Taxonomic position and nitrogen-containing secondary metabolites of the fungusPenicillium vitale pidoplichko et bilai apud bilai

The type strainPenicillium vitale Pidoplichko et Bilai apud Bilai 1961 VKM F-3624 was found to considerably differ from a sibling speciesP. janthinellium (syn.P. simplicissimum) in some physiological and morphological features (growth rates at different temperatures, the size of philiades, and the shape of conidia), as well as in the pattern of the nitrogen-containing secondary metabolites produced (roquefortine, 3,12-dihydroroquefortine, meleagrin, aurantioclavine, indole-3-acetic acid, andN-acetyltryptamine). The data obtained suggest thatP. vitale represents an independent species.

Halosarpheia unicellularis sp. nov. (Halosphaeriales, Ascomycota) based on morphological and molecular evidence

Halosarpheia unicellularis sp. nov. is described from decayed attached wood ofAvicennia marina collected from two mangrove sites in the Red Sea, Egypt. The ascomycete is compared with other marine taxa having ascospores with polar unfurling appendages. It is also compared with other marine genera with oval, round or ellipsoid hyaline, unicellular ascospores, but for which appendages have not been reported. Molecular data confirms the assignment of the fungus toHalosarpheia which forms a clade with the type speciesHalosarpheia fibrosa.
