Assessment Notes


Neoburgoa freyi has been recorded from several localities and is hypothesized to be widespread within its host range. it has been described to be found growing on three different hosts all of which are not threatened and widely distributed. There is no current data on population decline or threats. We recommend this species be listed as least concern (LC).

Taxonomic notes

Why suggested for a Global Red List Assessment?

EDGE Species

Geographic range

This species is known from multiple localities in the alpines in Switzerland (Lawrey et al, 2016) and Austria (Berger & Zimmerman, 2022). It is very likely this species is widespread in the Alps (Lawrey et al, 2016). Zhurbenko & Pino-Bodas detected this species in the Russian Arctic, as well (Berger & Zimmerman, 2022).

Population and Trends

There is no current information on population size of this species, but it has been recorded from 14 localities in the alpines growing on Cladonia rangiferina (Lawrey et al, 2016), Cladonia stellaris, and Cetraria nivalis (Berger & Zimmerman, 2022) which are all widespread. It is suspected this species is widespread within its host range.

Population Trend: Uncertain

Habitat and Ecology

This species is known from the thalli of its host. There has been no visible damage or interaction with the thalli observed indicating the host and species have likely evolved together for a long period (Lawrey et al, 2016). Additionally, this may be indicative that N. freyi

is confined to theses host genus of species (Lawrey et al, 2016). This species is characterized by conspicuous yellow to orange bulbils growing on its host lichen (Berger & ZImmerman, 2022) with no observed mycelium (Lawrey et al, 2016).
