Pvzd. Kaip atskirti Phlegmacium nuo Thaxterogaster:
Phlegmacium
Currently included subgenera: Phlegmacium, Bulbopodium, Carbonella and Cyanicium
Description: Basidiomata medium- to large-sized, rarely small, agaricoid (phlegmacioid, rarely telamonioid), some
species sequestrate, development type stipitocarpic or pileocarpic.
Pileus (1–)3–12(–20) cm, at first hemispherical to convex, low convex to almost plane when old, rarely with a
broad umbo; surface in some species innately fibrillose or radially wrinkled, rarely scaly or with patches of veil; from white, pale ochraceous and yellow to dark brown and umber
with yellow, orange, red, greyish, greenish or purplish tints, in some species completely purple; dry, viscid or glutinous.
Lamellae in the vast majority of species crowded, in some species medium spaced, emarginate, at first pale greyish
white to purple, later pale brown to purplish brown, darker in the species of subgenus Carbonella. Stipe 3–13(–20) cm long, (0.4–)0.8–2(–3) cm wide at the apex, up to 5 cm at
base, clavate to bulbous with a rounded or a marginate bulb, or cylindrical to rooting, in the vast majority of the species
more or less white, sometimes with purplish tints, in some species grey, dry. Universal veil white, grey, yellow, greenish yellow, more or less brown or purple, sparse to abundant,
forming incomplete and complete girdles on the stipe. Context in many species in pileus and stipe white, sometimes with purplish colours, in some species grey, yellow-greenish, olive-grey, pale greyish purple to vinaceous brown, in the species of subgenus Cyanicium becoming vinaceous red on exposure. Odour in lamellae indistinct or in some species raphanoid, earthy, grassy, rubbery, sweetish, fruity or farinaceous. KOH reaction in pileus context negative, yellow,
orange, reddish lilac, olivaceous or pale brown. Basidiospores 7–12.5(–17) × 4–8.5(–10) μm, amygdaloid, ellipsoid
or citriform, in some species subglobose, finely to strongly verrucose. Pileipellis duplex, simplex in P. subgen. Cyanicium and some lineages of P. subgen. Phlegmacium, epicutis
in many species ± gelatinous.
Ecology and Distribution: In the Northern Hemisphere with the species of Fagales, Pinaceae and Tilia.
Thaxterogaster
Currently included subgenera: Thaxterogaster, Cretaces, Multiformes, Riederorum, Scauri, and Variegati
Basidiomata small- to large-sized, agaricoid (phlegmacioid, myxacioid) or sequestrate, development type stipitocarpic to pileocarpic. Pileus 1–12 cm, at first hemispherical,
then convex to plano-convex; surface smooth, innately fibrillose or somewhat scaly; ± white, ± yellow, pale to dark brown with greyish, ochraceous or reddish tints,
umber to blackish, ± purple or with a purplish tint, some species with olivaceous colours; dry, viscid or glutinous, with hygrophanous spots or streaks or non-hygrophanous.
Lamellae crowded to medium spaced, adnate, adnexed or emarginate; when young white, pale grey, pale brown, green, ± purple or with a purplish tint. Stipe 4–13 cm long,
0.3–2.5 cm wide at the apex, up to 5 cm at the base; cylindrical, clavate, rooting or bulbous, bulb rounded to ± marginate; white, pale brown, ± purple, some species with greenish
colours, in species of sect. Purpurascentes usually turning deeper purple when bruised, dry. Universal veil white, purplish white, purple, in some species turning pink; sparse
to more abundant, in pileocarpic species at the bulb margin and pileus margin, in stipitocarpic species forming a thin sock-like sheet or incomplete and complete girdles on
the stipe, usually dry but in some species viscid. Context in pileus white, pale brown, purple or dark blue/blackish green, in stipe white, ± yellow, pale brown, ± purple or with
purplish or green/olivaceous colours. Odour in lamellae indistinct, in the context of the stipe indistinct, honey-like or sweet, garlic-like in T. crypticus. KOH reaction negative
or red in pileus, context and/or stipital veil. Basidiospores 6–18 × 3.5–9 μm, subglobose, amygdaloid, fusoid to ellipsoid, finely to strongly verrucose (subglobose, smooth and
very large in T. crypticus 25–35 μm in diam.). Cystidia absent. Pileipellis duplex, hypoderm present.
Ecology and Distribution: In the Northern Hemisphere with species of Fagaceae, Betulaceae, Tilia and Pinaceae
