Lycoperdia X. Yang & C. L. Zhao gen. nov.

Type species.

Lycoperdia tomentosa X. Yang & C. L. Zhao

Etymology.

Lycoperdia (Lat.) refers to the new genus resembling Lycoperdon in basidiome morphology.

Description.

Basidiomes pyriform and subglobose to globose when dry. Exoperidium with densely arranged tomentose structures. Endoperidium papery and fragile. Gleba with cottony texture when dry. Exoperidium made up of chains of inflated cells, ellipsoid, oblong, pyriform, thin-walled to slightly thick-walled, smooth, colorless hyphae in 5 % KOH. Endoperidium made up of colorless hyphae, thick-walled, occasionally branched, no septa. Capillitium of Lycoperdon - type, branched, thick-walled, no septa. Paracapillitium composed of chains of colorless, inflated cells, branched, no septa. Basidiospores globose to subglobose, with distinct spines, with a short pedicel.

Notes.

In our phylogenetic analyses (Fig. 1 ), Lycoperdia is identified as a monophyletic group, typified by L. tomentosa . The new genus Lycoperdia falls within the family Lycoperdaceae ( Agaricales ) and is closely related to Calvatia . However, Calvatia is distinguished from Lycoperdia by its dehiscence of peridium, which occurs by irregular fragmentation, and Calvatia - type capillitium ( Larsson and Jeppson 2008; Li et al. 2024).
