Abstract

ITURRIAGA, Teresa; MARDONES, Melissa  and  URBINA, Héctor. A new species of Pseudoplectania (Sarcosomataceae, Pezizales) from Venezuela. Kurtziana [online]. 2012, vol.37, n.1, pp. 73-78. ISSN 1852-5962.

A new species of the genus Pseudoplectania (Sarcosomataceae, Pezizales) was collected on wood in a tropical forest in southern Venezuela, at Gran Sabana, Canaima National Park, Bolívar State; species of the genus Pseudoplectania are characterized by having a deep cup shaped sessile or stipitated apothecia, covered by coiled or twisted hairs, J- asci containing 8 globose, smooth, hyaline ascospores; the new species can be distinguished from the rest of the species in the genus in having small short-stipitate apothecia, cylindrical hyaline paraphyses and ascospores with small scattered warts visible only in material stained with aqueous Congo Red; ornamented ascospores have not been previously described in the genus.

Keywords : Discomycetes; Ascospore ornamentation; Congo Red; Pseudoplectania; Neotropics; Fungi.
