Pseudopithyella minuscula  

Anamorph: not known.
Teleomorph: ascomata apothecia, to ca 2mm diam. (dried material), single or in clusters, reddish orange to scarlet, tapering below to a usually short broad ± hyaline stalk to ca 800 µm in length. Internal tissues composed of intricately coiled and branched hyaline fairly thick-walled hyphae 2.5-4 µm diam., the surface sometimes brown (perhaps due to overgrowing saprobic fungi). Disc ± flat, the marginal tissues appearing as a narrow slightly paler exciple when fresh, composed of a layer 40-50 µm thick of aggulinated parallel hyphal tissue with individual hyphae 3-4 µm diam. and containing some globules of carotenoid pigment (not as well-developed as in the paraphyses). Interascal tissue of unbranched thin-walled paraphyses ca 1.5 µm diam., hardly swollen (to ca 2 µm diam.) at the narrowly clavate apices, containing copious globules of orange carotenoid pigment. Asci 200-280 x 11-14 µm, narrowly cylindrical with a long gradually tapering stalk, fairly thick-walled but not fissitunicate, with a conspicuous thickening around the ± truncate apex, usually 8-spored. Ascospores arranged biseriately, 14-16 x 8-9 µm [rehydrated material, apparently mature ascospores within asci], ellipsoidal, fairly thick-walled, aseptate, hyaline, smooth, often containing two large guttules, immature spores with a broad perispore which is not visible at maturity.
