The paper presents 32 species of macrofungi new to the Kampinos National Park, found during the studies on fire-damaged areas after the forest fires in 2015. Three species new to Poland were described and illustrated (Calycellina leucella, Exobasidium juelianum, and Gymnopilus decipiens). Four species from Polish red list of macrofungi have been recorded in the Kampinos National Park for the first time: Botryobasidium vagum (R), Geastrum coronatum (V), Helicogloea farinacea (E), Inonotus cuticularis (R). During the current studies 17 pyrophilous species new to the Kampinos National Park were found.

Continuation of the mycological study of the fire-damaged pine forest in Kampinos National Park in central Poland in 2017 produced interesting new findings. Among the taxa collected, 36 were new to the park, six had not been hitherto reported from Poland (Calycellina araneocincta, Ciliolarina aff. laetifica, Clitocybe metachroides, Galerina cerina f. longicystis, Parasola cuniculorum, Pleonectria pinicola), and the previous status of one taxon (Pleonectria cucurbitula) had been uncertain. Short descriptions based on collected specimens have been prepared for all taxa new to Poland. The current number of taxa of macromycetes identified in Kampinos National Park has reached 1,604.

The Bieszczady Mts, a mountain range in SE Poland, is a hot spot of fungal richness and diversity in Poland. This paper summarizes 5 years of studies in the Bieszczady Mts, as well as previously published research. A total of 1,377 macromycetes taxa were found, including many (464) which were protected, red-listed, or very rare in Poland. Thirty-eight taxa (nine Ascomycota and 29 Basidiomycota) have been reported in Poland for the first time: <em>Agrocybe gibberosa</em>, <em>Auriporia aurulenta</em>, <em>Bolbitius variicolor</em>, <em>Bulgariella pulla</em>, <em>Chaetosphaerella phaeostroma</em>, <em>Clitocybe subspadicea</em>, <em>Clitopilus passeckerianus</em>, <em>Cortinarius anomalus</em> var. <em>subcaligatus</em>, <em>C. fervidus</em>, <em>C. flexipes</em> var. <em>inolens</em>, <em>C. sylvae-norvegicae</em>, <em>Cudoniella tenuispora</em>, <em>Entoloma bisporigerum</em>, <em>E. olorinum</em>, <em>E. poliopus</em> var. <em>parvisporigerum</em>, <em>E. sericeoides</em>, <em>Galerina caulocystidiata</em>, <em>Gymnopilus josserandii</em>, <em>Hymenoscyphus subferrugineus</em>, <em>Hypholoma olivaceotinctum</em>, <em>Inocybe queletii</em>, <em>Laccaria altaica</em>, <em>Lactarius romagnesii</em>, <em>L. rostratus</em>, <em>Mycena epipterygia</em> var. <em>atroviscosa</em>, <em>M. epipterygia</em> var. <em>candida</em>, <em>M. polygramma</em> f. <em>candida</em>, <em>Octavianina lutea</em>, <em>O. mutabilis</em>, <em>Pachyella violaceonigra</em>, <em>Panaeolus papilionaceus</em> var. <em>capitatocystis</em>, <em>Phaeocollybia jennyae</em>, <em>Psathyrella almerensis</em>, <em>Pyrenopeziza inornata</em>, <em>Scutellinia torrentis</em>, <em>Tricholoma basirubens</em>, <em>Tricholomopsis flammula</em>, and <em>Vibrissea decolorans</em>. For all new taxa, short descriptions based on the collected material have been provided.

The paper presents the results of several years of mycological studies carried out in Poland, in the Western Sudety Mountains (the Karkonosze, Kaczawskie, Izera, and Rudawy Janowickie mountains), Western Sudety Foothills (the Izerskie and Kaczawskie Foothills), and adjacent regions, such as the Jelenia Góra Valley, Lubawska Gate, and Sudety Foreland (the Niemczańsko-Strzelińskie Hills). During the study, the presence of 985 fungal taxa (species, varieties, and forms) was recorded; of these, 66 had hitherto not been observed in Poland.

This paper presents 18 species of fungi that are new to the Kampinos National Park and their buffer zone. Seventeen of these species were found during studies on wind-damaged areas after the forest was damaged in 2017. One species new to Poland has been described and illustrated ( Odonticium septocystidiatum ). A few of the species recorded ( Ciliolarina cfr. laricina , Daldinia petriniae , Pseudovalsa umbonata , Spongipellis litschaueri ) are very rare in Poland and hitherto mentioned from single localities in the country. Two species from the Polish red list of macrofungi were recorded in the Kampinos National Park for the first time – namely, Punctularia strigosozonata (E) and Trichaptum biforme (R). The current number of macromycete taxa known from Kampinos National Park has reached a total of 1,630.

The paper presents eleven species of fungi new to the Kampinos National Park. They were found during the studies on wind-damaged areas after the forest was damaged in 2017. Two species new to Poland were described and illustrated ( Nectria nigrescens and Strossmayeria basitricha ). The current number of macromycetes taxa known from the Kampinos National Park has reached 1,637.

We present interesting findings from the final year (2018) of the project concerning fungi in the fire-damaged forests in Kampinos National Park (central Poland). Seven taxa have been collected which are new to the park, one species (<em>Scutellinia patagonica</em>) hitherto unrecorded in Poland has been found. The current number of macromycetes taxa known from Kampinos National Park has reached 1,611.
