Leucogyrophana pinastri is a species of fungus that belongs to the family Hygrophoraceae. It is a small to medium-sized fungus with a waxy cap that ranges in color from white to pale yellow or pinkish, typically 1-4 cm in diameter. The gills are decurrent, narrow, and crowded. In East and Central Texas, Leucogyrophana pinastri has been found growing on coniferous logs, stumps, and fallen branches, particularly on pine and cedar, often in moist, shaded areas. Fruitings typically occur from spring to fall, with peak activity during the summer months. The fungus is considered rare to uncommon in the region.

Spores (in KOH solution) of yellow merulioid fungus Leucogyrophana pinastri (Hydnomerulius pinastri) from a fallen oak (spore print olive brown) collected a day before in Sam Houston National Forest. Texas, February 20, 2023
Spores (in Melzer) of yellow merulioid fungus Leucogyrophana pinastri (Hydnomerulius pinastri) from a fallen oak (spore print olive brown) collected a day before in Sam Houston National Forest. Texas, February 20, 2023Observations of Leucogyrophana pinastri in East and Central Texas reveal the fungus grows on rotting wood, particularly pine and oak logs. The corticioid fungus exhibits merulioid pores and a wrinkled texture, with a yellow coloration. It was found on the underside of logs on Caney Creek Trail in Sam Houston National Forest, with fresh growth observed in December 2020 and recent growth noted in February 2023. The fungus has a distinctive margin area and produces olive brown spores. Microscopic examination of spores in KOH solution and Melzer's reagent confirmed the identity of Leucogyrophana pinastri. The observations suggest that the fungus is common in the region, thriving on decaying wood in forest environments. The consistent presence of the fungus in Sam Houston National Forest over time indicates its adaptability to the local ecosystem.
