Observation 48983: Trentepohlia Mart.
When: 2010-07-17
Collection location: Sintra, Portugal [Click for map]
Who: zaca
No herbarium specimen

Notes: In the webpage of Alan Riverside in the section dedicated to “Photobionts” I found the solution to a mystery that puzzled me for some time.
When in the observation MO46790 I proposed the classification of Fungi sp. , I was convinced that would be the case. This time, near the site of that observation, I returned to find a tree (pine) dressed in ocher (as photographs illustrate). I was again intrigued and decided to investigate. After some time got from Alan Riverside’s page a link with the information about a genus of green alga (although the color observed is yelow-orangish due to the presence of beta-carotene), Trentepohlia, with various species of shade more yellowish or more reddish, and is likely that my specimens belong to be one these species.
According to information from the page above, this type of algae occurs as a photobiont in lichens of the genus Opegrapha.
It seems to me that Trentepohlia is the genus of the specimen presented in MO44078, by Darv.
