FUNGI REALM

Impossible to accurately describe the fungi. A ubiquitous being in living creatures on the planet, with about 140,000 spp. described, but estimates of 2.2 to 3.8M (Wikipedia). In archaic publications and even in modern magazines, they are associated with plants, although they are much closer to animals. But in the modern web of life, fungi are a unique lineage among the 78 already listed of prokaryotes.

Yes, modern fungi, animals and plants are just three of the 78 lineages of eukaryotic life forms. The other 75 were formerly part of the Protista, with some formerly thought to be fungi, now thought to be independent.
PHYLOGENETIC TREE OF FUNGI; CLICK FOR FULL SIZE

In this post, we will not talk about fungi as a whole. For those who want to know super details of the evolution of this group, we recommend Ortiz & Gabaldón (PMC/2019). Here we discreetly list three types of fungi interesting from the perspective of Almanaque Z: the truffles (Tuber), the aquatic basidiomycota and the bioluminescent fungi.

PHYLOGENETIC POSITION OF THE FUNGI THAT WILL BE DISCUSSED HERE

TUBER, TUBERACEAE, PEZIZIALES

Tuber P.Micheli ex F.H.Wigg., true 'truffles', is a genus in the Tuberaceae family of fungi, with estimated molecular dating to the end of the Jurassic period (156 Mya). It includes several species of truffles that are highly valued as delicacies. According to the Dictionary of the Fungi (2008), this widespread genus contains 86 spp. In 2015 a new species T. petrophilum Milenković, P. Jovan., Grebenc, Ivančević & Marković, in Milenković, Grebenc, Marković & Ivančević was discovered in the Dinaric Alps (Southeastern Europe, Serbia). In 2016, two new species were discovered in introduced trees of pecans cultivated in Brazil but putatively native from North America, T. floridanum A. Grupe, Sulzbacher & M.E. Smith and T. brennemanii A. Grupe, Healy & M.E. Smith. (Wikipedia).

AGARICALES

Agaricales includes about 13,000 described mushrooms, and it includes all the mushrooms that we want to highlight here: the bioluminescent mushrooms and the aquatic mushrooms.

BIOLUMINESCENT

Worldwide, among the luminescent species, 125 species of mushroom-forming fungi have been recorded to date. These fungi represent five distinct lineages

Armillaria Armillaria species at Physalacriaceae (12 spp.), absents in South America.

Mycenoid ‣ 4-8 genera with bioluminescents, Mycena, Filoboletus (manipularis group), Panellus (Panellus/Dictyopanus species), Roridomyces, and Resinomycena (a single bioluminescent, exclusive from SE Brazil), all anchored in the family Mycenaceae. 17 luminescent species in Brazil (Soares, C.B. et al, Phytotaxa, 2024), three in Amazonia Complex.

Omphalotus ‣ (4/)12 bioluminescent spp. (Wikipedia), Neonothopanus (2) and Omphalotus (10, California to Texas and NW & N Mexico,  E U.S.A., SW South Africa, S China to Japan in E Asia, S Australia to Tasmania) plus Nothopanus eugrammus (Japan to Malaysia) and Pleurotus decipiens, only the former in N & NE Brazil (Neonothopanus gardneri), mainly in palms.

Lucentipes ‣ two species: Gerronema viridilucens, described in 2005 based on material collected from the bark of living Eugenia fluminensis O.Berg. trees in S São Paulo State in SE Brazil; and Mycena lucentipes Desjardin, Capelari & Stevani, knwoon from SE Brazil and Puerto Rico (Desjardin et al., Mycologia, 2005); both form an independent lineage of bioluminescent fungi with uncertain phylogenetic position at the family level.

Eoscyphella ‣ a single species, exclusive from Brazil, Eoscyphella luciurceolata Silva-Filho, Stevani & Desjardin, known from a bark of Solanum swartzianum in the Atlantic Rainforest, southern Brazil. Known only from the type locality (Silva-Filho et al., Journal of Fungi, 2023).

