Assessment Notes

Justification

Dentipellopsis dacrydiicola is a resupinate hydnoid fungi found in Hainan Province, China. It was described in 2013 and has not been documented in the literature since. If Dacrydium pectinatum is confirmed as its only host, as it is a threatened tree, Dentipellopsis dacrydiicola may qualify for a threatened category, but more search efforts and information on its habitat preferences are needed to estimate the population size and full distribution. For now the species is assessed as Data Deficient (DD).

Taxonomic notes

The genus was established based on the morphological characteristics of this species and phylogenetic analysis. It belongs to the Russalales order, but the position at family level is not yet clear (Zhou and Dai 2013).

---

Geographic range

This species was described from the Bawangling Nature Reserve in Hainan province of China.

---

Population and Trends

Dentipellopsis dacrydiicola has only been documented once, in one site. More information and search efforts are needed to determine whether the population size is truly small, and with a restricted distribution, or if the species has been overlooked.

Population Trend: Unknown

Habitat and Ecology

Dentipellopsis dacrydiicola is a resupinate and annual fungus that grows on rotting wood. It was found in the Bawangling National Nature Reserve, which harbours tropical rainforest. Zhou and Dai (2013) stated that the type specimens grew on wood of Dacrydium pierrei (=Dacrydium elatum), but the tree is not described for Hainan. Records from this region are usually attributed to Dacrydium pectinatum instead (Thomas 2013).

---

Threats

It is possible that this fungus was found growing on rotting wood of Dacrydium pectinatum, which has been assessed as Endangered (Luscombe et al. 2013). If it is established that Dentipellopsis dacrydiicola grows exclusively on this tree, habitat declines could be impacting this species, but more information is needed.

---

Conservation Actions

Specimens were found in the Bawangling National Nature Reserve. Given that there is just one record, search efforts are needed to establish whether this species has been overlooked or if it is potentially rare. More information on habitat preferences is also needed to help establish its full distribution and possible threats.
