Leucogaster solidus L. Fan & T. Li View in CoL sp. nov. ( Fig. 2 View FIGURE 2 )

MycoBank:—MB 839331

Diagnosis:—Basidiome brown to reddish brown, verrucose, gleba non-gelatinous, peridium (90–)110–250 μm thick, trama 20–42.5 μm thick, basidiospores large, globose to subglobose with alveolate ornamentation.

Etymology:— solidus , refers to the solid and non-gelatinous gleba when fresh.

Holotype:— CHINA. Yunnan Province, Kunming City, in soil under mixed woodlands, dominated by Pinus armandii , 28 December 2012, collected by L. Fan and J. Z. Cao ( BJTC FAN733 About FAN , ITS = MW 938546 View Materials ).

Description:— Basidiome hypogeous, subglobose to globose, 0.7–0.9 cm diam, brown to reddish brown when fresh, dark blackish brown to fuscous red when dry, surface verrucose, with a shallow depression at the base. Peridium (90–)110–250 μm thick, reddish brown, composed of interwoven hyphae, hyphae hyaline, 1–1.5 μm broad, not inflated, turning pink in 3% KOH, tissue near surface obscured by red pigment that forms red to dark red “pigment balls” in Melzer’s reagent. Gleba solid, whitish when fresh, light yellow-brown when dry, loculate, locules vary in size, fine alveolate-reticulate, non-gelatinous when fresh, not exuding sticky latex when damaged. Trama thin, 20–42.5 μm thick, composed of hyphae of 2.5–3.5 μm broad, hyphae hyaline, thin-walled, septa. Hymenium absent. Basidia not seen.

Basidiospores globose to subglobose, colorless, [30/1/1] 12–14(–16) × 11–14 μm, Q(L/I) = 1.01–1.18, Q m = 1.07 ± 0.05, including ornamentation of less than 0.5 μm high, consisting of an irregular alveolate reticulum formed by anastomosed ridges, gelatinous perisporium absent, hilar appendix or sterigmal scars not found.

Habit, habitat and distribution:—hypogeous, in the soil under mixed forest, dominated by Pinus armandii Franch. , Yunnan Province, China.