By IPBio (VER) there are 105 spp. in the world, 17 described 12 not yet described in Brazil, mostly in the Atlantic Forest, making the forest a global hotspot for this unique type of fungus.

SOME LIGHT MUSHROOMS FROM ATALNTIC FOREST OF BRAZIL

UNDERWATER

Basidiomycota that fruit in water include only Psathyrella aquatica J.L.Frank, Coffan, & Southworth, 2010 (Wikipedia), in family Psathyrellaceae, found only in the Rogue River in Oregon, USA. It was found by Southern Oregon University professor Robert Coffan in the Rogue River in the U.S. state of Oregon. Coffan and his colleagues, Darlene Southworth and Jonathan Frank, found the mushroom in 2005. The biology department at Southern Oregon University confirmed that the mushroom was a unique discovery. Once their research was published, it was named one of the most significant species discovered in 2010. They have so far been discovered in a 1 kilometer stretch of the river, and have an observed fruiting season of mid-June to late September. Many scientists were skeptical about describing this mushroom as a new species because of the hundreds of similar looking species in the Psathyrella family.

Psathyrella aquatica J.L.Frank, Coffan, & Southworth in situ, Oregon, U.S.A.

ECTOMYCORRHIZA

An ectomycorrhiza (ECM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota, among 78-82 fungal lineages that comprise 251-256 genera (Tedersoo & Smith, Fungal Biology Reviews, 2013). Ectomycorrhizas form on the roots of around 2% of plant species,[1] usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families (Wikipedia). Pseudotulostoma volvatum OK Mill. & TW Henkel has the first occurrence of an ectomycorrhizal Ascomycota fungus in a native host plant in Brazil, in white-sand forest composed of the canopy tree Aldina heterophylla Spruce ex Benth. (Fabaceae) in NE Amazonas state (Komura et al., Plant Systematics and Evolution, 2021).

TERRESTRIAL PLANTS IN SOUTH AMERICA✅

The Embryophyta, or land plants, are the most familiar group of green plants that comprise vegetation on Earth. Embryophytes have a common ancestor with green algae, having emerged within the Phragmoplastophyta clade of green algae as sister of the Zygnematophyceae. Living embryophytes therefore include hornworts, liverworts, mosses, lycophytes, ferns, gymnosperms and flowering plants. The tree below is one of the most consensual about the evolution of the group (Wikipedia). Bryophyta s.l. are a proposed taxonomic division containing three groups of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses.

The most complete data from bryophytes in Neotropics is Hallingbäck and Nick Hodgetts (Mosses, Liverworts, and Hornworts, 2000), assignated here as [1]; some data also in Delgadillo (Bol. Soc. Bot. Mexico, 2000).

In summary, Colombia has advantage of 5 spp. against Brazil in Marchantiophyta (no advantage in genera), 65 spp. in Bryophyta (no advantagem in genera), and none advantages in Anthocerophyta. Mexico no has advantages against Brazil in Marchantiophyta and Anthocerophyta, and an advantage of 4 families, 57 genera and 114 spp. in Bryophyta.

PHYLOGENETIC TREE OF VIRIDIPLANTAE

MARCHANTIOPHYTA

Liverworts has (87:386/)7,273 spp. worldwide, by Lars Söderström et al.  (PhytoKeys, 2016). 

Colombia has (37:134/)703 spp. (37 endemics; CTLC, BOOK, 2016); Brazil has (39:132/)698 spp. (Reflora, 2023; 143 endemics). Brazil has 3 families absents in Colombia (Chonecoleaceae, Oxymitraceae, Sphaerocarpaceae); Colombia has one family absent in Brazil: Pseudolepicoleaceae (3/3 in country). Mexico includes (122:)592 spp. [1] and varieties in this class (Delgadillo-Moya, Botanical Sciences, 2022).

