Facesoffungi number: FoF 04203
Saprobic on soil or pathogenic on endosperm and embryo of Sitka spruce seed. Sexual morph: Apothecia up to 5 cm diam., gregarious, sessile to short stipitate, exterior surface dull yellow to yellowish-orange, with maturity become bluish-green to olive, especially near the margin. Receptacle cupulate, sometimes discoid at maturity. Margins lobed, concolorous to receptacle. Disc yelloworange to orange, glabrous. Paraphyses filiform, granulated. Asci 8-spored, operculate, inamyloid. Ascospores 5.5–7.5 µm, globose, smooth, hyaline. Asexual morph: Colonies on PDA coarse, white to pale brown. Aerial mycelium densely verrucose, white to pale brown. Submerged mycelium smooth, white, orange or brown. Conidiophores straight, erect, cylindrical, septate, highly branched, forming hyaline, dendroid structures, with a main axis, ultimate branches bearing conidiogenous cells. Conidiogenous cells polyblastic, borne singly, in pairs or verticillately and proliferating sympodially. Conidia form in successive apices of conidiogenous cells from sympodial succession, dry, acropetal, holoblastic, arising in clusters, aseptate, hyaline, pyriform, smooth-walled, guttulate, truncate at the attached end (Description modified from Salt 1974; Beug et al. 2014).
Notes: The sexual morph of Caloscypha fulgens is saprobic on soil and characterized by yellow apothecia which become bluish-green to olive at maturity, cylindrical operculate asci and globose hyaline ascospores (Beug et al. 2014). The asexual morph of Caloscypha fulgens is pathogenic on endosperm and embryo of Sitka spruce seed and characterized by its sympodially proliferating conidiogenous cells from which unicellular holoblastic conidia are formed (Salt 1974).
