New Pine-Forest Fungi Expand Wood-Inhabiting Diversity

In MycoKeys volume 137 (pages 273–297) DOI 10.3897/mycokeys.137.203862, Kai-Yue Luo and colleagues reported the discovery of three new fungal species inhabiting Chinese pine trees, specifically Pinus massoniana. The publication appears on ¹

The newly described taxa belong to two distinct orders. Botryobasidium massonianae is a member of Cantharellales; it displays fluffy, pellicular basidiomata with a hypochnoid hymenophoral surface and generative hyphae that are simple septate. Its basidia bear four to six sterigmata, while its basidiospores measure 6.3–9.2 × 2.8–3.9 µm ².net].

Peniophorella crassibasidiata falls under Hymenochaetales. This species features soft, coriaceous basidiomata and thick-walled generative hyphae. Three types of cystidia are present, and its cylindrical basidiospores range from 8.4–12.4 × 3.1–4.2 µm ².net].

Also in Hymenochaetales, Peniophorella variegata presents farinaceous basidiomata with a smooth hymenophoral surface. It contains three cystidian types, hyphidia, and basidiospores measuring 7.9–10.8 × 3.9–5.1 µm ².net].

Phylogenetic analyses using a combined ITS+nLSU dataset were performed via Maximum Likelihood and Bayesian Inference methods, confirming the placement of Botryobasidium within Cantharellales and the two Peniophorella species within Hymenochaetales ².net].

These findings underscore how much remains to learn about fungi that live inside wood. Similar discoveries have been made for long‑known pine-inhabiting taxa such as Phellinus weirii (1952) and Armillaria solidipes (1870), illustrating ongoing exploration of fungal biodiversity worldwide.

For mushroom foragers, recognizing these taxa is valuable because many wood‑inhabiting fungi are either edible or provide cues about forest conditions. Detailed morphological descriptions—such as the presence of hypochnoid hymenophores in B. massonianae or the cystidian diversity in Peniophorella spp.—offer practical keys for field identification when surveying pine stands.

Further surveys across different pine habitats could reveal additional hidden diversity, reinforcing the importance of detailed taxonomic work for both science and responsible foraging.
