Vermilacinia breviloba

Ciri dan struktur

Similar to V. robusta by the inflated branches and to V. polymorpha by the relatively short length of branches; differs by the honeycomb-like cortex or by the contorted lobes. Thallus 1–1.5 (-2.5) cm high and 0.5–1 cm broad; basal branches 1–5 or rarely more, short cylindrical, teretiform or prismatic, 1–3 mm diam., loosely united at brownish base, ± erect, inflated, irregularly shriveled and contorted when dry, transversely segmented and ruptured when wet at ± regular intervals, terminally divided into short lobes with or without apothecia; terminal lobes often many and close together or fewer and spreading, 4–6 mm long, 2–4 mm diam. Cortex two-layered, 35–50 μm thick, outer thicker, melanized, externally pale olive green, with irregular reticulate cortical ridges, recessed-concave within ridges (honeycomb-like surface), occasionally plicate on inflated lobes. Medulla subfistulose, hyphae flexuous when wet, intertwining in a net arrangement, ± periclinal, frequently uniting into minute knots; Photobiont in small yellow green to green round colonies ± continuous around the perimeter of the medulla. Apothecia many, aggregate terminally on a primary branch, each subtended by a short stalk-like lobe partly deflated and constricted to junction with branch lobe, bowl-shaped when young, to 4 mm diam., lenticular with age; thalline margin thickened, incurved, entire or crenulate or incised, disc pale orange, concave; asci 8-spored; spores opaque, 1-septate, short ellipsoid, 6–7 × 4–5 μm. Pycnidia black, common on the upper half of branches in shallow concave depressions within cortical ridges, ostiole flush with cortical surface, immersed below; conidia not observed.

Habitat dan peran ekologis

Mexico, Baja California, North Vizcaíno Desert, between Punta Santa Rosalillita and Punta Negra. Only known from that locality. On rock ledges of north-facing cliffs bordering estuary inland from the sea, occurring with species of Niebla, Vermilacinia cedrosensis and V. paleoderma, within a semicircular arc of volcanic coastal hills with steep ravines and narrow ridges trending in various directions, 200–400 m in altitude, extending approx. 20 km along the coast and to 7 km inland at midpoint near the Punta Negra Road (Google Earth 2019). Fog often lingers amongst the higher ridges and peaks during the day (Spjut 1996). A diversity of saxicolous Vermilacinia occurs here: V. breviloba, V. cedrosensis, V. ligulata, V. paleoderma, V. pustulata, V. reptilioderma and V. rigida. Vegetation on hills near type locality consists of spiny shrubs and succulents of Pachycormus discolor, Stenocereus thurberi, Cylindropuntia spp., Fouquieria diguetii and Agave shawii. The subshrub Xylonagra arborea was observed on rocks amongst the lichens and salt-scrub of Atriplex julacea and Frankenia palmeri bordered a salt marsh of aquatic species not studied.
