biodiversity
owing to its location in the tropical zone and to the diverse
topography of the area (Andes and Amazon lowlands occur
here). At the same time, the country belongs to that group of
South American countries in which lichen biota is the least
investigated. Only 550 species are known in the country so far.
In the years 2004–2007 lichenological studies were carried
out in Bolivia that were concentrated mainly in the Madidi
region. The field studies included the following montane and
lowlands ecosystems: various types of humid, seasonal and
dry forests, savannas and high montane grasslands – puna. As
a result of the survey a rich collection was gathered representing
lichens of all ecological groups. Preliminary results of the
study indicate high diversity of lichen species in the studied
areas, including new records for the country. Among others,
these 2 species are new to Bolivia – Icmadophila adversum
and Piccolia conspersa and they were recognized and are presented.
Currently, the project aimed at inventory of lichens
and lichenicolous fungi in the Madidi region (the complex of
three protected areas – Madidi, Apolobamba and Pilón Lajas)
is under preparation. The lichen inventory will be preceded by
a detailed analysis of taxonomic diversity and distribution of
lichens in the study area. The project will be conducted in collaboration
with Polish and foreign lichenologists working on
various groups of lichens, and botanists conducting advanced
studies in the Madidi region at present.

Extensive investigations of the lichen biota in Lublin were first
conducted by J.Rydzak over 50 years ago (1953). Since that
Lichenology
time, the area of the city has increased considerably, from 30
to 147 km 2 . The urban housing layout as well as air, and sanitary
conditions have all changed. Nowadays, two forest complexes
and a large artificial water reservoir built in the 1970s
lie within the city limits. The present study of lichens was carried
out in 98 localities in 2006– 2010. Compared to Rydzak’s
observations, we can now see a distinct decrease in the abundance
of the epiphytic lichen biota; from 55 to 40 species. This
is especially alarming when one considers the fact that the city
area has increased markedly. There were 19 species reported
in the 1950s which have not been found now. The most commonly
occurring species nowadays is Phaeophyscia orbicularis.
It is found in 36 localities. A similar abundance was also
observed in Physcia dubia, and in Xanthoria parietina; both
species were present in 35 localities. In recent years, the once
deserted lichen areas have begun to show some new appearances.
Lichen was observed in the city centre. Nowadays, 46
species of epilitic lichens have been reported: the number is
11 more than in the 1950s, although 16 species have not been
found. Of the species that have been reported from Lublin for
the first time, the most noteworthy are: Mycobilimbia tetramera,
Aspicilia calcarea and Lecanora polytropa. Interestingly,
species that typically grow on trees (Pseudevernia furfuracea,
Melanelia exasperatula, Physcia stellaris) were observed on
bedrock.

Prof. Roman Kobendza strictly protected area “Sieraków” was
established in 1937 as a nature reserve. In 1959 it was transformed
into the strictly protected area lying within Kampinos
National Park. It is 1204.91 ha. in area. It includes classic parabolic
dunes, a swamp valley named “Cichowąż” and a flow valley
called “Młyniska”. It is characterized by a great diversity
of plant communities, including mixed forests, moist coniferous
forests, alder swamps, mixed alder-ash, and oak-hornbeam
forests. A characteristic feature of this area is the presence of
a large area of old-grown forests. From 2009– 2010 an inventory
of lichen within the strictly protected area of Sieraków, was
made. The result was the finding of many rare and protected
species of lichens. At the same time a list of species occuring in
this area was drawn up.
