Basidiomata depressed globose, subglobose to pyriform, growing on decaying wood. Subgleba reduced (< 1/3 of basidiome) composed of compacted cells. Exoperidium minute warts or spines (<0.5 mm in long.), persistent, brown to dark brown with age. Endoperidium surface smooth, cream. Gleba powdery, brown.Exoperidium base like the apex, composed of chains of
sphaerocysts (like in L. perlatum) that are globose, subglobose, ellipsoid, with truncate apices, except at the top of the chain, where they are pyriform. Endoperidium composed of interwoven hyphae that are hyaline and with wall <0.5 μm. Mycosclerids and inflated terminations absent. Capillitium absent. Paracapillitium abundant. Basidiospores globose, 4.5–7 μm, strongly verrucose in LM, aculeate in SEM; spines 0.5–1.7 μm long; the density of ornamentation 7–16 warts by a reduced area of 10 μm.

Dring, Feddes Repert. 74:113 (1967).

Due to the several records in the Neotropics, we suggest this species to be categorized as Least Concern (LC).
Known from tropical and subtropical America (13 countries).
There are 393 records of this species in GBIF (as Morganella fuliginea), most of them from Brazil (180) and Costa Rica (146).
Population Trend: Uncertain
Common in Brazil, found on rotting wood. In Brazil, the species is found in Atlantic Forest, Amazon Forest, Caatinga and Cerrado.
In Brazil, this species is well distributed. However, it is found in the Atlantic Forest, a hotspot, in the Amazonia (currently being deforested at the highest rates in the last decades) and Cerrado (also a hotspot). Also, Caatinga is threatened with desertification.
Reports in Brazil are from protected and unprotected area.
We need more collections in herbaria and better taxonomic understanding - many collections are misidentified as Lycoperdon (=Morganella) fuliginea, but correspond to different species.
