Abstract: Lepiota jacobi Vellinga& Knudsen, a species newto East Asia, is reported and illustrated . It is characterizedby its
small spores, theabsenceof cystidium, andthemore or less acute spines on pileusmade up of inflated cells in short chains .
Key words: Lepiota jacobi ; New record; East Asia
Lepiota (Pers .: Fr .) S . F . Gray is one of themost com-
mongenera in Agaricaceae, Agaricales, basidiomycetes . Update,
nearly 70 species have been reported in East Asia ( Bi et al .
1990 , 1994; Chiu, 1948; Hongo, 1986; Imai , 1938 , 1939; Ito,
1959; Li et al . 1993; Mao, 1998; Teng, 1936 , 1939 , 1996;
Wang, 2004; Wang and Yang, 2005a, b; Yang, 1990; Yang et
al . 2005; Yuan, 1995) . L. jacobi Vellinga& Knudsen is report-
ed and illustrated fromEast Asia for the first time herein . In the
description, macro-morphology is basedonthefield notes and col-
or slides of thematerial; micro-morphology is basedon observation
of the material under microscope . For microscopic studies, 5%
KOH was used as mounting medium to rehydrate the tissue . For
the size of the basidiospore, the apiculus is not included . The
abbreviation n?m?p means n basidiospores measured from m ba-
sidiomata of p collections . The notationof theformb-cstands for
the dimensions of the basidiospores . Q is used to mean“length?
width ratio”of a basidiospore in side view; Q means average Q
of all basidiospores±sample standard deviation .

Basidioma (Fig . 1 : 1 ) small-sized . Pileus 55 mm in di-

beige to whitish, covered with small discrete, grey to dark
brown, acute spines up to 1 mm high and less 1 mmwide at the
base, towards margin spines more or less concentrically arranged
and slightly bigger and more adnateand fibrillose; marginof pile-
us undulating, with remnants of annulus . Lamellaefree, crowded,
whitish . Stipe 55×9 mm, cylindrical, slightly broadened towards
base, hollow, with superior annular zone, pale pinkish abovean-
nular zone, sometimes with orange-ting, fibrillose-flocculose,
below annular zone with girdles andzonesof woolly, brown squa-
mules on paler background . Context whitish to white .

1 . Basidioma; 2 . Basidiospores; 3 . Structure of spines on pileus
view, dextrinoid, not metachromatic inCresyl Blue, often in tet-
rads . Basidia 13 - 18×4 - 5.5μm, narrowly clavate, sometimes
cylindrical, 4-spored . Lamellae edge fertile . Cheilocystidium
and Pleurocystidiumabsent . Spines on pileus (Fig . 1 : 3) made
upof more or less regular chains of inflated elements: terminal
elements subglobose, pyriform, ellipsoid or subclavate, 21 - 81
×11 - 31μm, with brownish and thickened walls; intermediate
elementssomewhat inflated to cylindrical, 8 - 18μm wide, with
brown walls; basal elements cylindrical toslightly inflated, 4 - 10
μmwide, with brown, non-encrusted walls . Clamp connections
present in all tissues .
Habitat & Distribution: Solitaryon lawn . Rather rare, only
found in southwestern China .
Specimen examined: China: Yunnan Province, Lijiang
City, Yulong SnowMountain, alt . 3 100 m, 4 VIII 2005 , J . F .
Liang 186 (HKAS 48802) .
Remarks: Lepiota jacobi is characterized by its umbonate
pileus coveredwithgrey todark brownacute spines, small basidios-
pores andthe absenceof cystidium (Knudsen, 1978 , 1980; Enderle
and Kriegelsteiner, 1989; Vellinga, 2001) . Thenameof the species
was originallydescribedas Lepiota langei by Knudsen (1980) , but
heoverlooked Lepiota langei validly published by Locquin (1945) .
Thus, the new name, Lepiota jacobi Vellinga& Knudsen in honour
of JacobE . Lange, was proposed by Vellinga (1992) .
