*Corticifraga peltigerae (Nyl.) D. Hawksw. & R. Sant.<br />
<strong>Luxembourg</strong>, Lorr.: entre Dudelange et Kayl, Haard (M8.54), sur de la terre, sur Peltigera<br />
rufescens, 7.2002, P. Diederich 15490 (h), J. Miadlikowska & D. Ertz; W <strong>of</strong> Kayl, Monument<br />
des mineurs (M8.53), on P. rufescens, 10.2002, P. & B. van den Boom 29875 (h).<br />
Within the study area this species was known only from two old records<br />
(< 1880) from B Ard. (DIEDERICH & SÉRUSIAUX, 2000: 95). It is new for <strong>Luxembourg</strong>.<br />
*Dinemasporium strigosum (Fr.) Sacc.<br />
<strong>Luxembourg</strong>, Lorr.: entre Dudelange et Kayl, Haard (M8.54), sur de la terre, sur<br />
Peltigera rufescens, 7.2002, P. Diederich 15493 (h), J. Miadlikowska & D. Ertz 2529<br />
(BR); Lorentzweiler, Kiischtebierg (L8.45), dans une l<strong>and</strong>e siliceuse, sur Peltigera<br />
hymenina, 11.1983, P. Diederich 3961 (h).<br />
This is a common coelomycete, mostly, but not exclusively, growing on<br />
graminaceous substrates (SUTTON, 1980). The repeated discovery <strong>of</strong> the fungus<br />
on thalli <strong>of</strong> Peltigera (see also MIADLIKOWSKA & ALSTRUP, 1995) suggests that<br />
these populations might represent a distinct, yet undescribed, lichenicolous<br />
species. More <strong>and</strong> richer collections are needed to ascertain this hypothesis. Nonlichenicolous<br />
specimens are known from <strong>Belgium</strong>, e.g.: <strong>Belgium</strong>, Ard.: Malmedy<br />
(G8.43), on Deschampsia flexuosa, s. d., M. A. Libert, Reliquiae Libertianae n°23<br />
(BR). We did not check the Belgian mycological literature to see if the species was<br />
already published from this country. In any case, the species must be added to the<br />
checklist <strong>of</strong> lichens <strong>and</strong> lichenicolous fungi (DIEDERICH & SÉRUSIAUX, 2000).<br />
Endocarpon adscendens (Anzi) Müll.Arg.<br />
<strong>Belgium</strong>, Mosan: 2 km N <strong>of</strong> Villers-sur-Lesse, in front <strong>of</strong> entrance to Château Royal<br />
(J6.13), S exposed mossy slope in ditch, 5.2001, P. van den Boom 26495 (h).<br />
Both previously known specimens <strong>of</strong> this species from the study area,<br />
preserved in LG, were re-checked <strong>and</strong> found to represent E. pusillum Hedw.<br />
However, a recently collected Belgian specimen proved to be the genuine E.<br />
adscendens (identification confirmed by Dr O. Breuss). The presence <strong>of</strong> this<br />
species in the study area is thus established. The species was growing close to<br />
Protopannaria pezizoides.<br />
*Epicladonia stenospora (Harm.) D. Hawksw.<br />
Bull. Br. Mus. Nat. Hist. (Bot.) 9: 20 (1981); Aposphaeria stenospora Harm., Lich. Fr.<br />
3: 308 (1907). Type: not indicated in the original account (type lost ? ANGUC–, fide<br />
HAWKSWORTH 1981).<br />
<strong>Luxembourg</strong>, Lorr.: NW <strong>of</strong> Steinfort, carrières (L8.51), alt. 320 m, sur de la terre,<br />
sur Cladonia furcata subsp. furcata, 1.2000, J. M. Cepeda 46a (LG – neotype, here<br />
designated; LUX, UPS, hb Diederich – isoneotypes).
