Taxonomic notes

REFORMULATE…
Boletus comptus Simonini was described in 1992 with the collection of the holotypus found in the Roncolo park on calcareous soil under oak (Central Italy, region Emilia Romagna, province Reggio Emilia, locality Quattro Castella)


Why suggested for a Global Red List Assessment?


Geographic range

It is a species which mainly presents Mediterranean distribution, as recorded in Cyprus, Spain, France, Italy and Greece (Galli 1998, Muñoz 2005, Delivorias 2014, Loizides et al. 2019). However, it was latterly recorded in Iran (Seidmohammadi et al. 2017).
The species appears to display a narrower distribution compared to its potential geographic range.


Population and Trends

Suillellus comptus is a not common species, . After thirty years from its description few are the findings principally in Italy (30 localities and about 50 observations) and most observation cames from that region and Sardinia island. In addition to this only few countries reports the species: 6 localities in Cyprus, 1 in France, 2 in Greece, 1 in Iran and 1 in Spain.
Adjust numbers….Add a motiving sentence that it is a conspicous bolete lookad after to motivate the low total population estimate.

The “known” localities are about 0; ESTIMATE THE LIKELY TOTAL NO OF LOCALITIES The total population size is estimated to consist of 12.000 mature individuals deriving by 60 x 10 for potential unfound sites and 600 x 10 mature individuals per site and by estimating on average 2 genets /site (Dahlberg & Mueller, 2011).

Habitat and Ecology

S. comptus is an ectomychorrizal species in broadleaved woodland, that is significantly correlated with oaks (Q. alnifolia, Q. coccifera ssp. calliprinos, Q. frainetto, Q. ilex, Q. pubescens, Q. suber). It is found from near sea level up to low altitude areas, since it is recorded in sites ranging from 50- 1200 m ca, principally in the mediterranean.

Threats

Since Suillellus comptus is an ectomycorrhizal species, logging and wood harvesting consist a severe threat.
Moreover, the fragmentation of oak forests decreases climatic homeostasis and modify both biotic and abiotic conditions (Murcia 1995). Edge zones presents more extreme conditions (temperature, humidity, light), which in many cases become inappropriate for organisms adapted to forest interior (Renhorn et al. 1997; Rheault et al. 2003).
Furthermore habitat loss and degradation are also associated with the combined action of climate change and fungal pathogens in Mediterranean oak forests. The holm oak under water stress conditions is remarkably vulnerable to the fungal pathogens (e.x.Phytophthora quercina) (Praciak, et al. 2013, Durrant et al. 2016). Particularly severe periods of drought with increasing occurrence of dry years and the co-occurrence of pathogens,  may provoke a decline of oak forests. (Siwecki and Ufnalski, 1998)
