Nothopanus candidissimus is a species of fungus that belongs to the family Tricholomataceae. It is characterized by its small to medium-sized fruiting bodies with white to cream-colored caps and stems. In East and Central Texas, Nothopanus candidissimus has been found growing on decaying wood, particularly on oak and pine logs, in moist environments such as streamsides and woodland edges. The fungus typically fruits from spring to fall, producing clusters of tiny, white spores. Its mycelium is thought to play a role in decomposing organic matter and recycling nutrients in these ecosystems.
Observations of the fungus Nothopanus candidissimus in East and Central Texas reveal that it grows on the bark of trees, specifically hickory or possibly ash trees. On Caney Creek Trail in Sam Houston National Forest, north of Montgomery, Texas, the mushrooms were found two meters above the ground on May 31, 2020. Similar observations were made on the same trail, with the snowy oysterling mushrooms growing on tree bark. The species was identified as either Cheimonophyllum candidissimum or Nothopanus candidissimus, indicating some uncertainty in the classification. The sightings suggest that Nothopanus candidissimus prefers to grow on deciduous trees in forested areas of East and Central Texas. Further observations are needed to confirm the habitat preferences and distribution of this fungus in the region. The species appears to thrive in late spring.
