This always grows with

This always grows with Suillus bovinus so there should have been some of those closeby.

They are part of the Boletus

They are part of the Boletus family but I don't know whether they just grow close to B bovinus because they both like the same conditions and are pine associates or if they interact with each other in some way.

Abstract

Many intimate associations between different species of ectomycorrhizal fungi are inferred on the basis of the consistent co-occurrence of their fruit bodies. Suillus bovinus and Gomphidius roseus, where the latter never occurs without the former, is one example. This association was examined with PCR identification and light microscopy. S. bovinus and G. roseus were unambiguously separated on the basis of RFLPs of the PCR-amplified ITS region of ribosomal DNA. Tuberculate mycorrhizas of Pinus sylvestris sampled under fruit bodies of G. roseus and S. bovinus were investigated and the majority were identified as mixed associations involving both G. roseus and S. bovinus. Tuberculate mycorrhizas, which macroscopically resemble the ones of Suillus species, contained typical chlamydospores of G. roseus and they had haustoria where G. roseus hyphae penetrated the cortical root cells. Pine seedlings collected near the fruit bodies of the two species were mainly colonised by S. bovinus. Mycelial rhizomorphs collected under the fruit bodies of G. roseus were identified as S. bovinus, while both fungal species were present at the base of G. roseus fruit bodies. The significance of these observations and the possibility that G. roseus acts as a parasite are discussed.
