New insights on the Xylaria species (Ascomycota, Xylariales) with bright-coloured exudates: Xylaria aurantiorubroguttata sp. nov. and revision of X. haemorrhoidalis and X. anisopleura type collections.

A new species of Xylaria is described based on morphological characters of both sexual and asexual morphs, and molecular data based on nuclear rDNA internal transcribed spacer, α-actin, β-tubulin and RNA polymerase subunit II sequences. Xylaria aurantiorubroguttata is characterized by the presence of both upright, cylindrical, long-stipitate and globose to subglobose, short-stipitate stromata, immature stromatal stages producing at first orange and then red drops, and ascospores with a slightly oblique, straight half spore-length germ slit. We provide also new morphological descriptions for X.

Taxonomic Re-Examination of Nine Types (Ascomycota, Xylariales) Stored in the Saccardo Mycological Collection.

In a recent monograph on the genus , type specimens worldwide were revised and re-classified using a morphological approach. Among them, some came from Pier Andrea Saccardo's fungarium stored in the Herbarium of the Padova Botanical Garden. In this work, we taxonomically re-examine via a morphological and molecular approach nine different Saccardo types.
