Taxonomy of Philippine Lichens
09/2014 ~~ Interesting lichen in the Philippines whose record online was only in 1909 GBIF or Field Museum wise [in the Phil.] has "sprouted out" outside of the Baguio, Cordillera, Mindoro areas. This is found outside of the island of LUZON. This is Cladia aggregata (Sipman, H.) It is famous for its perforations. Please see image below.

Congratulations! and We'll support your interest in lichens especially your plan for an extensive lichenological work in your country the first ever. I would like to see you as the only African expert on lichens in Africa. (expecting...)

9/23/2009~~Pyxine cocoes , a foliose lichen, as a bioindicator/ biomonitor for aerial pollution was first reported in Iloilo City, Philippines in 2003: An Update
Isidro T. Savillo*
*Lichenologist, Iloilo, Philippines
Pyxine cocoes was first reported in 2003 by Savillo, I. in his publication titled “The Common Abundance of Pyxine cocoes (Swartz)Nyl. in district parks of Iloilo City, Philippines” where he concluded that “Pyxine cocoes being abundant, may serve as a good bioindicator for atmospheric pollution and further cellular analysis would reveal its actual physiological characteristics.” This finding was presented in a Regional Convention (Region VI) of the Philippine Society for Microbiology and this study was granted a Wildlife Gratuitous Permit No. 101 of the DENR. Pyxine cocoes has been reported as a pollution tolerant lichen by the following: Thrower in 1988 (Hongkong), Nayaka et al in 2003 (India) and Saipunkaew et al in 2004 (Thailand). In 2009, Gruezo and his team from U.P Los Banos, U.P. Diliman and Philippine Nuclear Research Institute had come up with a publication titled “Lichen Pyxine cocoes (Sw.) Nyl. (Physciaceae) as a potential biomonitor for atmospheric pollution in Southern Luzon, Philippines.” Their study area spanned four Metro Manila sites and two sites near and around coal fired power plants where they concluded that the lichen Pyxine cocoes (Sw.) Nyl. (Physciaceae) as being abundant and ubiquitous in all their six study sites hence they considered it as potential biomonitor for atmospheric pollution after analyzing the samples for several air pollution related elements using xray fluorescence spectrometry. This finding has supported the first pioneering report of Savillo, I. in 2003 in the Philippines regarding the common abundance of this lichen and its usefulness in determining atmospheric pollution. In Savillo’s presentation titled “Lichens in Mangroves” in the 2009 Society of Wetland Scientists Convention in Madison, Wisconsin , he emphasized that Pyxine cocoes favorably grow in trees adjacent residential areas or areas frequented by humans. In fact these are far from sources of industrial pollution and far from the city. There may be an intriguing factor(s) responsible for their growth where there is a need to meticulously analyze this factor(s) as pollutant or not. Saipunkaew (2004) in her lichen study used population density as a surrogate measure for pollution levels due to inadequate pollution data.
This Web Page is dedicated to the Taxonomic Identification of Philippine Lichens. New species and varieties as well as those subjected to nomenclature change/modification will be highlighted with their photographs displayed. Welcome to the Lichens of the Philippines Information Center!
New*~Pyxine cocoes* has been cited in scientific articles as common and abundant as well as pollution tolerant/ bioindicator for aerial pollution in tropical cities:
2003- in Bangalore City, India
2003- In Iloilo City, Philippines- recommended as a bioindicator for aerial pollution
back- up copy- originally published
2004- in Cities of Northern Thailand
2009- In Southern Luzon, Philippines
Pyxine cocoes 2014 update is above below heading.
Pyxine cocoes could be a good bioindicator/biomonitor for atmospheric pollution. First, it is widespead, could be seen in areas of anthropogenic disturbances, second, it tolerates high pollution levels- imagine P. cocoes a few of them growing in trunks (with black soot) of trees in a mid road island cloaked by polluted air from heavy traffic at least 24 hrs a day.,third, it could be used in active biomonitoring (as what they did in India) and 4rth, it could be used to assay for most important atmospheric particulates (e.g. elements). In this sense, using P. cocoes one could make comparative values of aerial pollutants from different areas where it grow. (Pabroa et al., UPLB study). One lichen, One sweep.

*By going places, unexpectedly , one encounters interesting lichens thus these two forthcoming articles: A Foliicolous Lichen Encountered in Guimaras Island and the other article, Ramalina sp. at an aging Ceiba pentranda. The latter was on the middle of a farmland of a former student. The Foliicolous lichen was seen on leaves of a Croton and that of a young shrubby mango comprising the garden infront of a nipa house. How surprising that they add to the decorative looks of the plants!! As if it was just a part of a garden...but was never cultivated! A product of "unconscious" gardening.

11/2007~UPDATE: (From the Internet- Posted March 9, 2007)-A certain Phil
( I assumed a lichenologist? on a tour) went for two weeks to Iloilo City , Philippines to study lichens. As to his findings it was quoted that Iloilo City is one of the few places in the world where certain corticolous lichens grow and that the church yards and buildings were some of the best places to find these lichens. It was also stated that in a headstone named Liwayway (where is this??) nearly 50% was covered with Pyxine cocoes (on the spot i.d.?- Could have been an expert lichenologist to do this- Are you from HUH?) Very supportive for the Biologybrowser published paper of Prof. Isidro T. Savillo- The Common Abundance of Pyxine cocoes in district parks of Iloilo City, Philippines
Cheers for 2009 Lichen thesis student from Mindanao, the photographs of samples are very interesting especially the fruticose ; Cheers for the 2006 - 2007 Lichen Enthusiasts: These include the Ateneo De Manila University Lichen Group of Students, Thesis student from the Pamantasan ng Lungsod ng Maynila, U. P. Diliman Lichen Group of Students and a PhD student from the University of Tokyo. Their interests vary from taxonomy of lichens in campus, inventory of lichens in the La Mesa Dam, lichens as pollution indicators and bioactive substances from lichens. Thanks for your interactions with me and I am willing to be of help but in one condition- it has to be publishable (2014). 5/2014``A graduate student from Indonesia also requested for reference assistance specifically P.cocoes for her thesis. Thanks.

-- Below is a photo of a Cryptothecia [cf] taken during an educational trip. This is as big as a human face. Unlike some crustoses where their being widespread is a result of the overlapping growths of crustose and foliose lichens, this one is in itself "uncontaminated" individual lichen. It is "axenic".
