This paper summarizes the available data of Strobilomyces strobilaceus in Bulgaria. Review of the available previous records is made and numerous new findings are reported. Totally 30 localities of the species are currently known. An UTM-grid map is appended. The fungus appeared to be widespread, but not common and observations likely support its p...
The study is based mainly on an evaluation of literature records and some herbarium samples from the following institutions: GZU, National Museum of Natural History, Sofia, SO, SOMF, UPS. The first contribution on lichenized fungi was published by the Bulgarian botanist Sava Kazandzhiev in 1900. Later Atanas Popnikolov prepared six papers between t...

... The appearance of the catalogue in 2005 definitely stimulated research of both Bulgarian and foreign lichenologists on the study of lichenized fungi in Bulgaria. During this period, numerous papers, related to lichenized or lichenicolous fungi in Bulgaria, or taxonomic treatments citing specimens from Bulgaria have been published: Aguirre-Hudson et al.

... The checklist includes records on lichenized and lichenicolous fungi from 383 references and data from the public collections in Sofia and the university herbarium in Graz (GZU). Some taxa synonymized by Mayrhofer at al. (2005) are resurrected following recent taxonomic treatments. The bibliography includes fungistic papers as well as taxonomic treatments that cite specimens from Bulgaria. ...
... This species is characterized by very soft dark grey to black pyramidal and overlapping scales on the cap surface. In spite of the widespread occurrence throughout Europe, it is included in the National red lists of a number of countries (Assyov et al., 2011). ...
