A phylogenetically based comparative analysis of onshore-offshore distribution patterns of mushroom coral species (Scleractinia: Fungiidae) was made to reconstruct an evolutionary scenario for differentiation in fungiid shelf habitats. This phyloecological study integrates data on fungiid distribution patterns along environmental gradients on the Spermonde Shelf, SW Sulawesi, with a recently published phylogeny reconstruction of the Fungiidae. A mushroom coral fauna of 34 species was used to compare their distributions by use of 50-m2 belt quadrats in transects (1) from the mainland to the shelf edge, (2) around reefs with regard to predominant wind directions, and (3) over bathymetrical reef zones. Species association ordinations were made for each of the four shelf zones using both abundance and incidence data to examine whether closely related species cooccurred. Some closely related species or even sister species appeared to show very similar distribution patterns and to coexist in high abundances. These results indicate that there may not be community saturation and competitive exclusion among mushroom corals species, most of which are free-living. In reconstructions of fungiid habitat evolution, offshore reef slopes appear to be original (ancestral), whereas onshore habitats, shallow reef flats, and deep sandy reef bases seem to be derived. The latter is in contrast with an earlier hypothesis, in which deep sandy substrates were considered ancestral mushroom coral habitats.

The evolution of symbiotic relationships involving reef corals has had much impact on tropical marine biodiversity. Because of their endosymbiotic algae (zooxanthellae) corals can grow fast in tropical shallow seas where they form reefs that supply food, substrate and shelter for other organisms. Many coral symbionts are host-specific, depending on particular coral species for their existence. Some of these animals have become popular objects for underwater photographers and aquarists, whereas others are hardly noticed or considered pests. Loss of a single coral host species also leads to the disappearance of some of its associated fauna. In the present study we show which mushroom corals (Scleractinia: Fungiidae) are known to act as hosts for other organisms, such as acoel flatworms, copepods, barnacles, gall crabs, pontoniine shrimps, mytilid bivalves, epitoniid snails, coralliophilid snails, fish and certain types of zooxanthellae. Several of these associated organisms appear to be host-specific whereas other species are generalists and not even necessarily restricted to fungiid hosts.Heliofungia actiniformisis one of the most hospitable coral species known with a recorded associated fauna consisting of at least 23 species. The availability of a phylogeny reconstruction of the Fungiidae enables comparisons of closely related species of mushroom corals regarding their associated fauna. Application of a phylogenetic ecological analysis indicates that the presence or absence of associated organisms is evolutionarily derived or habitat-induced. Some associations appear to be restricted to certain evolutionary lineages within the Fungiidae, whereas the absence of associated species may be determined by ecomorphological traits of the host corals, such as coral dimensions (coral diameter and thickness) and polyp shape (tentacle size).

<strong>Biodiversity and Distribution of Mushroom Coral (Fungiidae) in The Amurang Bay, South Minahasa.</strong> Mushroom coral is the one of sclerectinians that has essential role to form coral reefs. This kind of species act as a microhabitat for other marine organisms such as shrimp. cryptobenthic fish, barnacle and crab. Most of these unique species have an ability to move from one habitat to another during benthic phase. The aim of this research was to determine the community structure and distribution of mushroom corals. This research was conducted in February 2017 at 4 research stations using belt transect method with  50x2m<sup>2</sup> length of transects. The results showed that 431 individuals consisting of 19 species and 11 genus were recorded. Generally, the range of values of diversity index (H) was between 0,85-1,06  (low to medium level). The evennes index (J) values was ranged from 0,81 to 0,89 (high level) while the richness index (D) was 2,47-3,58 (low level). Lythophyllon repanda, Lythophyllon concinna and Fungia fungites were the most dominant mushroom coral spesies in the Amurang Bay waters.

Mushroom coral is one of the component of hard coral family in ordo Scleratinia where this life was free living on substrate. Structure community of mushroom coral study in the waters of the Banggai Archipelago in Central Sulawesi province has not been done much. Observation on community structure of mushroom coral at Banggai Archipelago waters was conducted on July 2011. The purpose of this study  to determine the species composition, diversity, evenness, density and dominance species of musrhoom coral.The method used in this research is belt transects that made ​​ parallelly extended to the shoreline with the size of 100 x 3 m2. Mushroom coral species observation done visually by counting the number of species.  It was found 27 species belong to 10 genus of mushroom corals. The highest diversity index (H) was 1,19 at station 9 and the minimum was 0,95 at station 4.  The highest avenness index (j) was 0,69 at station 3 and the minimum was 0,44 at station 8.  The highest dominance index (D) was 0,14 at station 7 and minimum was 0,08 at station 6.  Identification results shows that there are 5 species of mushroom coral found in the 9 station, which is Fungia concinna, F. repanda, F. fungites, F. costulata and Herpolita limax. Keywords : community structure, mushroom coral, banggai archipelago, Central Sulawesi   ABSTRAK Karang jamur merupakan salah satu family karang batu yang masuk dalam ordo Scleractinia dimana hidupnya bebas pada substrat. Penelitian mengenai struktur komunitas karang jamur di perairan kepulauan Banggai propinsi Sulawesi Tengah belum banyak dilakukan. Pengamatan struktur komunitas karang jamur di perairan Kepulauan Banggai telah dilakukan pada bulan Juli 2011. Tujuan penelitian ini yaitu untuk melihat komposisi jenis, keanekaragaman jenis, kemerataan jenis, kepadatan dan dominansi jenis karang jamur.  Metode yang digunakan dalam penelitian ini yaitu transek sabuk yang dibuat memanjang garis pantai dengan luas transek 100 x 3m². Pengamatan jenis karang jamur dilakukan secara visual dengan menghitung jumlah tiap jenis.  Hasil analisis menunjukkan jumlah jenis karang jamur yang ditemukan sebanyak 27 jenis yang mewakili 10 marga.  Indeks keanekaragaman jenis (H) tertinggi dijumpai di stasiun 9 sebesar 1,19 dan terendah di stasiun 4 sebesar 0,95.  Indeks kemerataan jenis (j) tertinggi ditemukan di stasiun 3 sebesar 0,69 dan terendah di stasiun 8 sebesar 0,44.  Indeks dominansi jenis (D) tertinggi dijumpai di stasiun 7 sebesar 0,14 dan terendah di stasiun 6 sebesar 0,08.  Hasil identifikasi jenis menunjukkan ada 5 jenis karang jamur yang ditemukan di 9 stasiun yaitu Fungia concinna, F. repanda, F. fungites, F. costulata dan Herpolita limax.
