Why suggested for a Global Red List Assessment?

Boletus ichnusanus is a rare species with fragmented distribution limited to some southern countries in Europe. The species has a restricted range and grow in small scattered localities,  presents strong fluctuations in fructification. Major treats are habitat loss and degradation due to change of management regime.


Geographic range

It has been noted mainly in European countries, predominantly in the Mediterranean Region, such as in Bulgaria (Assyov and Stoykov 2011), France (Chevtzoff 1998; Redeuilh and Simonini 1999; Eyssartier and Roux 2011), Greece, as well as the Cyclades Islands (Constantinidis 2009; Polemis et al. 2012), Italy (see above), Spain, including the Balearic Islands (Águeda et al. 2006; Ruiz Fernández and Ruiz Pastor 2006; Calzada Domínguez 2007; Muñoz et al. 2008), one record in Austria (AMS 2009), one locality in Portugal, in Macedonia in Quercetum frainetto-cerris (Karadelev & Rusevska, 2016)


Population and Trends

Population Trend:


Habitat and Ecology

Thermophilous broadleaved forests, on poor dry soils, also in grassy soil, margins of the woods, under Quercus spp. (Q. cerris L., Q. coccifera L., Q. frainetto Ten., Q. faginea, Q. ilex L., Q. petraea (Matt.) Liebl., Q. pubescens Willd., Q. pyrenaica Willd., Q. robur L., Q. suber L.) and to a lesser extent Cistus spp., rarely with Castanea sativa Mill. and near to the exotic Eucalyptus camaldulensis Dehnh. (Gelardi et al., 2015), maybe in Populus and Salix woods (Karadelev & Rusevska, 2016) also found with Pteridium aquilinum (L.) Kuhn (Tentori 2006). It grows in small scattered localities. It’s a thermophilous and xerophilous species, growing during warm and dry years and therefore fluctating in fructification; in Portugal with Quercus faginea on calcareous soils

Temperate ForestSubtropical/Tropical Dry Forest

Threats

The following observations came from Italy:
6.1 Recreational Activities and 6.3 Work & Other Activities: People spending time in nature could represent a threat, given the very low number of mature individuals (usually only 1-4) in each population.
7.1.1 Increase in Fire Frequency/Intensity: The populations growing in Mediterranean climate are endangered by increase of fire frequency and intensity.
7.2.3 Abstraction of Surface Water (agricultural use): Some sites of occurrence of the species are near farmlands, where the abstraction of surface water for agricultural use could be a threat.
7.3 Other Ecosystem Modifications: habitat loss and degradation due to change of management regime.
In Portugal outside of Natura 2000 network of protected sites.
In Austria only one record in 1995.

Conservation Actions

Conservation actions: Alessioporus ichnusanus is unprotected by international, national, and regional laws.
Conservation actions needed: Collecting more information on ecology and distribution. The presence of the species in areas subjected to protection such as parks and nature reserves allows, even in the absence of specific conservation actions for the fungus, the activation of appropriate preservation strategies related to the protection of habitats. Ex situ conservation (preservation and maintenance of fungal genetic resources in pure culture) may also be of great importance.