By [1], endemic genera occur in northern Andes (7), Amazonia (5), Guianan Highlands (4), SE Brazil (2, Pluvianthus, Vittalianthus), and Chocó (1); Geocalycaceae is placed under Lophocoleaceae in CPLC, and Solenostomataceae under Jungermanniaceae. 

BRYOPHYTA

Mosses has c. 12,000 spp. worldwide (Wikipedia). Colombia has (65:261/)932 spp. (52 endemics; CTLC, BOOK, 2016). Brazil has (71:268/)867 spp. (209 endemics; largest diveristy of genera, 8 endemics, Costa, D.P. et al., The New York Botanical Garden Press, 2023). Mexico has (75:325/)984 spp. (Delgadillo-Moya, Rev. Mex. Biodiv. vol.85, 2014).

Dendrocerotaceae has a genus in Colombia absent in Brazil (Phaeomegaceros R.J.Duff); Brazil has one genus in Anthocerotaceae absent in Colombia (Folioceros DC); and both countries has a exclusive family againt the other: Phymatocerotaceae (Phymatoceros Stotler, W.T. Doyle & Crand.-Stotl.) in Brazil, and Leiosporoceroaceae (Leiospoceros Hässel) in Colombia. Mexico has (3:3/)9 spp. in this class, among Anthoceros, Nothoceros and Phaeoceros, plus at least 7 undescribeds (Delgadillo-Moya, Botanical Sciences, 2022), 3 endemics.

NEW WORLD ORCHIDACEAE✅

PLESOM

On October 9, 2022 the VPA (SEE) listed 14,632 orchids (species, notospecies and natural hybrids) in New World, 11,740 of which in South America. Of the more than 350 genera of Orchidaceae in the hemisphere, a group of six genera stands out: the PLESOM group, formed by Pleurothallis, Lepanthes, Epidendrum, Stelis, Oncidium and Masdevallia. These genera together have 5,820 spp., about 40% of all Neotropical diversity; in South America they are 4,773 spp., which is also around 40% of the local amount.

Vanilla, Habenaria, Corymborkis, Bulbophyllum, Polystachia, Calanthe, Tropidia, Liparis, Malaxis and Eulophia are the only South American genera not restricted to New World.

By country, Brazil has the 3ª greatest diversity of orchids in the world, behind its (quasi-)neighbors Colombia and Ecuador. By the way, the national family diversity in these countries is the largest for a single family in a single country ever described. Ecuador at 2,228 of its 4,289 spp. belonging to PLESOM (c. 52% of its national diversity); Colombia has 1,818 of its 4186 in PLESOM (c. 43% of national diversity). Brazil has in PLESOM only 269 spp. of its 2,734 spp., less than 10%.


Excluding the PLESOM group, we have the following national diversities: Ecuador 2,061; Colombia 2,368; Brazil 2,465. The numbers show that the very high diversity of Orchidaceae in the two Andean countries is due to an explosion of diversity in the PLESOM group; outside of it, Brazil has more diversity of Orchidaceae.

OVER GENERIC DIVERSITY

All South American Orchidaceae tribes occur in Brazil except Colllabieae (20/443), which has its only South American species in Colombia (Calanthe calanthoides (A. Rich. & Galeotti) Hamer & Garay). Brazil has 203 genera, Colombia has 230 and Ecuador 217.

SOUTH AMERICAN GENERA BY GROUP; FOR BRAZIL, /BR DENOTES ABSENT GENERA; [BR] DENOTES ENDEMIC GENERA.
In the subfamilies Vanilloideae and Cipripedioideae, Brazil and Colombia have all 6 South American genera; Ecuador and Peru 5 of them (except Duckeella). In species at Brazil against Colombia, Brazil wins in Vanilloideae for 22 spp., and Colombia wins Brazil in Cipripedioideae for only one species.

