Aphanopsidaceae is a family of lichen-forming fungi in the order Lecanorales. It contains the genera Aphanopsis and Steinia , comprising five species. [1] The family was circumscribed in 1995 by the lichenologists Christian Printzen and Gerhard Rambold. [2]

Description

The Aphanopsidaceae family is a group of lichens characterised by their crustose (crust-like) thallus, which is the main body of the lichen. They engage in a mutualistic relationship with a photobiont , specifically a chlorococcoid type, which refers to the spherical green algae that provide the lichen with nutrients through photosynthesis. [3]

The reproductive structures of Aphanopsidaceae, known as ascomata, are apothecioid , resembling small, open cups. These structures are biatorine , meaning they have a reduced or almost invisible margin around the rim. The internal structure of the ascomata includes a network of paraphyses, which are branched and interconnected filaments. These paraphyses are non-amyloid, indicating they do not react to staining with iodine, a common method used to study fungal microstructures. [3]

The asci, the spore-bearing cells, have thin walls but are distinguished by a distinct apical structure that is strongly amyloid. This apical structure is plug- or tube-shaped and is part of the tholus , the upper part of the ascus. The shape of the asci varies from cylindrical to club-like ( clavate ). Aphanopsidaceae lichens typically produce 8 to 16 spores per ascus. These ascospores are non-septate, meaning they lack internal divisions, and range in shape from spherical (globose) to broadly oval (ellipsoid). They are clear (hyaline) and do not react to amyloid staining. Additionally, Aphanopsidaceae have conidiomata, which are structures that produce asexual spores called conidia. These conidia are non-septate, ellipsoid in shape, and also hyaline. [3]

Gloeoheppiaceae is a family of ascomycete fungi in the order Lichinales. The family contains ten species distributed amongst three genera. Most species are lichenised with cyanobacteria. Species in this family are mostly found in desert areas. Modern molecular phylogenetics analysis casts doubt on the phylogenetic validity of the family, suggesting a more appropriate placement of its species in the family Lichinaceae.

<span class="mw-page-title-main">Lecideaceae</span> Family of lichen-forming fungi

The Lecideaceae are a family of lichens in the order Lecideales. It contains about 30 genera about roughly 250 species. A major distinguishing characteristic of the family is the lecanoroid form of the fruiting bodies: typically circular, dark, and without a thalline margin. Most species in the family are lichenised with green algae, although a few species, scattered amongst several genera, are lichenicolous–they live on other lichens. Lecideaceae lichens tend to grow on rocks, wood, and soil. The largest genus in the family, Lecidea, was once a loosely circumscribed wastebasket taxon containing hundreds of morphologically similar species with generally crustose thalli, photobiont-free apothecial margins and translucent, single-celled ascospores. The overall taxonomy and classification within the family has been made more accurate with recent molecular phylogenetics studies.

<i>Hertelidea</i> Genus of lichens in the family Stereocaulaceae

Hertelidea is a genus of crustose lichens in the family Stereocaulaceae. Characteristics of the genus include carbon-black ring or outer margin (exciple) around the fruit body disc (apothecium), eight-spored, Micarea-type asci and mostly simple, hyaline ascospores that lack a transparent outer layer. Hertelidea species mostly grow on wood, although less frequently they are found on bark or soil. While the type species, Hertelidea botryosa, has a widespread distribution, most of the other species are found only in Australia.

<i>Schaereria</i> Genus of lichen

Schaereria is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes. Most Schaereria species are crustose lichens that live on rocks. Schaereria was first proposed by Gustav Wilhelm Körber in 1855 and was later taken up by other lichenologists despite periods of disuse.

Architrypethelium hyalinum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in Costa Rica and Brazil, it was formally described as a new species in 2008 by lichenologist André Aptroot. The type specimen was collected by Harrie Sipman from the Las Cruces Biological Station in Puntarenas. The lichen has a smooth to uneven, olive-green thallus. Its ascomata occur solitarily, have an apical ostiole, and measure 0.7–1.5 mm in diameter. Ascospores number 4 to 8 per ascus, have an oblong to ellipsoid shape with 3 septa, and measure 100–150 by 30–50 μm. These spores are among the largest of the 3-septate lichens in the Trypetheliaceae. Both the thallus and ascomata contain lichexanthone, a lichen product that causes these structures to glow yellow when lit with a long-wavelength UV light; A. hyalinum is the only species in genus Architrypethelium that contains lichexanthone.
