What does the published scientific research say about Scleroderma geaster?

Scleroderma geaster — also described in peer-reviewed literature as Dentiscutata heterogama and previously as Gigaspora geterogama — is an arbuscular mycorrhizal fungus (AMF) with 8 PubMed records referencing it in plant-input contexts. Researchers searching for Scleroderma geaster scientific research or Dentiscutata heterogama mycorrhizal inoculum will find it appearing across studies spanning inoculum production, field ecology, and multi-species AMF trials.

Inoculum production research (PMID 25763020) reported that Tropstrato substrate inhibited sporulation of Dentiscutata heterogama, a substrate-sensitivity finding relevant to producers evaluating organic carrier compatibility. Separately, a Brazilian Seasonal Dry Forest study (PMID 37507826) found Dentiscutata heterogama's presence strongly correlated with the rhizosphere of the endemic legume Mimosa tenuiflora, suggesting a host-specific ecological association in semi-arid conditions.
