Ciri dan struktur

The cap is 5–19 cm in diameter and initially almost hemispherical in shape, transforming to broadly convex and finally to flattened or with edges upturned in age. The cap surface is dry, with fibrils when young, but later the fibrils form large, dark brown appressed squamules (2–9 mm long by 2–5 mm broad). The cap color may be various shades of brown depending on the maturity of the specimen. The cap flesh is typically 1–3 cm thick, firm, white, and stains deep red 20–30 seconds after injury or bruising. The odor immediately after cutting is mild, faintly spicy, but after several minutes can be described as fruity. The gills are free in attachment, closely spaced, 5–15 mm broad, and marginate. The light-cinnamon color in young specimens turns to a dark blackish brown in age after the spores develop. Bruised gills stain a vinaceous (wine-colored) red. The stipe is usually 8–18 cm long by 2.5–4 cm thick with a bulbous shape. The interior is hollow, with the internal cavity being between 5 and 9 mm thick. The stipe context somewhat fibrous and white in color, except for the basal section which is yellowish. Bruising or cutting results in a red stain after a minute. The surface of the stipe is barely striate above the annulus, and smooth below except for fragments of the universal veil. During development the veils rupture and form an upper veil (partial veil), which initially hangs from the edge of the cap, and a lower veil. As the partial veil disintegrates, it often leaves fragments 2–3 mm in size attached to the margin. The spores are roughly elliptical in shape, 7–8.5 by 5.5–6.5 μm.

Habitat dan peran ekologis

Agaricus pattersoniae dikaitkan dengan pohon Hesperocyparis macrocarpa (Monterey cypress) yang berbuah secara individual atau dalam kelompok. Richard Kerrigan noted bahwa tampaknya terbatas pada pohon matang (umur 40+ tahun) yang terletak di daerah pesisir California, meskipun Alexander H. Smith mentions bahwa itu juga telah ditemukan di Great Lakes regions. Spesies ini telah diusulkan untuk dimasukkan ke dalam bagian IUCN Red List of Threatened Species as dari Global Fungal Red List Initiative. Ancaman utama termasuk kerusakan habitat, kekeringan, dan penurunan pohon sipres karena kanker sipres dari infeksi oleh Seiridium cardinale. Pohon sapres telah dihapus dari lokasi jenis.

Reproduksi

The gills are free in attachment, closely spaced, 5–15 mm broad, and marginate. The light-cinnamon color in young specimens turns to a dark blackish brown in age after the spores develop. Bruised gills stain a vinaceous (wine-colored) red. The spores are roughly elliptical in shape, 7–8.5 by 5.5–6.5 μm. The basidia, which may be 1–, 2–, 3–, or 4–spored (although usually 4–spored during active sporulation), are 26–34 by 7–11 μm, cylinder- to club-shaped, with sterigmata that are 2–3 μm long. The cheilocystidia are 12–32 by 6–15 μm in size, almost cylindrical or club-shaped, and may appear clumped or continuous.

Ekologi sumber

Agaricus pattersoniae is associated with Hesperocyparis macrocarpa (Monterey cypress) trees, fruiting singly or in groups. Richard Kerrigan noted that it seems to be restricted to mature trees (age 40+ years) located in the coastal counties of California, although Alexander H. Smith mentions that it has also been found in the Great Lakes regions. The species has been proposed for inclusion in the IUCN Red List of Threatened Species as part of the Global Fungal Red List Initiative. Its main threats include habitat destruction, drought, and decline of cypress trees due to cypress canker from infection by Seiridium cardinale. The cypress trees have been removed from the type locality.