In the subfamily Orchidoideae (Microchilus inc. AspidogyneKreodanthus, Platythelys, Stephanothelys; Solenocentrum absent in Colombia), South America has 52 genera, Brazil and Peru have 31 each, Colombia has 30, and Ecuador has 32; national endemic genera in this subfamily occur only in Brazil (4, Espinhassoa, Thelyschista, Cotylolabium and Nothostele) and Venezuela (2, Aracamunia and Stalkya). Brazil has more Orchidioideae species than Mexico and Colombia.

Degranvillea dermaptera Datermann from French Guiana and Suriname is the only South American mycoheterotrophic orchid outside Epidendroideae.

Among Epidendroideae, the ten smaller clades (Neottieae, Sobralieae, Tropidieae, Triphoreae, Xerorchideae, Wullschaegelieae, Gastrodieae, Malaxideae, Vandeae, Collabieae) has 22 genera in South America, 21 in Colombia, 19 in Venezuela, 18 in Ecuador and 17 in Brazil.

In Epidendreae, with 70 genera in South America, Colombia has 60 genera, Ecuador 54, Venezuela 53, Peru 52, and Brazil only 51.

In Cymbidieae, South America has 145 genera; Colombia has 108, Ecuador 104, Venezuela 95, Brazil 93, and Peru 90.

SOUTH AMERICAN POACEAE ✅

South America has 234 genera of Poaceae with native species in 11 of 12 subfamilies; in 7 of them Brazil has the primacy in number of genera, with these groups adding up to 136 genera on the continent, 125 in Brazil and 11 absents: five Bambusoideae (where Brazil has 12 endemic genera) and six in Panicoideae (Brazil with 7 endemic genera). The status of the 4 other families are detailed below.

Danthonioideae (19/285) has three genera in South America, Cortaderia Stapf. and Danthonia DC occur in Brazil; Rytidosperma Stued. occur from Malesia to Australasia, Hawaiian Islands, Easter Island and S. South America in Argentina and Chile.

Arundinoideae (11-13/35-38) is a subfamily with a single representative in the Americas, P. australis (Nees) Döll, which curiously occurs in all countries of the Hemisphere, except for the Caribbean islands, Brazil and Paraguay, this being genus probably the most distributed of all the New World genera absent in the country. None of the major platforms (POWO, VPA, WCSPF, Reflora) marks this genus in Brazil. Beauty images of this species in French Guiana can be seen at La Chaussete Rouge (SEE).

Phragmites australis is a cosmopolitan species that has strong effects on the ecosystems it inhabits; it therefore can offer valuable insights into plant responses to global change, with three welll defined lineages, possibly more (Eller et al., Frontiers, 2017); It is a robust and highly productive grass in the Poaceae family that occurs in a wide range of freshwater and brackish wetlands. GBIF shows 7 records of this species in Brazil (SEE), in SE & S Rio de Janeiro to E São Paulo states, also a isolated record in western region of latter states, which are marked on the more general map of the species, which strongly agrees with the maps present in POWO, if we consider all 7 records as insufficient to attest to their native status in the country. 
 

In Chloridioideae, South America has 39 genera; Argentina and Brazil lead in generic diversity, with 28 (Blepharidachne, Scleropogon, Tragus and Willkommia are highly disjuncts, Neobouteloua endemic) and 21 (Triraphis highly disjunct; three endemics), respectively.

Pooideae has 55 genera in South America, only 25 in Brazil. The highest diversity are from Argentina, with 39 genera, Chile 37, Peru 35, Bolivia 32, Colombia and Ecuador 31. For species, South America has 847 spp., only 99 in Brazil, 25 endemics.

Four lineages of Pooideae ocur in South America, four in Brazil (numbers at parenthesis): Meliceae (2/13 spp.), Stipeae (3/32 spp.), Brachypodieae (absent), Triticeae (2/5 spp.) and Poeae (18/48 spp.). Excepting Brachypodieae, all subtribes absents in Brazil belongs Poeae. 
 
Poeae has 16 subtribs in South America, nine absents in Brazil.
