When: 2011-04-06

Collection location: Sintra, Portugal [Click for map]

Who: zaca

No specimen available

Notes:
This observation revelled to me one more surprise. At first I didn’t had any idea about the classification of these cup fungi. After searching, I found they were similar to Bulgaria inquinans. Then the observation of the spores showed a spherical shape (~11.7 µm in diametre) . Another search and I came to svims with a key to Sarcosomataceae in the Pacific Northwest, which is a bit farway from my homeland. Anaway, there I could find a promising species for the classification: Pseudoplectania nigrella. According to that reference, a distinctive feature of this species is “margin slightly incurved and often wavy, stiff with brown hairs best seen under 10x hand lens”.

Great find! Pseudoplectania nigrella contains a powerful natural antibiotic (Plectasin):
