Typification
Type: BRAZIL, São Paulo, Cananéia, B Parque Estadual da Ilha do Cardoso^ (PEIC), 25°03′05″– 25°18′18″S; 47°53′48″–48°05′42″W, Perequê river (salinity 1.3 %), from leaves of Laguncularia racemosa onto PYGs medium, 27 Feb 2013, A.L. Jesus, C.L.A. Pires-Zottarelli & A.V. Marano (SP 466380, holotype). Is this a valid species. No code of herbaria collection is referred in the manuscript.

Morphological identification

Colonies and cardinal temperatures
Colony colony:
assemblage of hyphae which usually develops form a single source and grows in a coordinated way
with scanty aerial myceliummycelium:
mass of hyphae constituting the body, or thallus, of fungi and oomycetes; in <em>Phytophthora</em> species, mycelia is coenocytic
and no defined growth pattern in PYGs culture medium. Optimum growth temperature 30°C and maximum 35°C.
Asexual phase
Sporangia nonpapillated or semipapillatesemipapillate:
pertaining to the production of shallow having papilla that are not well developed, shallow and less nipple-like than fully papillate structures
; persistentpersistent:
pertaining to sporangia that remain attached to the sporangiophore and do not separate or detach easily (cf. caducous)
; ovoidovoid:
egg-shaped, with the widest part at the base of the sporangium and the narrow part at the apex
to obpyriformobpyriform:
inversely pear-shaped, i.e. with the widest part at the point of attachment (cf. pyriform)
, elongate (55–83 μm long x 43–63 μm wide); producing internal (nested and extended) proliferationproliferation:
formation of a sporangium within an empty sporangium that has previously emitted zoospores (internal or nested) or after the sporangiophore has emerged from the empty sporangium (external)
; produced in unbranched or simple sympodial sporangiophores; sporangia presenting additional vesicle. Hyphal swellings globoseglobose:
having a rounded form resembling that of a sphere
, tubular, or with lobate shape. ChlamydosporesChlamydospores:
an asexual spore with a thickened inner wall that is delimited from the mycelium by a septum; may be terminal or intercalary, and survives for long periods in soil
absent.
NOTE: Additional vesicle in sporangiasporangia:
sac within which zoospores form, especially when water is cooled to about 10°C below ambient temperature; in solid substrates, sporangia usually germinate by germ tubes
has not being observed in Phytophthora.
Sexual phase
Sterile.
