Geoporcı cooperi Harkness f. cooperi Burdsall, a macrofungus belonging to the Asconıycetes

collccted during a ficld trip around İzmir and Manisa in 1996 is rcportcd as a ııcw rccord for wcsl Asia, Turkcy.

Geopora cooperi an ascomycete belonging to the family Otideaceae order Pezizales, is hypogeous and edible macrofungus (Anon., 1987). The only previous records are from North America and Europe (Burdsall, 1968; Moreno et al., 1986; Montecchi & Dal Forno, 1995). This article presents the world distribution of one of the species of Geopora and expands its known arca. It is a new record for the Turkish macrofungi.

Fruit bodies ascocarps 2-5 cm broad, globose to subglobose, hypogeous or rarely epigeous, outer surface irregularly furrowed, margin differeııtiated, opening to tlıe

exterior orientecl raııclomly with respect to the soil surface, inconspicuous, the ascocarp covered by brown hairs giving thc surface a fuzzy appearance, honey colored to clark brown; interior white to whitish, deeply convolutecl, convolutions oftcn contacting eaclı

other but remaining separate, outer surface following the interior of the convolution, giving each invagination; when viewecl in section a thin !ine of brown pigmentation clown the miclclle (Fig. la). Outer ectal excipulum a textura angularis, of cells up to 40 µ thick

in outcrınost cells, yellow-brown, inner cclls of this tissue hyaline and thin-walled,

intergrading into the inner ectal excipulum (Fig. I c ). Excipular ha irs abundant, superficial, up to l mm or more in length (most broken when collected), 8-14 µ broad, mostly thick-walled (l-4 µ thick) yellow-brown, others hyalinc or thin-wallcd, flexuous, simple or branched, septate, sometimcs encrusted with large granules over the entire surface, arising from surface cells of outer ectal excipulum, apex obtuse, basa! celi often somewhat swollen except at the margin. Marginal ha irs Iess flexuous (Fig. 1 d). Inner ectal excipulum a texture intricata of thin-walled hyaline cells, 6-10 µ broad, intergrading on the outside into the outer ectal excipulum and on the inside into the subhymeniuın

which is usually not well-defined (Fig. le). Ascospores broaclly oval, elliptical, sometimes collapsing on one side and appearing reniforın, hyaline, smooth, thin-walled, 20-27 x 13-17 µ. Asci cylindrical, tapering to the base to a crozier, 80-27 x 15-22 µ, operculate, usually 8 sporecl (Fig. 1 b ). Paraphyses hyaline, septate, thin-walled, 2-4 µ broad, sometimes swelling to 5-8 µ at apex, extending to the vicinity of the ascus apices. Habitat on soil under pines. Distribution between İzmir and Manisa, on soil undcr pine forests, l January 1996, S. 565.
