Cribraria cancellata is a species of slime mold that belongs to the phylum Mycetozoa. It is characterized by its distinctive network-like or reticulate pattern on the peridium, which is typically grayish-brown to dark brown in color. In East and Central Texas, Cribraria cancellata has been found growing on decaying logs, stumps, and other woody debris in moist, shaded areas, often in association with other slime molds and fungi. The species tends to fruit in the spring and fall, producing small, spherical to oval-shaped sporocarps that are typically 0.5-1.5 mm in diameter.

Sporangia of slime mold Cribraria cancellata (with x40 objective) from a thick wet pine log, collected in Sam Houston National Forest near Montgomery. Texas, November 24, 2023Observations of the species Cribraria cancellata in East and Central Texas reveal its presence on wet pine logs in the Sam Houston National Forest. On October 9, 2021, it was spotted on a wet pine log on Caney Creek Trail, with spore heads visible on both the log's surface and cut area. Close-up observations showed details of the slime mold's structure. Similar sightings occurred on November 24, 2023, on Sand Branch Loop Trail, where the slime mold was found on a thick wet pine log. Microscopic examination (x10 and x40 objectives) of collected samples confirmed the presence of sporangia, characteristic of Cribraria cancellata. These findings suggest that Cribraria cancellata is present in the region, thriving on moist pine substrates, particularly in areas with suitable humidity and substrate conditions. The species' occurrence was documented through photographic records and microscopic analysis.
